Mercedes-Benz GLC X253 Front Upper Control Arms are important front suspension components that help guide the wheel assemblies and maintain controlled suspension movement as the vehicle travels over different road surfaces, and this LEMFORDER set of 2 includes part numbers 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 for the specified application when these references match the individual vehicle. The upper control arms form part of the suspension connection between the wheel-side assemblies and the vehicle chassis, helping each front wheel move through its designed suspension path while limiting unwanted movement. During everyday driving, the suspension is continuously working even when the road appears smooth. Small road irregularities create constant suspension movement, while potholes, broken roads and speed breakers generate larger forces through the control arms, bushes, joints and mounting points. Braking transfers vehicle weight towards the front axle, increasing the load acting through the suspension system, while cornering creates lateral forces through the tyres and wheel assemblies. The upper arms therefore work together with lower control arms, thrust control arms, suspension bushes, ball joints, steering tie rod ends, shock absorbers, springs and wheel bearings to support controlled wheel positioning. When an upper-arm bush, joint or mounting area develops excessive wear, the wheel assembly may have more movement than intended. Depending on the actual fault, this can contribute to knocking or clunking noises, steering vibration, vague steering response, reduced directional stability or uneven tyre wear. The vehicle may also feel less settled when travelling over uneven roads or during changes in direction. These symptoms should not automatically be treated as proof that an upper control arm has failed because several related components can create similar problems. Lower control arms and thrust arms should be inspected for worn bushes, while steering tie rod ends and ball joints should be checked for excessive play. Shock absorbers should be examined for leakage, damage and reduced damping performance. Wheel bearings should be checked when noise, vibration or excessive wheel movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected if knocking or rattling occurs over rough roads. If professional diagnosis confirms that the upper arms require replacement, verify LEMFORDER 39369 01 and 39368 01 together with OEM A2053305501 / A2053305601 against the VIN and original components before ordering. Professional installation followed by a wheel alignment check is recommended.

LEMFORDER 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 are supplied in this Mercedes-Benz GLC X253 Front Upper Control Arms set of 2, but exact compatibility should always be confirmed against the vehicle VIN, original suspension components and required part references before purchase because the GLC X253 model designation alone may not identify every suspension configuration used across all vehicles. Suspension specifications can vary according to production configuration, engine, drivetrain, suspension package and other vehicle equipment, so correct part-number verification is especially important when ordering control arms. Customers should compare LEMFORDER references 39369 01 and 39368 01 and OEM references A2053305501 / A2053305601 with the parts required for their individual Mercedes-Benz GLC X253. Visual appearance alone should not be used to determine compatibility because two suspension arms can look similar while having differences in dimensions, mounting points, bush design, joint arrangement or intended installation position. Correctly matched upper control arms help guide the front wheel assemblies as the suspension moves and help maintain controlled wheel positioning relative to the chassis. These components experience continuous mechanical loads whenever the vehicle is driven. Normal roads create repeated small movements, while potholes and speed breakers produce larger impact loads. Braking increases loading through the front suspension, while cornering generates lateral forces through the tyres and wheel assemblies. Over time, bushes and associated components may deteriorate and develop unwanted movement. Worn upper arms can contribute to knocking, steering vibration, vague handling or irregular tyre wear, although similar symptoms can originate elsewhere in the suspension or steering system. Lower control arms, thrust arms, steering tie rod ends, ball joints, shock absorbers and wheel bearings should therefore be inspected during diagnosis. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be checked if suspension noise occurs. Tyre pressure, tyre condition, wheel balancing and alignment should be considered when diagnosing vibration or uneven tyre wear. If the upper arms are confirmed as worn and the supplied references match the vehicle, this LEMFORDER set can be considered for replacement. VIN and part-number verification before ordering, professional installation and a wheel alignment check after replacement are recommended.

This Mercedes-Benz GLC X253 Front Upper Control Arms package contains a set of 2 because it supplies the corresponding upper suspension arms represented by LEMFORDER 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601, making it convenient to purchase the relevant pair together when both corresponding components have been professionally diagnosed as requiring replacement. The front suspension contains components operating on both sides of the vehicle, and each control arm must be installed in its correct intended suspension position. Both front suspension sides generally experience the same overall vehicle mileage, but this does not mean they always wear at exactly the same rate. One side may encounter more potholes, damaged road surfaces, road-edge impacts or previous suspension repairs than the other. When both corresponding upper-arm bushes, joints or mounting areas show significant deterioration, replacing the pair during the same repair can bring those affected suspension components to a more consistent mechanical condition. New correctly matched upper arms can remove unwanted movement caused by the diagnosed worn components and help the suspension maintain controlled wheel positioning. Purchasing a complete set of 2 also simplifies parts selection when both upper suspension arms are required because LEMFORDER 39369 01 and 39368 01 are supplied together rather than requiring separate purchasing. However, the set-of-2 format does not mean that both components must automatically be replaced whenever one arm develops an isolated fault. If one component has been damaged by a severe road impact while the corresponding arm remains in serviceable condition, a technician should determine the appropriate repair after inspection. The remaining front suspension components should also be checked because upper arms work as part of a complete system. Lower control arms and thrust arms should be inspected for bush deterioration. Ball joints and steering tie rod ends should be checked for excessive play. Shock absorbers should be examined for leakage or reduced damping performance, while wheel bearings should be inspected when noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected if the vehicle has suspension rattling or knocking. Tyres should be checked for abnormal wear that may indicate previous suspension or alignment problems. Before ordering this set, verify LEMFORDER 39369 01 and 39368 01 and OEM A2053305501 / A2053305601 against the VIN and original suspension parts. When both corresponding upper arms are confirmed as worn, replacing the pair followed by a professional wheel alignment check provides a comprehensive approach to the diagnosed repair.

Common symptoms associated with worn Mercedes-Benz GLC X253 Front Upper Control Arms can include knocking or clunking from the front suspension, steering vibration, vague or loose steering response, reduced directional stability, unusual suspension movement and uneven tyre wear, although these symptoms can have several different causes and should be professionally diagnosed before replacing LEMFORDER 39369 01 and 39368 01 or components identified through OEM references A2053305501 / A2053305601. Upper control arms and their bushes, joints and mounting areas experience repeated mechanical loads whenever the vehicle is driven. Normal roads create continuous small suspension movements, while potholes, damaged roads and speed breakers create larger movements and stronger impact forces. Braking transfers additional vehicle weight towards the front axle, while cornering produces lateral forces through the tyres and suspension components. Over time, rubber bushes can harden, crack, deform or separate, while joints or mounting points may develop excessive movement. A worn component can allow the wheel assembly to move beyond its intended range, which may produce knocking or clunking as the suspension travels over road irregularities. Steering may begin to feel less precise if unwanted suspension movement becomes significant. Some drivers may notice vibration through the steering wheel, while others may notice that the vehicle feels less settled during braking, cornering or changes in direction. Irregular tyre wear may also develop when suspension deterioration contributes to changes in wheel geometry. However, uneven tyre wear alone does not prove that an upper control arm has failed. Lower control arms and thrust control arms can produce similar symptoms when their bushes deteriorate. Steering tie rod ends and ball joints should be checked for excessive play. Shock absorbers should be inspected for leakage, physical damage and reduced damping performance. Wheel bearings should be examined when noise, vibration or wheel movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links can create knocking or rattling over uneven roads and should therefore be inspected during diagnosis. Tyres should be checked for correct pressure, physical damage and tread condition, while wheel balancing should be considered if vibration mainly appears at certain vehicle speeds. If professional inspection confirms wear in the corresponding upper arms, verify LEMFORDER 39369 01 and 39368 01 together with OEM A2053305501 / A2053305601 against the VIN before ordering. Professional installation and a wheel alignment check are recommended after replacement.

Replacing Mercedes-Benz GLC X253 Front Upper Control Arms as a complete LEMFORDER set of 2 can be beneficial when professional inspection confirms significant wear in both corresponding upper suspension components because the package combines LEMFORDER 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 into one convenient set when these references match the vehicle. Both sides of the front suspension generally experience the same total vehicle mileage and many of the same driving conditions, although the exact rate of wear can differ according to pothole impacts, road quality, driving conditions and previous repairs. When both upper-arm bushes, joints or mounting areas have deteriorated, replacing the corresponding pair during the same repair can bring those affected components to a more consistent condition. Correctly matched new upper arms can remove unwanted movement caused by the worn components and help maintain controlled wheel positioning. This may help address knocking, steering vibration, vague handling or reduced directional stability when deteriorated upper arms have been confirmed as the cause. Purchasing both corresponding components together can also simplify the repair process by reducing the need to source each arm separately. However, replacing a pair should be based on inspection rather than being treated as mandatory whenever only one arm is damaged. One component may suffer isolated impact damage while the opposite side remains mechanically serviceable. The entire front suspension should therefore be inspected before deciding which parts require replacement. Lower control arms and thrust arms should be checked for bush wear. Steering tie rod ends and ball joints should be examined for excessive movement. Shock absorbers should be inspected for leakage, damage or reduced damping, while wheel bearings should be checked if unusual noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when suspension noise occurs. Tyres should be examined for irregular wear because previous suspension movement or incorrect wheel geometry may already have affected the tread. Before ordering, verify LEMFORDER 39369 01 and 39368 01 and OEM A2053305501 / A2053305601 against the vehicle VIN and original components. When both corresponding upper arms are confirmed as worn, replacing the complete set followed by a professional wheel alignment check provides a practical approach to the suspension repair.

LEMFORDER 39369 01 and 39368 01 can be considered when replacing Mercedes-Benz GLC X253 Front Upper Control Arms if these LEMFORDER references and OEM A2053305501 / A2053305601 match the individual vehicle, because LEMFORDER is an established steering and suspension component brand and this product conveniently provides the corresponding upper suspension components together as a set of 2; however, correct fitment, part-number verification, component condition and professional installation should remain the main considerations when choosing any replacement suspension arm. Upper control arms help guide wheel movement, which means correct dimensions, mounting geometry, bush configuration and intended installation position are important. Customers should therefore verify LEMFORDER 39369 01 and 39368 01 together with OEM A2053305501 / A2053305601 against the VIN and original parts rather than purchasing only according to the GLC X253 model designation or the visual appearance of the components. When worn upper-arm bushes, joints or mounting areas are professionally diagnosed as the source of excessive movement, installing correctly matched replacements can remove unwanted movement caused by those deteriorated components. This may help address knocking, vague steering or reduced road stability when the upper arms are confirmed as the source of the symptoms. The complete front suspension should still be inspected because new upper control arms cannot repair unrelated wear elsewhere in the system. Lower control arms and thrust arms should be checked for deteriorated bushes. Steering tie rod ends and ball joints should be inspected for excessive play. Shock absorbers should be checked for leakage, physical damage and reduced damping performance, while wheel bearings should be examined when noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be checked if the vehicle produces knocking or rattling over uneven roads. Tyres should be inspected for correct pressure, physical condition and irregular wear. For customers specifically searching for these LEMFORDER suspension references, this set combines 39369 01 and 39368 01 with OEM A2053305501 / A2053305601 when both corresponding upper suspension arms are required. Verify the VIN and original part references before ordering, have the components installed professionally in their intended positions, and complete a wheel alignment check after replacement to help maintain correct suspension geometry, predictable steering, stable road handling and balanced tyre wear.

Mercedes-Benz GLC X253 Front Upper Control Arms are important parts of the front suspension because they help guide the front wheel assemblies through their intended suspension movement while supporting controlled steering, predictable handling and stable road behaviour, and this LEMFORDER set contains part numbers 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 for compatible applications. The upper control arms connect important areas of the wheel-side suspension to the chassis and help maintain the position of the wheel as the suspension moves vertically over different road surfaces. Every time the Mercedes-Benz GLC X253 travels over a small road imperfection, pothole, speed breaker or broken section of road, the suspension must allow the wheel to move while keeping that movement properly controlled. The upper arms work together with lower control arms, thrust control arms, suspension bushes, ball joints, steering tie rod ends, shock absorbers, springs and wheel bearings to maintain the designed movement of the front suspension. During braking, additional vehicle load transfers towards the front axle, increasing the forces acting through these suspension components. During cornering, lateral forces generated at the tyres are transferred through the wheel assemblies and suspension links, making correct control-arm condition important for consistent wheel guidance. If the bushes, joints or mounting areas of an upper control arm become excessively worn, the wheel assembly may develop unwanted movement. Depending on the exact component and severity of wear, the driver may notice knocking or clunking over uneven roads, steering vibration, vague steering response, reduced straight-line stability or irregular tyre wear. The GLC may also feel less settled when braking or changing direction if suspension play becomes significant. These symptoms should always be diagnosed properly because upper control arms are not the only components capable of producing them. Lower control arms and thrust arms can create similar problems when their bushes deteriorate. Ball joints and steering tie rod ends can contribute to excessive wheel movement or steering looseness. Worn shock absorbers can reduce suspension control, while wheel bearings may cause noise, vibration or play. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when knocking or rattling is present. Correct tyre pressure, tyre condition, wheel balancing and alignment should also be considered during diagnosis. If inspection confirms worn upper control arms, correctly matched LEMFORDER 39369 01 and 39368 01 can be considered when OEM A2053305501 / A2053305601 correspond with the vehicle. Verify the VIN and OE references before ordering, and complete a professional wheel alignment check after installation.

A professional wheel alignment check is recommended after replacing Mercedes-Benz GLC X253 Front Upper Control Arms because these components form part of the suspension linkage that helps determine and control the position of the front wheel assemblies relative to the vehicle chassis, and replacement of LEMFORDER 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 involves components directly associated with front suspension geometry. When old upper control-arm bushes, joints or mounting areas become worn, they can allow unwanted movement of the wheel assembly under braking, cornering or road impact. This movement may contribute to changes in wheel positioning and can result in vague steering, instability or abnormal tyre wear. Installing correctly matched new upper control arms removes excessive movement caused by the diagnosed worn components, but fitting new parts does not automatically confirm that the vehicle's wheel geometry is within the correct specification. A professional alignment check allows the workshop to measure the suspension after the repair and identify whether alignment adjustment is required. Correct wheel geometry helps support straight-line stability, predictable steering response and even tyre wear. Incorrect geometry can contribute to the vehicle pulling towards one side, an off-centre steering wheel or excessive wear on the inner or outer edges of the tyres. Before completing alignment, other suspension and steering components should also be inspected because excessive play elsewhere can affect accurate measurement. Lower control arms and thrust control arms should be checked for worn bushes. Steering tie rod ends should be inspected because they are directly involved in wheel direction and steering adjustment. Ball joints and suspension bushes should be examined for excessive movement. Shock absorbers should be checked for leakage, physical damage and reduced damping performance. Wheel bearings should also be inspected when unusual noise, vibration or wheel movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be examined if suspension knocking or rattling is present, although these components perform a different function from wheel alignment. Tyres should have the correct pressure and should be inspected for existing uneven wear. Wheel balancing should be considered separately if vibration mainly occurs at particular speeds. Before installation, verify LEMFORDER 39369 01 and 39368 01 and OEM A2053305501 / A2053305601 against the VIN and original parts. After the replacement has been completed correctly, a professional alignment check is a sensible final step to help maintain controlled steering, suspension geometry and balanced tyre wear.

Worn Mercedes-Benz GLC X253 Front Upper Control Arms can contribute to progressively increasing suspension noise, unwanted wheel movement, steering vibration, vague handling, reduced directional stability and irregular tyre wear when deteriorated bushes, joints or mounting areas remain in service, although the exact symptoms and severity depend on the specific component that is worn. This LEMFORDER replacement set contains 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 for compatible applications, and the correct references should be verified before replacement. Upper control arms operate continuously whenever the vehicle is moving. Even on smooth roads, the front suspension makes small movements as the tyres follow changes in the road surface. Potholes, damaged roads and speed breakers create much larger suspension movements and impact forces. Braking transfers vehicle weight towards the front axle, while cornering creates lateral forces through the tyres, wheel assemblies and suspension links. Repeated loading can gradually deteriorate rubber bushes and associated components. Bushes can harden, crack, deform or separate, while joints and mounting areas can develop excessive play. Early wear may produce only an occasional knocking sound or a small change in steering feel. As deterioration progresses, the suspension may allow greater unwanted wheel movement, which can contribute to clunking over rough roads, steering vibration or reduced confidence in straight-line stability. Irregular tyre wear can also occur if suspension wear contributes to changes in wheel geometry, potentially reducing the useful life of expensive tyres. However, replacing upper arms without diagnosis is not recommended because similar symptoms can come from other parts of the front axle. Lower control arms and thrust arms should be checked for bush wear. Ball joints and steering tie rod ends should be examined for excessive movement. Shock absorbers should be checked for leakage, physical damage and damping condition. Wheel bearings should be inspected when noise, vibration or wheel play is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links can also create knocking or rattling over uneven surfaces. Tyre pressure, tyre condition, wheel balancing and alignment should therefore form part of a complete diagnosis where appropriate. If inspection confirms that the corresponding upper arms are worn, replacement with correctly matched components can help remove the excessive movement caused by those parts. Verify LEMFORDER 39369 01 and 39368 01 together with OEM A2053305501 / A2053305601 against the VIN before ordering, and complete professional installation followed by a wheel alignment check.

Replacing both Mercedes-Benz GLC X253 Front Upper Control Arms together can be beneficial when professional inspection confirms significant wear in both corresponding suspension components because the left and right suspension systems generally experience the same overall vehicle mileage, and this LEMFORDER package conveniently provides 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 as a set of 2 for compatible applications. LEMFORDER 39369 01 is listed as a front-axle right upper control arm and is paired with 39368 01, supporting their use as corresponding components when the application and OE references match the vehicle. Although both front suspension sides normally cover the same total distance, the components may not wear at exactly the same rate. One side may encounter more potholes, damaged road surfaces, road-edge impacts or previous suspension repairs. Therefore, both arms should not automatically be replaced simply because one component is damaged. The correct decision should be based on inspection of the bushes, joints, arm structure and mounting areas. When both corresponding upper arms show significant wear, replacing the pair during the same repair can bring those affected suspension components to a more consistent condition. It may also reduce the likelihood of replacing one heavily worn arm and then needing another similar repair shortly afterwards because the opposite arm was already significantly deteriorated. Correctly matched new arms can remove unwanted movement caused by the worn components and help maintain controlled wheel positioning. This can help address knocking, vague steering or instability when the upper arms are confirmed as the source of those symptoms. Purchasing the pair together also simplifies parts selection when both corresponding components are required. However, new upper arms cannot repair unrelated problems elsewhere in the suspension. Lower control arms and thrust arms should be checked for bush deterioration. Steering tie rod ends and ball joints should be inspected for play. Shock absorbers should be checked for leakage and damping condition, while wheel bearings should be examined if unusual noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be checked if knocking occurs. Tyres should be inspected for abnormal wear because previous suspension movement or incorrect geometry may already have affected the tread. Verify LEMFORDER 39369 01 and 39368 01 and OEM A2053305501 / A2053305601 against the VIN before ordering. When both arms are confirmed as worn, pair replacement followed by professional wheel alignment provides a comprehensive approach to the diagnosed repair.

LEMFORDER can be considered a premium suspension-component choice when purchasing Mercedes-Benz GLC X253 Front Upper Control Arms because it is an established steering and chassis brand associated with ZF, while this particular set combines LEMFORDER 39369 01 and 39368 01 with OEM references A2053305501 / A2053305601 for compatible applications; however, a fair comparison with FEBI, Meyle, TRW and other established suspension brands should be based on verified fitment, component design, materials, specification, warranty, availability, price and after-sales support rather than assuming that every component from one manufacturer is automatically better than every competing product. For this application, available catalogue information identifies 39369 01 as an aluminium front-axle right upper control arm paired with 39368 01, while 39368 01 cross-references Mercedes-Benz A2053305501 and 39369 01 cross-references A2053305601. The X253 is also specifically included among compatible Mercedes-Benz platforms in available catalogues. Correct compatibility should remain the first consideration when selecting any suspension component. Replacement arms from LEMFORDER, FEBI, Meyle, TRW and other established manufacturers can serve similar vehicle applications while differing in construction details, bush design, joint configuration, corrosion protection, supplied hardware, warranty conditions and pricing. This makes technical specification and correct OE cross-reference more useful buying criteria than appearance or price alone. Customers considering this LEMFORDER set should first verify 39369 01 and 39368 01 and OEM A2053305501 / A2053305601 against the vehicle VIN and original components. A premium replacement arm also cannot compensate for worn parts elsewhere in the suspension. Lower control arms, thrust arms, ball joints and steering tie rod ends should be inspected for wear or excessive play. Shock absorbers should be checked for leakage and damping condition, while wheel bearings should be examined if noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when knocking or rattling occurs. Tyres should be checked for correct pressure and abnormal tread wear. For customers specifically searching for these LEMFORDER references, the set provides the corresponding upper suspension components together when both are required and confirmed compatible. The final buying decision should consider correct OE references, VIN compatibility, product specification, warranty, availability, price and supplier support. Professional installation followed by a wheel alignment check is recommended to help maintain correct suspension geometry, stable steering, predictable road handling and even tyre wear.
