What is the Stokes Germany Rear Lower And Upper Control Arm Complete Set of 6 for Mercedes-Benz GLS X166?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online from Stokes Germany is a comprehensive rear suspension replacement package supplied as a Set of 6 for Mercedes-Benz GLS X166 (2016–2020). The exact OEM cross references supplied with this product are A1663500106 & A1663500206 & A1663500306 A1663500053, and JK Automotive confirms the same reference combination, Set of 6 quantity, GLS X166 model and 2016–2020 compatibility in its current product catalogue. The purpose of this complete package is to provide multiple corresponding rear lower and upper suspension arms together for a broader rear suspension repair where professional inspection confirms wear, deterioration, excessive movement or physical damage affecting several components. The Mercedes-Benz GLS X166 rear suspension uses multiple control arms and suspension links to locate the rear wheel assemblies while allowing controlled suspension movement during acceleration, braking, cornering and travel over uneven road surfaces. These suspension arms operate under repeated loads throughout the vehicle's service life, and their rubber-bushed mounting points can gradually deteriorate with age, mileage, heat, contamination and repeated suspension movement. Severe potholes, broken road surfaces or kerb impacts can also potentially damage or deform suspension components. Independent suspension catalogue information supports the OEM-reference applications used in this package: RIW identifies A1663500306 as a rear lower-forward control arm suitable for both left and right positions, A1663500053 as a rear control arm applicable left and right, A1663500206 as a rear upper-right control arm and A1663500106 as a rear upper-left control arm for the X166 platform. This helps explain how four principal OEM references can correspond to six physical components in the complete Stokes Germany package. The Set of 6 should not be interpreted as six unique OEM references, and additional part numbers should never be invented merely to make the number of references equal the physical component quantity. When the existing arms or their bushes become worn, possible symptoms can include rear suspension knocking or clunking, unwanted movement, reduced stability, changes in handling and abnormal rear tyre wear. However, these symptoms can also originate from shock absorbers, springs, wheel bearings, wheels, tyres or stabilizer-system components, so professional diagnosis should determine the actual cause before parts are replaced. The Stokes Germany package should be treated as the definitive reference for the six physical components supplied. Each new arm should be compared with the corresponding original component for geometry, mounting points, orientation and bush configuration before installation. Separate bolts, nuts or other installation hardware should not be assumed to be included unless confirmed by the actual package. VIN and OEM-reference verification are recommended before ordering, followed by professional installation and complete wheel-alignment verification after the suspension work is finished.
Which OEM numbers are included in the Mercedes-Benz GLS X166 Rear Control Arm Complete Set of 6?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online covers the exact OEM references A1663500106, A1663500206, A1663500306 and A1663500053 and is supplied by Stokes Germany as a physical Set of 6 for Mercedes-Benz GLS X166 (2016–2020). JK Automotive's current product listing confirms the exact OEM-reference group, GLS X166 application and six-piece quantity. These OEM references are particularly useful because the X166 rear suspension contains several wheel-locating components that can look similar while differing in position, orientation or mounting geometry. Independent RIW suspension catalogue information provides useful position data: A1663500106 is listed as a rear upper-left control arm, A1663500206 as a rear upper-right control arm, A1663500306 as a rear lower-forward control arm suitable for left and right positions, and A1663500053 as another rear control arm suitable for left and right positions. This mapping provides a logical explanation for the complete six-piece configuration: one A1663500106 application, one A1663500206 application, two corresponding A1663500306 applications and two corresponding A1663500053 applications can account for six physical suspension arms. However, the actual Stokes Germany package remains the final reference for the precise contents delivered, and the parts should be physically checked rather than relying solely on an assumed quantity calculation. Suspension terminology can also differ between catalogues. A component described as a control arm by one manufacturer may be described as a track control arm, lateral arm, cross rod or suspension link by another. For example, independent catalogue information describes A1663500306 as a rear lower-forward track control arm for the Mercedes GLS X166. Therefore, OEM-reference matching, physical comparison and VIN verification should take priority over generic component terminology. Before installation, all six Stokes Germany components should be arranged and matched with their corresponding original arms. The technician should compare overall length, geometry, mounting-eye positions, bush arrangement and installation orientation. If an original Mercedes-Benz component displays a different reference, it should be determined whether that number represents a valid supersession or alternative reference before the replacement component is installed. Matching an OEM cross reference identifies an intended replacement application, but it does not by itself establish that Stokes Germany and Mercedes-Benz Genuine, Lemförder, FEBI, Meyle or another manufacturer use identical materials, manufacturing processes or bush compounds. For that reason, compatibility claims should remain focused on the supplied OEM-reference cross matches and verified vehicle application.
What are the symptoms of worn rear lower and upper control arms on Mercedes-Benz GLS X166?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online may become relevant when professional inspection confirms wear, deterioration or physical damage affecting several corresponding rear suspension control arms on a Mercedes-Benz GLS X166 (2016–2020). Rear control arms are wheel-locating suspension components that help maintain the designed position of the rear wheel assemblies while still allowing the suspension to move through its operating range. During normal driving, these arms and their bushes experience repeated loads as the vehicle accelerates, brakes, changes direction and travels over uneven road surfaces. With increasing age and mileage, rubber-bushed mounting points can deteriorate, crack, separate or permit excessive movement. Significant pothole or kerb impacts can also potentially bend or damage an individual suspension component. Possible symptoms that justify inspection include knocking or clunking from the rear suspension, particularly when travelling over uneven roads or speed breakers, unwanted movement from the rear of the vehicle, reduced stability when changing direction, changes in handling response and abnormal or irregular rear tyre wear. A worn bush can allow an arm to move more than intended as loads change during acceleration, braking and cornering. However, these symptoms do not prove by themselves that all six rear control arms need replacement. A knocking noise can originate from Sway bar links, Sway links, Anti roll link rods or Stabiliser sway links, while poor ride control can also involve shock absorbers or springs. Wheel bearings can cause noise or unwanted movement, and damaged wheels, incorrectly inflated tyres or irregular tyre wear can affect handling and vibration. A qualified technician should therefore perform a systematic inspection rather than replacing parts based only on symptoms. Each rear suspension arm should be checked for excessive movement, deteriorated rubber, bush separation, corrosion, impact damage and physical deformation. The surrounding mounting points should also be examined, especially where the vehicle has experienced a major road impact. The exact Stokes Germany Set of 6 uses OEM references A1663500106, A1663500206, A1663500306 and A1663500053, and JK Automotive confirms these references for the GLS X166 (2016–2020). Independent catalogue evidence further confirms that these numbers represent multiple left, right and both-side rear control-arm applications on the X166 platform. If several corresponding arms have accumulated similar mileage and professional inspection confirms that multiple bushes or arms are worn, replacing the appropriate components together with the complete Set of 6 can provide a coordinated approach to the repair. If only one component is defective and the remaining suspension components are serviceable, the existence of a complete kit does not automatically mean every component must be replaced. The repair scope should be determined from the vehicle's actual condition. After the required rear control-arm replacement has been completed correctly, professional wheel-alignment verification is strongly recommended.
What is included in the Stokes Germany Mercedes-Benz GLS X166 Rear Lower And Upper Control Arm Complete Set of 6?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online from Stokes Germany is specifically supplied as a Rear Lower And Upper Control Arm Complete Set of 6 for Mercedes-Benz GLS X166 (2016–2020), covering OEM references A1663500106 & A1663500206 & A1663500306 A1663500053. JK Automotive's current product information confirms the Set of 6 quantity, GLS X166 application, exact four OEM-reference groups and Stokes Germany brand. Independent catalogue information helps clarify the six-component structure. RIW identifies A1663500106 as a rear upper-left control arm and A1663500206 as a rear upper-right control arm. It identifies A1663500306 as a rear lower-forward control arm used on both left and right positions and A1663500053 as another rear control-arm application used on both left and right positions. Therefore, the fact that this package contains six physical components while only four primary OEM references are listed is not inherently contradictory; some reference families are used in corresponding left-and-right positions. The product should nevertheless be described according to the actual Stokes Germany package rather than assuming or inventing additional OEM numbers. This Set of 6 is a rear lower and upper control-arm package, not a claim that every component of the Mercedes-Benz GLS X166 rear suspension is included. Shock absorbers, springs, wheel hubs and wheel bearings should not be represented as included. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links are separate suspension components and should also not be described as part of the package unless they are specifically shown and confirmed in the actual product contents. Similarly, bolts, nuts, washers, eccentric hardware or other mounting fasteners should not automatically be assumed to be included. Before fitting, the workshop should arrange all six replacement arms and identify the corresponding original component for each one. Overall geometry, length, bush configuration, mounting holes, orientation and installation side should be compared carefully. This physical comparison is particularly important because suspension manufacturers and catalogues can use different names for similar components. A part may be called a control arm, track control arm, lateral arm, cross rod or suspension link depending on the catalogue. OEM-reference verification therefore provides a stronger identification method when combined with physical comparison and VIN checking. If any replacement component differs materially from the original arm, installation should stop until the reason has been established. This prevents an incorrect component from being installed solely because it appears in a generic model-level catalogue.
Should all 6 rear lower and upper control arms be replaced together on Mercedes-Benz GLS X166?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online provides a convenient Stokes Germany six-piece package for a coordinated rear suspension repair, but the presence of a Set of 6 does not automatically mean all six components must be replaced whenever one rear control arm becomes worn. The correct repair scope should be based on professional inspection and the actual condition of the vehicle. Multiple rear control arms operate under similar mileage, environmental exposure and road conditions, so it is possible for several rubber-bushed components to show deterioration during the same inspection. Where several corresponding arms have developed excessive movement, cracked or separated bushes, impact damage or other significant deterioration, replacing the appropriate group together can provide a practical approach to a broader rear suspension refurbishment. This can also allow the suspension work to be completed before one final professional wheel-alignment check rather than repeatedly disturbing the rear suspension as additional worn components are identified. However, wear does not always develop uniformly. One arm may be damaged by a severe pothole or kerb strike while other components remain serviceable, or some arms may already have been replaced during earlier repairs. For that reason, each existing control arm and bush should be inspected individually. The technician should check for excessive movement, rubber deterioration, bush separation, corrosion, physical deformation and evidence of impact damage. Rear suspension mounting points should also be examined. Shock absorbers and springs should be inspected for their own condition, while wheel hubs, wheel bearings, wheels and tyres should be checked where relevant. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be assessed separately when knocking or rattling is present because replacing the control arms will not repair an unrelated stabilizer-link fault. The Stokes Germany package covers OEM references A1663500106, A1663500206, A1663500306 and A1663500053 and is specifically listed by JK Automotive as a Set of 6 for GLS X166 (2016–2020). Independent catalogue information indicates that A1663500306 and A1663500053 have left-and-right applications while A1663500106 and A1663500206 cover corresponding upper-left and upper-right applications, helping explain the six-piece package configuration. If professional inspection establishes that several of these corresponding arms require replacement and the package matches the vehicle, using the complete six-piece set can provide a coordinated solution. If the remaining components are confirmed serviceable, however, replacement decisions should remain condition-based rather than automatically replacing parts simply because they are available in a kit.
What should I check before buying the Mercedes-Benz GLS X166 Rear Lower And Upper Control Arm Complete Set of 6?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online should be purchased only after checking the vehicle model, chassis code, supplied year range, VIN, suspension configuration, exact OEM references, required installation positions and physical package quantity. First confirm that the vehicle is a Mercedes-Benz GLS X166 and that the required application corresponds with the supplied 2016–2020 range. JK Automotive currently lists this exact Stokes Germany product as a Rear Lower And Upper Control Arm Complete Set of 6 for Mercedes-Benz GLS X166 (2016–2020), using OEM references A1663500106 & A1663500206 & A1663500306 A1663500053. The listing also specifies a 6-month warranty against manufacturing defects. OEM-reference verification is important because suspension fitment can vary by model, production period and vehicle specification. Independent RIW catalogue data identifies A1663500106 as a rear upper-left control arm, A1663500206 as a rear upper-right control arm, A1663500306 as a rear lower-forward control arm used on both left and right sides and A1663500053 as another rear control arm used on both left and right sides for the X166 platform. This information also helps explain why four unique OEM-reference groups can correspond with a six-piece physical package. Before ordering, the vehicle's existing suspension should be professionally diagnosed. Do not assume that a knocking noise automatically means the complete control-arm package is required, because rear shock absorbers, springs, wheel bearings, wheels, tyres and stabilizer-system components can produce overlapping symptoms. If the existing control arms are accessible for identification, their OEM numbers should be compared with the supplied references. Where a different Mercedes-Benz number appears on the original component, the workshop should determine whether it is a superseded or alternative reference before ordering. Once the Set of 6 arrives, all six components should be laid out and matched directly with the corresponding original arms for geometry, length, mounting points, bush configuration and orientation before installation. Separate bolts, nuts and other mounting hardware should not be assumed to be included unless confirmed by the actual package. Professional installation should follow applicable Mercedes-Benz workshop procedures and vehicle-specific fastener specifications rather than generic or unverified torque values. Where the applicable workshop procedure requires final tightening of rubber-bushed suspension components at a defined suspension position or ride height, that procedure should be followed. Once all required rear suspension repairs have been completed correctly, professional wheel-alignment verification is strongly recommended.
What are the common symptoms of worn rear lower and upper control arms on Mercedes-Benz GLS X166?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online may be required when professional inspection identifies excessive movement, deteriorated bushes, physical deformation or other damage affecting multiple corresponding rear suspension control arms on the Mercedes-Benz GLS X166 (2016–2020). Rear control arms form part of the wheel-locating suspension system and help maintain the intended relationship between the rear wheel assemblies and suspension structure while allowing controlled movement as the vehicle travels over changing road surfaces. During normal operation, these components are repeatedly loaded under acceleration, braking, cornering and vertical suspension travel. With age, mileage and continuous suspension movement, rubber-to-metal bushes can deteriorate, crack, separate or permit excessive movement, while severe potholes, kerb impacts and other road shocks can potentially deform or damage an arm. Common symptoms that justify a professional rear suspension inspection include knocking or clunking noises over rough roads and speed breakers, unwanted movement from the rear of the vehicle, a less settled feeling when changing direction, inconsistent handling and irregular rear tyre wear. A worn control-arm bush may allow more movement than intended when the wheel is subjected to acceleration, braking or cornering forces, but these symptoms should not be used alone to conclude that all six control arms require replacement. Rear shock absorbers can produce poor damping or instability, springs can become damaged, wheel bearings can cause noise or unwanted movement, and wheel or tyre defects can create vibration and abnormal handling. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links are separate rear suspension components and can also produce knocking or rattling over uneven roads. A qualified technician should therefore inspect each relevant control arm individually, checking the bushes for excessive movement, cracking, separation or deformation and checking the arm itself for corrosion, impact marks or bending. Relevant rear suspension mounting points should also be inspected, particularly if the vehicle has suffered a significant road impact. The exact Stokes Germany package contains six physical components associated with OEM references A1663500106, A1663500206, A1663500306 and A1663500053. JK Automotive confirms this exact combination for its GLS X166 (2016–2020) product. Independent RIW data identifies A1663500106 as rear upper left, A1663500206 as rear upper right, A1663500306 as rear lower forward left and right, and A1663500053 as a rear left-and-right control-arm application. If several corresponding arms are confirmed worn, the Set of 6 can provide a coordinated replacement package. If only one component is defective and the remaining components are confirmed serviceable, the existence of a complete kit does not automatically mean all six must be replaced. The repair scope should follow diagnosis, and professional wheel-alignment verification is strongly recommended after the necessary suspension work.
Which OEM numbers and rear suspension positions are covered by the Mercedes-Benz GLS X166 Rear Control Arm Complete Set of 6?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online from Stokes Germany covers the exact OEM references A1663500106, A1663500206, A1663500306 and A1663500053 and is supplied as a physical Set of 6 for Mercedes-Benz GLS X166 (2016–2020). JK Automotive confirms the four OEM-reference groups, six-piece package, Stokes Germany brand and GLS X166 application. Independent suspension catalogue information provides a useful technical explanation of how four unique references can correspond with six physical control arms. RIW identifies A1663500106 as a rear upper-left control arm and A1663500206 as a rear upper-right control arm. The same catalogue identifies A1663500306 as a rear lower-forward control arm suitable for both left and right positions and A1663500053 as another rear control arm suitable for both left and right positions. This means the package structure can logically account for six physical components: one left-side A1663500106 application, one right-side A1663500206 application, two A1663500306 applications covering the left and right rear lower-forward positions and two A1663500053 applications covering corresponding left and right positions. Teknorot independently identifies A1663500306 as a rear-forward lateral arm and specifies a quantity of two per vehicle, providing additional support for the two-piece application of this reference. For A1663500053, independent catalogue data lists the component for the rear axle, both sides, with a required quantity of two; another listing describes it as a rear upper arm with rubber mounting. This is an important point for product information because a six-piece package does not require six unique OEM numbers. No extra OEM reference should be invented simply to make the OEM-number count equal the physical quantity. Suspension terminology can also differ between manufacturers and catalogues. For example, A1663500306 may be described as a control arm, lateral arm, track control arm or trailing arm depending on the source, while Gepard describes it as a rear lower-forward track control arm. Consequently, the exact OEM reference, installation position, physical component and vehicle specification should be considered together rather than relying only on a generic part name. Before installation, all six Stokes Germany components should be arranged and matched directly with their corresponding original GLS X166 suspension arms. The technician should compare geometry, overall dimensions, mounting locations, bush configuration and orientation. If an original arm carries another Mercedes-Benz number, the workshop should determine whether it is a valid supersession or alternative reference before fitting the replacement. VIN and OEM-reference verification are recommended before ordering, and the actual Stokes Germany package should remain the final reference for the six physical components supplied.
What other suspension components should be inspected when replacing the rear control arm Set of 6 on Mercedes-Benz GLS X166?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online should ideally be installed as part of a complete rear suspension inspection because replacing six lower and upper control-arm components will not correct a problem caused by another worn or damaged suspension, wheel or tyre component. Before replacement, every relevant existing control arm and its bushes should be inspected individually for excessive movement, rubber cracking, separation, deformation, corrosion and impact damage. The mounting points where these components connect to the suspension structure should also be examined, especially when the vehicle has previously suffered a severe pothole impact, kerb strike or accident. Rear shock absorbers should be inspected for visible leakage, physical damage and abnormal damping behaviour, while rear springs should be examined for physical condition and damage. Wheel hubs and wheel bearings should be checked when symptoms include humming, roughness, vibration or unwanted wheel movement. Rear wheels should be inspected for impact-related deformation where appropriate, while tyres should be checked for pressure, tread condition, cuts, bulges and irregular wear. Abnormal tyre wear can be evidence that suspension condition or wheel geometry requires attention, but tyre wear by itself cannot identify which particular control arm is defective. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected because these are separate components capable of producing knocking or rattling that can be confused with worn control-arm bushes. RIW's X166 catalogue, for example, separately lists a rear left-and-right stabilizer link in addition to the control arms, confirming that the stabilizer link is not the same component as the arms represented by A1663500106, A1663500206, A1663500306 and A1663500053. Stabilizer bushes and mounting points should therefore also be examined when appropriate. Brake hoses, ABS sensor wiring and nearby cables should be protected during suspension disassembly and checked if their routing or mounting has been disturbed. Once diagnosis is complete, all six Stokes Germany replacement components should be compared directly with the corresponding original arms before installation. JK Automotive lists the product as a Set of 6 for GLS X166 (2016–2020), covering A1663500106, A1663500206, A1663500306 and A1663500053. RIW identifies A1663500306 as a rear lower-forward left-and-right component and A1663500053 as a rear left-and-right arm, while A1663500106 and A1663500206 cover the corresponding upper-left and upper-right positions. If another substantially worn component is discovered during disassembly, completing that necessary repair before the final wheel alignment can avoid disturbing the suspension again. This does not mean that every related suspension component should automatically be replaced. Each component should be assessed according to its actual condition and the manufacturer's service requirements. After all required mechanical repairs are completed correctly, professional wheel-alignment verification is strongly recommended.
Is wheel alignment necessary after replacing the Mercedes-Benz GLS X166 Rear Lower And Upper Control Arm Complete Set of 6?
Mercedes-Benz GLS X166 Rear Control Arm Complete Set Online replacement should be followed by professional wheel-alignment verification because the Stokes Germany Set of 6 contains multiple rear suspension arms involved in locating and controlling the rear wheel assemblies. Rear suspension geometry depends on the relationship between wheel-locating components, mounting points and the wheel hub assembly, so replacing multiple control arms and their bushes can affect the vehicle's final wheel position relative to its previous worn condition. If old control-arm bushes have developed excessive movement, the wheel may have been moving outside its intended relationship under acceleration, braking or cornering loads. Replacing the worn components restores serviceable mounting points, but the resulting geometry should still be checked using professional alignment equipment. Before alignment, the mechanical repair must be completed correctly. The replacement components should be verified using Mercedes-Benz GLS X166, the supplied 2016–2020 application, VIN where appropriate and OEM references A1663500106, A1663500206, A1663500306 and A1663500053. JK Automotive confirms this exact reference group as its Stokes Germany GLS X166 Set of 6. Independent catalogue data identifies the references across upper-left, upper-right, lower-forward left-and-right and additional left-and-right rear control-arm applications, confirming that several wheel-locating components are involved in this package. The workshop should inspect the relevant mounting locations before installation, and wheel bearings, wheels and tyres should be checked where their condition could interfere with diagnosis or alignment. Rear shock absorbers, springs and stabilizer-system components should also be inspected as necessary. All six new components should be compared physically with their corresponding originals before fitting. Installation should follow the applicable Mercedes-Benz workshop procedure and vehicle-specific fastener specifications rather than generic or unverified torque values. Where the applicable workshop procedure requires final tightening of rubber-bushed suspension components at a defined suspension position or ride height, that procedure should be followed. Once installation is complete and all relevant suspension components are confirmed serviceable, the vehicle should undergo professional wheel-alignment verification using the correct specification for its configuration. If a geometry measurement remains outside specification, the technician should investigate the mechanical cause rather than attempting to compensate for an incorrect arm, bent component or damaged mounting point purely through alignment adjustment. Tyre condition should also be considered because severe irregular wear caused before the repair will not disappear merely because the suspension has been corrected. For a comprehensive six-piece rear control-arm replacement, wheel-alignment verification is therefore an important final stage of the repair and can help confirm that the GLS X166 wheel geometry is within the applicable specification after the new suspension components have been installed.
