What are LEMFORDER Front Upper & Lower Control Arms for Audi Q5 8R and what is their function?
Audi Q5 8R Front Upper & Lower Control Arms are important components of the vehicle’s front multi-link suspension system that help guide the front wheels through controlled suspension movement while supporting stable steering, predictable handling and correct wheel positioning, and this complete LEMFORDER set of 8 includes part numbers 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. The Audi Q5 8R uses several individual suspension links at the front axle rather than depending on one simple control arm on each side, which means different upper and lower arms work together to control the position and movement of each front wheel. Available catalogue information identifies 35685 01 and 35686 01 as corresponding upper-front arms, 35687 01 and 35688 01 as corresponding upper-rear arms, 37486 01 and 37487 01 as corresponding lower-front arms, while 38964 01 and 38965 01 form the corresponding lower-rear pair. Each component therefore has a specific position within the suspension and should not be treated as interchangeable. During normal driving, these arms continuously move as the wheels follow changes in the road surface. Potholes, speed breakers and damaged roads generate larger forces through the arms, bushes, ball joints and mounting areas. During braking, vehicle weight transfers towards the front axle and increases suspension loading, while cornering produces lateral forces through the tyres and wheel assemblies. Correctly functioning control arms help manage these movements while supporting controlled suspension geometry. As bushes or joints deteriorate, unwanted wheel movement can develop and may contribute to knocking, clunking, steering vibration, vague steering response, reduced road stability or uneven tyre wear. The complete front suspension should therefore be inspected whenever these symptoms occur because steering tie rod ends, shock absorbers, wheel bearings and other suspension parts may produce similar symptoms. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be checked when rattling or knocking is present. Before ordering, verify all eight LEMFORDER references and OEM numbers against the vehicle VIN and original components. Professional installation and a wheel alignment check are recommended after replacement.
Are LEMFORDER 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 suitable for Audi Q5 8R?
LEMFORDER 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 are supplied in this Audi Q5 8R Front Upper & Lower Control Arms set of 8, and the supplied product listing identifies the complete kit for Audi Q5 8R 2008–2017 with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. Exact compatibility should nevertheless be checked against the individual vehicle VIN, original suspension components and required part numbers before purchase because vehicle configuration and suspension specifications can vary. Correct verification is especially important with a complete multi-link suspension kit because every arm has a specific installation position. For example, catalogue data identifies 37486 01 as front axle left lower front and 37487 01 as front axle right lower front, while 35685 01 is front axle left upper front and 35686 01 is front axle right upper front. The corresponding 35687 01 and 35688 01 are listed for the left and right upper-rear positions respectively. This position-specific arrangement means visual similarity alone should never be used to confirm compatibility. Correctly matched suspension arms help guide wheel movement while supporting controlled steering and suspension geometry. When bushes, joints or mounting areas develop excessive wear, drivers may notice knocking over uneven roads, steering vibration, loose handling, reduced directional stability or irregular tyre wear. However, these symptoms can originate from several components. Steering tie rod ends should be checked for excessive play, shock absorbers should be inspected for leakage or reduced damping, and wheel bearings should be checked when noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when suspension rattling occurs. Tyre condition, tyre pressure, wheel balancing and alignment should be checked where appropriate. If professional inspection confirms that the corresponding upper and lower suspension arms require replacement, this complete LEMFORDER set provides the eight listed components together. Verify the VIN, LEMFORDER references and OEM numbers before ordering, followed by professional installation and wheel alignment.
Why does this Audi Q5 8R Front Upper & Lower Control Arms kit contain a set of 8?
This Audi Q5 8R Front Upper & Lower Control Arms kit contains a set of 8 because the Audi Q5 8R front multi-link suspension uses several separate suspension arms around the left and right front wheel assemblies, and the package combines the corresponding upper-front, upper-rear, lower-front and lower-rear arms into one comprehensive replacement set. The kit contains LEMFORDER 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 together with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. Catalogue information confirms that these LEMFORDER numbers represent different left/right and upper/lower positions rather than eight identical arms. This arrangement allows several suspension links to work together to guide the front wheel through its intended movement as the suspension compresses and extends. The benefit of purchasing a complete set becomes particularly relevant when professional inspection identifies substantial wear across several corresponding control arms. Because the components operate through the same vehicle mileage and are exposed to similar road conditions, multiple bushes and joints may eventually require attention, although they do not necessarily wear at exactly the same rate. One side may experience more potholes, damaged roads or previous impact damage than the other. Therefore, the existence of an eight-piece kit does not mean all eight arms must automatically be replaced whenever one component develops a fault. Each suspension arm should be inspected individually. When the complete corresponding group is significantly worn, replacing the diagnosed arms during one repair can bring those components to a more consistent mechanical condition and may reduce the need for repeated suspension dismantling as other already-worn arms subsequently require replacement. New correctly matched arms can remove unwanted movement caused by worn bushes and joints and help restore controlled wheel guidance. Other components should still be checked, including steering tie rod ends, shock absorbers and wheel bearings. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be inspected when suspension noise is present. Verify all eight LEMFORDER numbers, OEM references and the VIN before ordering, and complete professional wheel alignment after installation.
What are the common symptoms of worn upper and lower control arms on an Audi Q5 8R?
Common symptoms of worn Audi Q5 8R Front Upper & Lower Control Arms can include knocking or clunking from the front suspension, rattling over rough roads, steering vibration, vague or loose steering response, reduced directional stability, unusual movement during braking and uneven tyre wear, although these symptoms should always be professionally diagnosed because several suspension, steering, wheel and tyre components can produce similar problems. The Q5 8R front suspension uses multiple links, which means wear can develop in the upper-front, upper-rear, lower-front or lower-rear suspension arms, and the symptoms can vary depending on which bushes, joints or mounting areas have deteriorated. This complete LEMFORDER kit contains 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 for the corresponding suspension positions when the supplied references match the vehicle. Rubber bushes within suspension arms are repeatedly compressed and twisted as the wheels travel over changing road surfaces. With mileage and use, bushes can deteriorate, crack, deform or develop excessive movement, while ball-joint areas and other suspension connections may also develop wear. Early deterioration may produce only an occasional knocking sound when crossing a pothole or speed breaker. As wear progresses, the front suspension may develop more noticeable movement and the driver may experience reduced steering precision or vibration. If suspension wear affects wheel positioning, abnormal tyre wear may also develop on the inner or outer sections of the tread. Braking can make some symptoms more noticeable because additional vehicle weight is transferred towards the front axle. However, knocking does not automatically indicate a worn control arm. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links can produce similar noises over uneven roads. Steering tie rod ends can create looseness or play, shock absorbers can reduce suspension control when their damping performance deteriorates, and wheel bearings can produce noise or vibration. Wheel balancing and tyre condition should also be considered when diagnosing steering vibration. A complete suspension inspection is therefore important before purchasing an eight-piece kit. If several or all corresponding arms are confirmed as worn, verify LEMFORDER 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 together with the supplied OEM references against the VIN before replacement.
What are the benefits of replacing Audi Q5 8R Front Upper & Lower Control Arms as a complete set of 8?
Replacing Audi Q5 8R Front Upper & Lower Control Arms as a complete LEMFORDER set of 8 can provide a comprehensive repair approach when professional inspection confirms significant wear across the corresponding front suspension links, because the package groups 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 together rather than requiring each suspension arm to be sourced individually. The supplied OEM references are 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M, and the product is listed for Audi Q5 8R 2008–2017. Because the Audi front multi-link system uses several separate links, deterioration may be present in multiple bushes or joints after extended use. When all corresponding arms are significantly worn, replacing the complete diagnosed group during one workshop visit can bring these suspension components to a more consistent condition. Correctly matched new suspension arms can remove excessive movement caused by deteriorated bushes, joints or mounting areas and help maintain controlled wheel guidance. This may help address knocking, vague steering, reduced road stability or abnormal tyre wear when those symptoms have been correctly traced to the worn arms. A complete set can also simplify parts sourcing and workshop planning because the relevant upper and lower links are grouped together. However, replacing eight arms should not be treated as mandatory when only one or two components have an isolated fault and the remaining parts are serviceable. The decision should be based on physical inspection and measured play. Other front axle components should also be examined because new control arms cannot correct unrelated faults. Steering tie rod ends should be checked for play, shock absorbers for leakage or poor damping, and wheel bearings for noise or excessive movement. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected. Tyres should be checked for abnormal wear that may have developed while the old suspension components were deteriorated. When the complete group genuinely requires replacement, fitting the correctly matched set followed by professional wheel alignment provides a comprehensive approach to the affected front suspension.
Why choose this LEMFORDER set of 8 for Audi Q5 8R front suspension replacement?
Why are Audi Q5 8R Front Upper & Lower Control Arms important for suspension, steering and road stability?
Audi Q5 8R Front Upper & Lower Control Arms are important parts of the front multi-link suspension because they help guide the front wheel assemblies through their intended movement while supporting stable steering, controlled suspension geometry and predictable road handling. This complete LEMFORDER set of 8 contains 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. Unlike a simple suspension arrangement with only one major arm on each side, the Audi Q5 8R uses several individual suspension links around each front wheel. The upper and lower control arms therefore work together rather than operating as isolated components. Catalogue information identifies 38965 01 as a right lower rear arm paired with 38964 01, 37487 01 as a right lower front arm paired with 37486 01, and 35685 01 as a left upper front arm paired with 35686 01, illustrating the position-specific design of this suspension system. During normal driving, the wheels continuously move as the tyres follow changes in the road surface. Potholes, broken roads, speed breakers and uneven surfaces create larger movements and stronger forces through the suspension links, bushes and joints. During braking, additional vehicle weight transfers towards the front axle, while cornering generates lateral forces through the tyres and wheel assemblies. Correctly functioning upper and lower arms help control these movements and keep the wheel assemblies moving through their intended suspension path. When bushes, joints or mounting areas become worn, unwanted wheel movement can develop. Depending on the location and severity of wear, the driver may notice knocking, clunking, steering vibration, vague steering response, reduced straight-line stability or irregular tyre wear. The vehicle may also feel less controlled during braking or when travelling over uneven roads. These symptoms should be professionally diagnosed because other components can produce similar problems. Steering tie rod ends, shock absorbers and wheel bearings should also be inspected. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be checked when rattling or knocking is present. Tyres should be examined for uneven wear and correct pressure. When multiple corresponding suspension arms are confirmed as worn, replacing them with correctly matched components can remove excessive movement caused by those deteriorated parts. Verify all eight LEMFORDER references, OEM numbers and the VIN before ordering, followed by professional installation and wheel alignment.
Is wheel alignment required after replacing the LEMFORDER Front Upper & Lower Control Arms Set of 8 on Audi Q5 8R?
A professional wheel alignment check is strongly recommended after replacing Audi Q5 8R Front Upper & Lower Control Arms because these components are directly involved in guiding the front wheel assemblies and maintaining suspension geometry, and replacing several upper and lower suspension links at the same time represents significant work on the front multi-link suspension. This complete LEMFORDER set includes 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. When old control-arm bushes or joints are significantly worn, they may allow the wheel assemblies to move more than intended during braking, cornering or driving over uneven surfaces. Installing correctly matched new components can remove the unwanted movement caused by those worn parts, but new control arms alone do not confirm that the final wheel geometry is within specification. A professional alignment check allows the workshop to measure the wheel positions after the suspension work and make appropriate adjustments where the vehicle design permits. Correct alignment is important for predictable steering, straight-line stability and balanced tyre wear. Incorrect wheel geometry may 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. Alignment is particularly important after extensive multi-link suspension work because multiple position-specific arms have been removed and replaced. Before alignment, the technician should also inspect the remaining steering and suspension components. Steering tie rod ends should be checked carefully because they directly influence wheel direction and toe adjustment. Shock absorbers should be examined for leakage, physical damage and reduced damping performance. Wheel bearings should be checked when unusual noise, vibration or wheel movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when knocking or rattling occurs, although their primary function is different from wheel alignment. Tyres should have the correct pressure before measurements are taken, and existing abnormal tread wear should be noted because replacing suspension components cannot reverse tyre damage that has already occurred. Wheel balancing should be treated separately if vibration mainly appears at particular road speeds. After fitting the required LEMFORDER components in their correct positions, completing a professional wheel alignment check is an important final stage of the repair to help maintain suspension geometry, steering response and even tyre wear.
What problems can occur if worn Audi Q5 8R Front Upper & Lower Control Arms are not replaced?
Worn Audi Q5 8R Front Upper & Lower Control Arms can contribute to progressively increasing suspension noise, unwanted wheel movement, steering vibration, vague steering response, reduced directional stability and irregular tyre wear when deteriorated bushes, joints or mounting areas remain in service. Because the Audi Q5 8R uses a multi-link front suspension containing several position-specific arms, deterioration can develop in different components and may produce different symptoms depending on which suspension link is affected. This complete LEMFORDER kit contains 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01, while the supplied OEM references are 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. The product is listed for Audi Q5 8R 2008–2017. Suspension bushes are subjected to repeated compression, twisting and road-impact forces throughout normal vehicle operation. As they deteriorate, additional movement may develop between the wheel-side suspension and chassis. Early wear may produce an occasional knocking or clunking sound when the vehicle crosses potholes, speed breakers or damaged roads. As the deterioration becomes more significant, the suspension may feel less controlled and the steering response may become less precise. Excessive suspension movement can also contribute to changes in wheel positioning, which may lead to abnormal tyre wear when geometry is affected. Continuing to drive with significantly deteriorated suspension components can therefore increase tyre wear and may allow related symptoms to become progressively more noticeable. However, replacing all eight control arms without proper diagnosis is not recommended because several other components can produce similar symptoms. Steering tie rod ends can cause steering looseness or unwanted wheel movement. Shock absorbers can reduce suspension control if their damping performance deteriorates. Wheel bearings can cause noise, vibration or excessive movement. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links are another important area to inspect when knocking or rattling occurs over smaller road irregularities. Tyre pressure, tyre condition, wheel balancing and wheel alignment should also be considered during diagnosis. If professional inspection confirms significant wear across the corresponding upper and lower arms, replacing the diagnosed components can remove the excessive movement caused by those worn parts. Verify all eight LEMFORDER references and OEM numbers against the VIN and original suspension components before ordering.
Why is replacing all 8 Audi Q5 8R upper and lower control arms together beneficial when all eight arms are worn?
Replacing all eight Audi Q5 8R Front Upper & Lower Control Arms together can be beneficial when professional inspection confirms significant deterioration across the complete corresponding group because the Q5 8R multi-link front suspension relies on several separate links working together to guide the front wheel assemblies. This complete LEMFORDER package contains 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01, with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M. These components occupy different positions within the front suspension rather than being eight identical interchangeable arms, which is why correct part identification and installation position are important. Catalogue information, for example, identifies 38965 01 as right lower rear, 37487 01 as right lower front and 35685 01 as left upper front, with corresponding paired components for the opposite side. When all corresponding bushes, joints or mounting areas have accumulated substantial wear, replacing the complete diagnosed group during the same repair can bring these suspension components to a more consistent mechanical condition. This can be particularly useful when several arms are already significantly worn because replacing only one component may leave other deteriorated links requiring additional repair shortly afterwards. Completing the work together can also reduce repeated suspension dismantling and make it easier to perform a comprehensive alignment after the new components have been installed. Correctly matched new upper and lower control arms can remove excessive movement caused by worn bushes or joints and help the suspension maintain controlled wheel guidance. This may help address knocking, vague steering, reduced stability or abnormal tyre wear when the control arms are confirmed as the source of those symptoms. However, the existence of an eight-piece kit does not mean that every arm should automatically be replaced when only one component has failed. Each suspension link should be inspected individually, and replacement decisions should be based on actual condition. Other front axle components should also be inspected during the repair. Steering tie rod ends, shock absorbers and wheel bearings should be checked for wear, damage or excessive movement. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when suspension noise is present. Tyres should be examined for abnormal tread wear. When all eight corresponding arms are genuinely worn and the supplied references match the VIN, replacing the complete set followed by professional wheel alignment provides a comprehensive approach to the affected front suspension.
