What are Stokes Germany Front Upper Control Arms for Mercedes-Benz GLS X167 AMG Models and what do they do?
Mercedes-Benz GLS X167 AMG Front Upper Control Arms are important components of the front suspension system that help locate and guide the front wheel assemblies as the suspension moves during normal driving, braking, acceleration, cornering and travel over uneven road surfaces. This Stokes Germany Front Upper Control Arm Set of 2 for Mercedes-Benz GLS X167 AMG Models A1673306800 & A1673306700 provides the corresponding right and left upper suspension arms together in one replacement package. For this application, A1673306800 corresponds to the front upper right position and A1673306700 corresponds to the front upper left position, and Mercedes-Benz's official parts information includes these references on Mercedes-AMG GLS 63 applications in the 167 series. The upper control arms form part of the complete front suspension rather than operating independently. They work alongside the lower control arms, suspension bushes, steering components, shock absorbers, wheel hubs, wheel bearings, tyres and stabilizer components to help maintain controlled wheel movement. When the Mercedes-Benz GLS X167 AMG travels over potholes, speed breakers, damaged roads or uneven surfaces, the front wheels move vertically as the suspension compresses and extends. The upper control arms help guide this movement through the suspension's intended path while restricting excessive unwanted movement. During braking, substantial forces are transferred through the tyres and wheels into the suspension assembly. Cornering generates lateral forces, while acceleration and road impacts continuously change the loads passing through the suspension components. The bushes and applicable joints associated with the upper control arms therefore need to remain mechanically sound. With mileage and repeated suspension movement, these components can gradually deteriorate and develop excessive movement. A worn upper control arm may contribute to knocking or clunking from the front suspension, less precise steering, unwanted suspension movement or irregular tyre wear. These symptoms should still be professionally diagnosed because lower control arms, steering joints, tyres, wheel bearings and other suspension components can create similar problems. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when knocking or rattling is present. This is especially important on the GLS X167 because selecting the correct suspension configuration matters; A1673306800 & A1673306700 should not automatically be treated as universal upper arms for every GLS X167. The AMG application, original part references and VIN should be checked before ordering. When professional inspection confirms wear in these positions, replacing the applicable Mercedes-Benz GLS X167 AMG Front Upper Control Arms can address excessive mechanical movement originating from the worn components.
Are A1673306800 & A1673306700 suitable for Mercedes-Benz GLS X167 AMG Models?
A1673306800 & A1673306700 are suitable references for applicable Mercedes-Benz GLS X167 AMG front upper suspension applications, but the exact vehicle and VIN should always be verified before ordering because Mercedes-Benz uses different control-arm references across different GLS X167 suspension configurations. Mercedes-Benz identifies A1673306800 as an upper-right control arm and A1673306700 as an upper-left control arm, and its official fitment information specifically includes Mercedes-AMG GLS 63/63 S 4MATIC+ 167 applications among the vehicles using these components. Independent suspension information also associates A1673306700 and A1673306800 with the front upper position for GLS X167 and specifically notes an AMG-package application. Your current Stokes Germany product listing identifies this product as a Front Upper Control Arm Set of 2 for Mercedes-Benz GLS X167 AMG Models A1673306800 & A1673306700 and specifies a 2019–2026 vehicle range. This makes the exact OEM references particularly important during product selection. A customer should first confirm that the vehicle is a Mercedes-Benz GLS X167 with the applicable AMG suspension configuration. The original front upper control-arm references should then be compared with A1673306800 and A1673306700. A1673306800 should correspond with the required right-side component, while A1673306700 should correspond with the required left-side component. If the original numbers cannot be confidently established, VIN verification is recommended. Mercedes-Benz's own parts pages provide compatibility checking based on the vehicle's 17-digit VIN, which reinforces the importance of chassis-specific confirmation. Customers should not select these components solely because their vehicle is a GLS X167 or because the replacement arms visually resemble the original components. Suspension arms can differ in geometry, mounting locations, bush arrangement or application despite looking similar. This distinction is also visible in the current GLS X167 product catalogue, where A1673301300 & A1673301400 are offered as another upper-control-arm pair for GLS X167 applications. Therefore, the safest purchasing process is to confirm the Mercedes-Benz GLS X167 AMG vehicle specification, compare the original part numbers, check the required right and left suspension positions and verify the VIN before purchasing this Stokes Germany Set of 2.
What are the common symptoms of worn Mercedes-Benz GLS X167 AMG Front Upper Control Arms?
Common symptoms that may be associated with worn Mercedes-Benz GLS X167 AMG Front Upper Control Arms include knocking or clunking from the front suspension, excessive movement over uneven roads, less precise steering response, changes in front-end stability and irregular tyre wear, although none of these symptoms alone proves that A1673306800 or A1673306700 requires replacement. These upper control arms help locate the front wheel assemblies while allowing the suspension to move through its intended travel. A1673306800 is associated with the front upper right position and A1673306700 with the corresponding front upper left position for the applicable AMG configuration. During normal driving, the control arms and their associated bushes or joints experience repeated movement as the vehicle brakes, accelerates, corners and passes over changing road surfaces. Potholes and speed breakers create rapid suspension movement, while braking and cornering place additional forces through the suspension links and mounting points. With mileage and normal wear, deterioration in a bush or applicable joint can permit more movement than intended. A knocking or clunking sound may then become noticeable when the suspension moves over potholes, broken surfaces or speed breakers. If excessive movement affects wheel positioning under changing loads, the steering may feel less precise or the front end may require additional correction. Irregular tyre wear can sometimes accompany suspension wear if unwanted movement contributes to changes in wheel geometry, although incorrect tyre pressure and wheel alignment can create similar wear patterns. Vibration should be diagnosed particularly carefully because wheel imbalance, tyre damage, bent wheels and wheel-bearing wear are also common sources of vibration. Front lower control arms and their bushes should therefore be inspected whenever upper-arm wear is suspected. Steering tie rod ends and related steering joints should be checked for excessive play. Shock absorbers should be examined for leakage, physical damage and damping condition. Wheel bearings should be checked when humming, vibration or excessive wheel movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected because worn stabilizer joints can create knocking noises that may be mistaken for control-arm wear. Tyres and wheels should also be inspected before concluding that the Mercedes-Benz GLS X167 AMG Front Upper Control Arms are responsible. When professional inspection confirms excessive play or deterioration in A1673306800 & A1673306700, replacing the affected upper control arms can address the unwanted movement originating from those specific suspension positions.
Why are Mercedes-Benz GLS X167 AMG Front Upper Control Arms A1673306800 & A1673306700 supplied as a Set of 2?
The Mercedes-Benz GLS X167 AMG Front Upper Control Arms A1673306800 & A1673306700 are supplied as a Set of 2 because the package provides corresponding right and left front upper suspension arms rather than two identical interchangeable components. Mercedes-Benz identifies A1673306800 as the upper-right component and A1673306700 as the upper-left component, with both references appearing in Mercedes-AMG GLS 63 applications in the 167 series. This Stokes Germany Front Upper Control Arm Set of 2 therefore allows customers to purchase the corresponding upper suspension positions together when both have been diagnosed as requiring replacement. Both sides of the front suspension generally experience the same overall vehicle mileage, but this does not mean that the right and left control arms will necessarily wear at exactly the same rate. One side of the vehicle may experience more potholes, damaged road surfaces, kerb impacts or other loads. Previous repair history can also result in one arm having substantially less mileage than the opposite component. For this reason, the fact that the product is supplied as a Set of 2 does not mean that both original components must automatically be considered defective whenever one arm shows wear. The correct approach is to inspect both sides. If A1673306800 and A1673306700 positions both show deterioration, excessive bush movement, joint play or another confirmed defect, replacing the corresponding pair during the same suspension repair can be practical. Surrounding components should also be inspected at the same time. The front lower control arms and their bushes should be checked, along with steering joints, shock absorbers, wheel bearings and tyres. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be inspected when suspension noise is present. Correct right and left installation is essential because A1673306800 & A1673306700 are position-specific references. The current product listing identifies the Stokes Germany package as a Set of 2 for Mercedes-Benz GLS X167 AMG Models and specifies 2019–2026 compatibility, subject to correct vehicle fitment. VIN and original part-number verification should therefore be completed before ordering, especially because other GLS X167 suspension configurations can use different upper-control-arm references.
What are the benefits of replacing worn Front Upper Control Arms on Mercedes-Benz GLS X167 AMG Models?
Replacing worn Mercedes-Benz GLS X167 AMG Front Upper Control Arms can help remove excessive mechanical play from the affected upper suspension positions, restore more controlled wheel movement and address knocking, steering or suspension symptoms when professional diagnosis confirms that the original control arms are the source of those problems. The upper right A1673306800 and upper left A1673306700 components help locate and guide the corresponding front wheel assemblies while the suspension moves, and Mercedes-Benz confirms these right/left positions for the applicable 167-series applications. When a control-arm bush or applicable joint becomes worn, additional movement can occur as suspension loads change. During braking, the wheels and suspension experience substantial longitudinal forces. During cornering, lateral forces pass through the tyres, wheels and suspension links. Potholes and damaged roads introduce rapid vertical suspension movement. If the upper control arms contain excessive play, these changing loads can produce unwanted movement. When that movement is responsible for a knocking or clunking sound, replacing the worn components can address the mechanical source of the noise. If excessive upper-arm movement is contributing to less precise wheel positioning, replacement can also help restore more controlled movement at those suspension positions. Correcting mechanical wear is also important before wheel alignment because alignment equipment measures geometry but cannot compensate for a loose suspension joint or deteriorated bush. However, customers should not expect new A1673306800 & A1673306700 control arms to correct every possible front suspension problem. Worn lower control arms require separate repair. Loose steering joints, worn wheel bearings, damaged tyres or defective shock absorbers will continue to create symptoms until those components are addressed. Knocking caused by Sway bar links, Sway links, Anti roll link rods or Stabiliser sway links will also remain until the relevant stabilizer components are repaired. Existing irregular tyre wear cannot be reversed by fitting new suspension arms. Therefore, the greatest benefit comes when the Mercedes-Benz GLS X167 AMG Front Upper Control Arms have first been correctly diagnosed as worn, the exact AMG application and OEM references are verified, the components are professionally installed and the remaining front suspension is confirmed mechanically sound. A professional wheel alignment check after the repair then provides an opportunity to measure the wheel geometry with the suspension in its repaired condition.
What should be checked before buying Stokes Germany Mercedes-Benz GLS X167 AMG Front Upper Control Arms?
Before buying Stokes Germany Mercedes-Benz GLS X167 AMG Front Upper Control Arms, customers should confirm the exact Mercedes-Benz model, GLS X167 chassis code, AMG suspension application, original OEM references, required right and left positions and vehicle VIN because the GLS X167 family can use different upper-control-arm configurations. The product being offered is Stokes Germany Front Upper Control Arm Set of 2 for Mercedes-Benz GLS X167 AMG Models A1673306800 & A1673306700, and the current product listing specifies Mercedes-Benz GLS X167 2019–2026 compatibility. Mercedes-Benz identifies A1673306800 as an upper-right control arm and A1673306700 as an upper-left control arm, and both official parts pages include Mercedes-AMG GLS 63 applications within their fitment information. Independent suspension data also links A1673306700/A1673306800 with GLS X167 and specifically notes an AMG-package application. This is important because the current GLS X167 catalogue also contains A1673301300 & A1673301400 as another front upper control-arm set, meaning a customer should not assume that every GLS X167 requires A1673306800 & A1673306700. The original component numbers should be checked first. If the numbers cannot be confidently confirmed, the 17-digit VIN should be used for compatibility verification. Mercedes-Benz's official parts pages specifically provide VIN-based fitment checking for these references. Customers should also confirm why the control arms are being replaced. Knocking does not automatically mean that the upper arms are worn because lower control arms, stabilizer links and steering components can generate similar noises. Vibration may originate from tyre imbalance, damaged wheels or wheel bearings. Uneven tyre wear may be caused by suspension wear, incorrect alignment, tyre pressure or several factors working together. A complete suspension inspection is therefore recommended before ordering. Front lower arms, suspension bushes, steering tie rod ends, shock absorbers, wheel bearings, tyres, wheels, Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be checked according to the reported symptoms. Once the vehicle is confirmed as the applicable Mercedes-Benz GLS X167 AMG configuration, the original references correspond with A1673306800 & A1673306700 and inspection confirms that the front upper control arms require replacement, this Stokes Germany Set of 2 can be selected for the corresponding front upper suspension repair.
Why are Mercedes-Benz GLS X167 AMG Front Upper Control Arms important for suspension, steering and road handling?
Mercedes-Benz GLS X167 AMG Front Upper Control Arms are important components of the front suspension because they help locate and guide the front wheel assemblies while the suspension responds to braking, acceleration, cornering, potholes, speed breakers and changing road surfaces. In this Stokes Germany Front Upper Control Arm Set of 2 for Mercedes-Benz GLS X167 AMG Models A1673306800 & A1673306700, A1673306800 corresponds to the front upper right position and A1673306700 corresponds to the front upper left position. Mercedes-Benz's parts information includes these references on Mercedes-AMG GLS 63 applications, while independent suspension catalogues also associate the pair with the GLS X167 AMG suspension configuration. The upper control arms work as part of the complete suspension system rather than controlling the vehicle independently. When the front wheel moves upward after encountering a pothole or road irregularity, the suspension compresses and the control arms help guide the wheel assembly through its designed path. As the wheel moves downward again, the suspension extends while the arms continue controlling its relationship with the chassis. During braking, longitudinal forces travel through the tyres, wheels and suspension. During cornering, lateral forces act through the same components, while acceleration and road impacts continually alter the loads acting on the suspension. The control-arm bushes and applicable joints therefore need to allow the required suspension movement while restricting excessive movement that could negatively influence wheel positioning. If wear develops in an upper control-arm bush or joint, additional movement can occur under load. The driver may then notice knocking over rough roads, reduced front-end precision, steering that requires additional correction or irregular tyre wear. These symptoms can become more noticeable as component wear increases, but proper diagnosis remains important because other suspension components can create similar problems. Front lower control arms, steering tie rod ends, shock absorbers, wheel bearings and tyres should therefore be checked whenever upper-control-arm wear is suspected. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when knocking or rattling occurs over uneven roads because stabilizer-link wear can produce similar noises. Correct component selection is particularly important for the AMG suspension application. The GLS X167 catalogue includes other upper-arm references for different configurations, so the vehicle should not be matched using only “GLS X167.” The AMG configuration, A1673306800 & A1673306700 references and VIN should be verified before purchase. When the correct components are fitted and the complete suspension is mechanically sound, the Mercedes-Benz GLS X167 AMG Front Upper Control Arms contribute to controlled wheel movement and consistent front suspension operation.
Is wheel alignment necessary after replacing Mercedes-Benz GLS X167 AMG Front Upper Control Arms?
A professional wheel alignment check is recommended after replacing Mercedes-Benz GLS X167 AMG Front Upper Control Arms because these suspension components participate in controlling the position and movement of the front wheel assemblies, and replacing worn control arms changes the mechanical condition from which wheel geometry is measured. This Stokes Germany Set of 2 provides A1673306800 for the front upper right position and A1673306700 for the front upper left position, with these respective positions confirmed by Mercedes-Benz and independent suspension catalogues. When an original control-arm bush or applicable joint develops excessive wear, the wheel assembly can move more than intended as the vehicle brakes, corners or travels over uneven roads. If alignment measurements are performed while suspension components still contain excessive play, the measured geometry may not accurately represent the wheel position under different loads. Mechanical suspension wear should therefore be corrected before the final alignment is performed. Installing new A1673306800 & A1673306700 upper control arms removes the unwanted movement associated with the worn components, assuming those components were correctly diagnosed, but installing the new arms alone does not establish whether the wheel geometry is within the correct specification. A professional alignment check allows the technician to measure the applicable geometry after the suspension has been repaired. This can be especially important if the vehicle previously showed steering pull, irregular tyre wear or inconsistent straight-line behaviour. Before alignment, however, the remaining front suspension should be inspected. Front lower control arms and their bushes should be checked for excessive movement, cracking, separation or deterioration. Steering tie rod ends and related steering joints should be checked for play. Shock absorbers should be inspected for leakage, physical damage and damping condition. Wheel bearings should be checked if humming, vibration or wheel movement is present. Tyres should be examined for correct inflation pressure, tread condition and abnormal wear, while wheels should be inspected for damage or balancing problems. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when front suspension noise is present. These stabilizer components serve a different purpose and are not corrected through wheel alignment, but unresolved wear can still affect how the front suspension feels after repair. Correct installation procedures for A1673306800 and A1673306700 should also be followed because they are position-specific right and left components. After all relevant mechanical problems have been repaired, checking wheel alignment provides an important final stage of the Mercedes-Benz GLS X167 AMG front suspension repair.
Can worn Mercedes-Benz GLS X167 AMG Front Upper Control Arms cause knocking, vibration, loose steering or uneven tyre wear?
Worn Mercedes-Benz GLS X167 AMG Front Upper Control Arms can contribute to knocking or clunking, excessive front suspension movement, less precise steering and irregular tyre wear if deterioration in a bush, applicable joint or mounting area allows the wheel assembly to move more than intended, although none of these symptoms should automatically be treated as proof that A1673306800 or A1673306700 is defective. These upper control arms operate continuously while the vehicle is being driven because the suspension repeatedly compresses and extends as road conditions change. During braking, substantial loads pass through the front suspension. Cornering introduces lateral forces, acceleration changes the loading of the chassis and potholes can create rapid suspension movement. Over time, repeated movement and normal component ageing can contribute to deterioration in suspension bushes and joints. When excessive play develops, a knocking or clunking sound may become noticeable as the suspension changes direction over potholes, road joints or speed breakers. The sound may appear to come from one side or generally from the front suspension depending on the source and severity of wear. Steering can also feel less precise when unwanted suspension movement influences wheel positioning under changing loads. The driver may feel that the GLS requires additional correction when travelling straight or that the front end does not respond as consistently as expected. Irregular tyre wear may sometimes occur when suspension wear contributes to changes in wheel geometry. However, tyre pressure and incorrect wheel alignment can produce similar patterns. Vibration should be diagnosed particularly carefully because wheel imbalance, damaged tyres, bent wheels and worn wheel bearings are common alternative causes. Lower control-arm bushes and joints can also create knocking and steering symptoms. Steering tie rod ends should therefore be checked for excessive movement. Shock absorbers should be inspected for leakage and damping condition. Wheel bearings should be assessed where humming, vibration or excessive wheel movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be inspected when knocking occurs over smaller road irregularities because worn stabilizer-link joints can create sounds that are easily mistaken for control-arm wear. A professional front suspension inspection should therefore identify the actual source of the complaint before A1673306800 & A1673306700 are replaced. When excessive movement is confirmed in these upper suspension positions, replacement can address the mechanical play originating from the worn arms. The product is specifically listed for Mercedes-Benz GLS X167 2019–2026 and uses the A1673306800 & A1673306700 OEM cross-reference pair.
What other suspension parts should be checked when replacing Mercedes-Benz GLS X167 AMG Front Upper Control Arms?
When replacing Mercedes-Benz GLS X167 AMG Front Upper Control Arms, the complete front suspension, steering system, wheels and tyres should be inspected because A1673306800 & A1673306700 operate as part of an interconnected suspension system and installing new upper arms will not correct wear in surrounding components. The front lower control arms should be inspected first because their bushes and joints also contribute to locating the wheel assemblies. Suspension bushes should be checked for cracking, separation, deformation or excessive movement. Applicable ball joints should be checked for play and damaged protective boots because contamination can accelerate joint wear when a protective boot is compromised. Steering tie rod ends and related steering joints should be checked because excessive steering-joint movement can contribute to knocking, loose steering and irregular tyre wear. Shock absorbers should be inspected for leakage, physical damage and damping condition because they control the rate of suspension movement and significantly influence how the front suspension responds after encountering road irregularities. Wheel bearings should be checked if the customer reports humming, vibration or excessive wheel movement. Wheels should be inspected for impact damage, while wheel balancing should be considered where speed-related vibration is present. Tyres should be checked for correct pressure, tread depth, damage and abnormal wear patterns. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should receive particular attention if the complaint includes knocking or rattling over potholes because stabilizer-link wear can produce noises similar to those associated with control arms. Stabilizer mounting bushes should also be inspected where applicable. The opposite-side upper arm should always be assessed when one side is found to have excessive wear. For this AMG application, A1673306800 corresponds to the front upper right control arm and A1673306700 corresponds to the front upper left control arm. Both components are supplied together in the Stokes Germany Set of 2, but the fact that they are sold together should not replace mechanical diagnosis. The mounting locations and applicable hardware should also be inspected during installation, and the correct vehicle-specific workshop procedure should be followed. Fitment verification is especially important because independent catalogue information marks the A1673306700/A1673306800 family for the AMG package, while GLS X167 catalogues also contain different front upper control arms for other configurations. Once all relevant mechanical wear has been addressed, a professional wheel alignment check is recommended. This complete inspection approach reduces the risk of installing new Mercedes-Benz GLS X167 AMG Front Upper Control Arms while another worn suspension or steering component continues causing the original complaint.
Why is Stokes Germany a European-quality alternative to Lemförder, FEBI, Meyle and other established brands for Mercedes-Benz GLS X167 AMG Models?
Stokes Germany is a European-quality alternative to Lemförder, FEBI, Meyle and other established aftermarket suspension brands for Mercedes-Benz GLS X167 AMG Models because it offers application-specific replacement suspension components focused on correct OEM-reference matching, accurate fitment, practical warranty support and competitive value for premium European vehicles. For the Mercedes-Benz GLS X167 AMG Front Upper Control Arm Set of 2, JK Automotive lists Stokes Germany with exact OEM cross references A1673306800 & A1673306700 for Mercedes-Benz GLS X167 applications from 2019–2026 and provides a 6 Months Warranty Against Manufacturing Defects. When comparing Stokes Germany with Lemförder, FEBI, Meyle or another established suspension brand, the most important factors are not simply the brand name or packaging but whether the replacement control arms correspond with the vehicle's exact chassis, suspension configuration, OEM references, mounting arrangement and required left/right application. This is especially important for Mercedes-Benz GLS X167 AMG Models because AMG and non-AMG suspension applications should not automatically be assumed to use interchangeable control arms. Stokes Germany therefore provides a useful alternative for customers who specifically require the A1673306800 & A1673306700 application and want to purchase the corresponding pair rather than selecting components only by vehicle model. The Set of 2 configuration can also be convenient when both corresponding front upper control arms are confirmed worn and are being renewed during the same suspension repair. Established manufacturers such as Lemförder, FEBI and Meyle have strong positions in the European aftermarket, but Stokes Germany can be considered alongside these brands when evaluating fitment, complete-set availability, warranty terms and overall purchase value. It is important, however, not to claim that Stokes Germany components are identical to Lemförder, FEBI or Meyle products, manufactured to exactly the same specification, produced in the same factory, or universally superior in durability unless product-specific independent evidence establishes those facts. Different aftermarket brands can use different materials, rubber compounds, manufacturing processes, dimensional tolerances and quality-control specifications even when their products cross-reference the same Mercedes-Benz OEM numbers. For this reason, OEM references should primarily be used to identify the intended application rather than as proof that products from different manufacturers are technically identical. For Mercedes-Benz GLS X167 AMG Models, customers should confirm chassis code X167, AMG suspension specification, vehicle VIN and original control-arm references before ordering. The replacement arms should also be physically compared with the original components before installation. When A1673306800 & A1673306700 are confirmed as the correct application, the Stokes Germany Front Upper Control Arm Set of 2 offers a practical European-oriented aftermarket choice for customers seeking a balance of application-specific fitment, complete-pair convenience, warranty support and competitive value compared with Lemförder, FEBI, Meyle and other established replacement suspension brands. Professional installation is recommended, and wheel-alignment verification should be carried out after control-arm replacement to ensure that the relevant suspension geometry is checked following the repair.
