Audi A4 B8 Front Upper & Lower Control Arms are important components of the front suspension system that help guide the front wheel assemblies, control suspension movement and maintain predictable steering, wheel positioning and road stability, 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 for the specified application when these references match the individual vehicle. The Audi A4 B8 uses a multi-link front suspension arrangement in which several suspension links work together rather than relying on one simple control arm on each side. Each arm has a particular position and function within this system, and together the upper and lower control arms help guide the wheel through its intended suspension travel while limiting unwanted movement. When the vehicle travels over normal roads, the suspension continuously moves as the tyres follow small changes in the road surface. Potholes, speed breakers, broken roads and uneven surfaces produce larger suspension movement and stronger forces through the control arms, bushes, joints and mounting points. During braking, vehicle weight transfers towards the front axle and increases the load acting through the suspension. Cornering creates lateral forces through the tyres and wheel assemblies, while acceleration and changes in road level continuously alter suspension loading. The upper and lower control arms therefore work together with ball joints, suspension bushes, steering tie rod ends, shock absorbers, springs, wheel bearings and other chassis components. When bushes, joints or mounting areas become worn, the suspension can develop unwanted movement. Depending on which arm is affected, common symptoms may include knocking or clunking over uneven roads, steering vibration, vague steering response, reduced straight-line stability, abnormal tyre wear or a less controlled feeling from the front axle. These symptoms should be professionally diagnosed because other components can produce similar problems. Steering tie rod ends, ball joints, 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 knocking or rattling occurs over rough surfaces. Before ordering this complete set, verify all supplied LEMFORDER numbers and OEM references against the Audi VIN and original suspension components. Professional installation followed by a complete wheel alignment check is recommended after replacement.

LEMFORDER 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 are supplied in this Audi A4 B8 Front Upper & Lower Control Arms set of 8 together with OEM references 4G0407693J / 4G0407694J / 8K0407151F / 8K0407152F / 8K0407505M / 8K0407506M / 8K0407509M / 8K0407510M, but exact compatibility should always be verified against the individual vehicle VIN, original suspension components and required OE references before ordering. The Audi A4 B8 model designation alone should not be treated as sufficient confirmation for every vehicle because suspension specifications can differ according to production configuration, drivetrain, engine, suspension package and other vehicle equipment. This is especially important with a multi-link suspension system because several arms can have a similar overall appearance while differing in dimensions, mounting geometry, bush arrangement, joint configuration or intended installation position. Customers should therefore compare each supplied LEMFORDER reference and corresponding OEM number with the parts required for their particular Audi A4 B8 rather than relying only on a visual comparison. Correct part identification is particularly important when purchasing a complete set of 8 because every component must correspond to its intended location within the front suspension. Correctly matched upper and lower suspension arms work together to guide wheel movement and maintain controlled suspension geometry during normal driving, braking and cornering. If one or more existing control-arm bushes or joints have developed excessive wear, the driver may experience knocking, steering vibration, loose handling, instability or uneven tyre wear. However, these symptoms can also originate from other front suspension or steering components. Steering tie rod ends and ball joints should be checked for excessive movement. Shock absorbers should be inspected for leakage or reduced damping performance. Wheel bearings should be examined when noise or vibration is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links can also produce knocking or rattling over rough roads. Tyre pressure, tyre condition, wheel balancing and alignment should also be considered during diagnosis. If professional inspection confirms that multiple upper and lower arms require replacement and these supplied references match the vehicle, the complete LEMFORDER set of 8 provides a convenient solution for the diagnosed repair. Verify all eight LEMFORDER numbers, all supplied OEM references and the VIN before purchase, and use professional installation followed by wheel alignment after replacement.

This Audi A4 B8 Front Upper & Lower Control Arms package contains a set of 8 because the front suspension uses multiple individual suspension links to guide and control the wheel assemblies, and this LEMFORDER package combines 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 into one complete front suspension arm set when these references correspond with the vehicle. Unlike a simpler suspension layout that may use one main lower arm on each side, the Audi A4 B8 multi-link arrangement uses several links positioned around the front wheel assembly. These different arms work together to control wheel movement as the suspension compresses and extends. Each component has a specific position, so the eight arms should not be treated as interchangeable simply because they belong to the same kit. The advantage of a complete set is most apparent when professional inspection shows that several or all of the corresponding control-arm bushes, joints or mounting areas have deteriorated. Because these components operate through the same vehicle mileage and are exposed to similar road conditions, it is possible for several suspension links to show wear during the same period, although the exact rate of deterioration can differ from one component to another. One side may experience greater pothole or road-edge impacts, and one particular bush may deteriorate faster than another. Therefore, buying a set of 8 does not mean every arm must automatically be replaced without inspection. When the complete group is confirmed as worn, replacing the affected upper and lower arms during one repair can bring those suspension components to a more consistent condition and reduce the need to repeatedly dismantle the front suspension for individual worn arms. The rest of the front axle should still be inspected carefully. Steering tie rod ends, ball joints, shock absorbers and wheel bearings can also develop wear. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be inspected when knocking or rattling is present. Tyres should be checked for irregular wear because deteriorated suspension components or incorrect alignment can affect tread condition. Before ordering the complete set, verify all LEMFORDER numbers and OEM references against the Audi VIN and original parts. After installation, a professional wheel alignment check is strongly recommended.

Common symptoms of worn Audi A4 B8 Front Upper & Lower Control Arms can include knocking or clunking from the front suspension, rattling over rough roads, steering vibration, vague steering response, reduced straight-line stability, unusual movement during braking, uneven tyre wear or a generally less controlled feeling from the front axle, although these symptoms can have several possible causes and should be professionally diagnosed before replacing this LEMFORDER set containing 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 A4 B8 front multi-link suspension contains several arms and bushes, so deterioration can occur in different locations and produce different symptoms. Rubber bushes are repeatedly compressed and twisted as the suspension moves. Over time, they may harden, crack, deform or separate. Joints and mounting areas can also develop excessive play. A knocking sound may become noticeable when travelling over potholes, broken roads or speed breakers because a worn component allows more movement than intended. Steering may feel vague or less precise if suspension play affects wheel control. Vibration may sometimes be transmitted through the steering wheel, especially when other suspension, steering or wheel-related issues are also present. Uneven tyre wear can develop when suspension wear contributes to changes in wheel geometry. Some drivers may notice the vehicle feels less settled under braking because braking forces create significant loading through the front suspension. However, none of these symptoms should be used alone to diagnose a failed control arm. Steering tie rod ends can cause loose steering or wheel movement. Ball joints can produce play or knocking. Shock absorbers can reduce suspension control when their damping performance deteriorates. Wheel bearings can produce noise or vibration. Wheel and tyre problems can also cause steering vibration. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links are another common area to inspect when rattling or knocking occurs over smaller road irregularities. A workshop should therefore inspect the complete front suspension before deciding whether individual arms or the complete set require replacement. If multiple upper and lower arms are confirmed as worn, verify all eight LEMFORDER references and supplied OEM numbers against the VIN before ordering. Professional installation and wheel alignment are recommended after replacement.

Replacing Audi A4 B8 Front Upper & Lower Control Arms as a complete LEMFORDER set of 8 can be beneficial when professional inspection confirms significant deterioration across the corresponding suspension arms because the package combines LEMFORDER 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 into one comprehensive front suspension arm package when these references match the individual vehicle. The Audi A4 B8 multi-link suspension relies on several control arms working together, which means deterioration may be present in more than one bush, joint or suspension link at the same time, particularly after substantial road use. When several corresponding components are already significantly worn, replacing the diagnosed group during the same repair can bring those parts to a more consistent mechanical condition. It may also reduce the likelihood of completing one suspension repair and then having to dismantle related areas again shortly afterwards because another already-worn arm requires replacement. New correctly matched arms can remove unwanted movement associated with deteriorated bushes, joints or mounting points and help the front suspension maintain more controlled wheel positioning. This may help address knocking, vague steering, instability or abnormal tyre wear when those symptoms have been correctly traced to worn control arms. A complete kit can also simplify parts sourcing because the required upper and lower suspension arms are grouped into one package rather than being purchased individually. However, the existence of an eight-piece kit does not mean replacing every component is automatically necessary whenever a single arm develops a fault. Professional inspection should determine the actual condition of every suspension component. Steering tie rod ends, shock absorbers and wheel bearings should also be checked because they can affect steering and suspension behaviour. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should be inspected for play when suspension noise is present. Tyres should be checked for uneven wear and wheel condition should also be assessed. Before ordering, verify all eight LEMFORDER part numbers and OEM references against the vehicle VIN and original components. When the complete corresponding group is confirmed as worn, replacement as a complete set followed by professional wheel alignment can provide a comprehensive approach to restoring the affected front suspension components.

This LEMFORDER set of 8 can be considered for Audi A4 B8 front suspension replacement when the supplied part numbers 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 match the individual vehicle, because LEMFORDER is an established steering and suspension component brand and this package provides multiple corresponding upper and lower control arms together for a comprehensive front suspension repair. Correct part identification is especially important on the Audi A4 B8 because its multi-link front suspension contains several separate arms that can appear similar but perform different functions and occupy different positions. Customers should therefore verify every supplied LEMFORDER number and OEM reference against the VIN and original components instead of selecting the complete kit only because the vehicle is described as an Audi A4 B8. When professional inspection confirms significant deterioration across multiple upper and lower suspension arms, replacing the diagnosed components can remove unwanted movement caused by worn bushes, joints or mounting areas. Correctly functioning control arms help guide the wheel assemblies during suspension travel and support predictable steering and wheel positioning. A complete set can also make parts purchasing more convenient when several corresponding arms need replacement at the same time. However, suspension performance depends on the condition of the entire front axle, not only the eight control arms included in this package. Steering tie rod ends should be checked for excessive play. Ball joints and other suspension bushes should be examined where applicable. Shock absorbers should be inspected for leakage, damage and damping condition, 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 knocking or rattling occurs over uneven roads. Tyres should be checked for correct pressure, physical damage and abnormal wear. Wheel balancing should be considered if vibration is speed-related. For customers specifically looking for a comprehensive LEMFORDER Audi A4 B8 suspension kit, this eight-piece package provides the listed upper and lower control-arm references together when they match the vehicle. Verify VIN and OEM compatibility before purchase, use professional installation for every arm in its correct position, and complete a wheel alignment check after replacement to help maintain correct suspension geometry, predictable steering, stable handling and even tyre wear.

Audi A4 B8 Front Upper & Lower Control Arms are important parts of the front multi-link suspension because they help guide the front wheel assemblies, control wheel movement and maintain predictable steering, suspension geometry and road stability, and this complete LEMFÖRDER set of 8 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. Unlike a simpler suspension arrangement using only one major control arm on each side, the Audi A4 B8 front suspension uses several individual links positioned around each front wheel assembly. Each arm performs a specific role within this system and should be fitted in its intended position. The upper and lower arms work together to guide the wheels as the suspension compresses and extends over different road surfaces. Even when driving on a smooth road, these components continuously move as the tyres respond to small surface changes. Potholes, broken roads and speed breakers create larger movements and stronger forces through the suspension bushes, joints and mounting areas. Braking transfers vehicle weight towards the front axle, while cornering produces lateral forces through the tyres and wheel assemblies. Because several links share these loads, excessive wear in one or more components can affect the overall behaviour of the front suspension. Worn bushes or joints may contribute to knocking, clunking, vague steering, steering vibration, reduced directional stability or abnormal tyre wear. If several arms have developed significant play, the vehicle may feel less controlled over uneven roads or during braking and cornering. However, these symptoms do not automatically mean that all eight arms require replacement. A workshop should inspect each component individually and check the rest of the front suspension. Steering tie rod ends, ball joints, shock absorbers and wheel bearings can produce similar symptoms. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected if rattling or knocking is present. Tyres should be checked for correct pressure, physical damage and irregular tread wear. When inspection confirms significant deterioration across the corresponding upper and lower arms, replacing the diagnosed components with correctly matched parts can remove excessive movement caused by those worn components. Verify all LEMFÖRDER and OEM references against the VIN before purchase, followed by professional installation and wheel alignment after replacement.

A professional wheel alignment check is strongly recommended after replacing an Audi A4 B8 Front Upper & Lower Control Arms set because these suspension links directly participate in controlling the position and movement of the front wheel assemblies, and replacing multiple arms can affect or reveal changes in suspension geometry that should be measured after installation. This LEMFÖRDER package contains eight suspension components: 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. When old suspension bushes or joints are significantly worn, they may allow the wheels to move beyond their intended positions under braking, cornering or road impact. Installing new correctly matched control arms removes the excessive movement caused by those diagnosed worn components, but installing new parts alone does not prove that wheel alignment is correct. Alignment equipment allows a workshop to measure the front and rear wheel geometry and determine whether adjustment is required. Correct geometry helps maintain predictable steering response, straight-line stability and balanced tyre wear. Incorrect geometry may contribute to steering pull, an off-centre steering wheel, reduced directional stability or accelerated wear on the inner or outer edges of the tyres. Alignment becomes particularly important after extensive front suspension work because several components have been removed and installed. Before the alignment is completed, the workshop should inspect other steering and suspension parts because excessive play elsewhere can interfere with accurate measurement. Steering tie rod ends should be checked carefully because they influence wheel direction and toe adjustment. Ball joints and remaining suspension bushes should be inspected for play. Shock absorbers should be checked for leakage, physical damage and damping condition, while wheel bearings should be examined if noise or excessive movement is present. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links should also be inspected when suspension noise occurs, although these components perform a different function from wheel alignment. Tyres should have the correct pressure before alignment and existing tread wear should be examined. Wheel balancing should be considered separately if vibration mainly occurs at particular speeds. After correctly installing the required LEMFÖRDER arms, a professional alignment check provides an important final step in the suspension repair.

Worn Audi A4 B8 Front Upper & Lower Control Arms can contribute to progressively increasing suspension noise, excessive wheel movement, steering vibration, vague steering response, reduced road stability and irregular tyre wear if deteriorated bushes, joints or mounting areas remain in service, although the exact symptoms depend on which components are worn and how severe the deterioration has become. The Audi A4 B8 front suspension uses several separate links, which means deterioration can develop in different areas rather than appearing in one single suspension arm. This LEMFÖRDER set groups 38965 01, 38964 01, 37486 01, 37487 01, 35685 01, 35686 01, 35687 01 and 35688 01 together for a comprehensive repair when the supplied OEM references match the vehicle. Available parts catalogues identify these references across different upper and lower positions, illustrating why correct position-specific installation matters. Suspension bushes are repeatedly compressed and twisted whenever the wheels move over changing road surfaces. Over time, rubber can harden, crack, deform or separate, while joints and mounting areas may develop excessive movement. Early deterioration may produce occasional knocking over potholes or speed breakers. As wear increases, the driver may notice more frequent clunking, vague steering or reduced confidence in straight-line stability. Suspension play can also contribute to changes in wheel geometry, potentially causing accelerated inner or outer tyre wear. Ignoring significant wear can therefore increase the number of components requiring attention later and may shorten tyre life. However, a complete diagnosis remains essential because the control arms are only one part of the front suspension. Steering tie rod ends can cause steering looseness or unwanted wheel movement. Ball joints can produce knocking and play. Worn shock absorbers can reduce suspension control, while wheel bearings can cause noise or vibration. Sway bar links, Sway links, Anti roll link rods and Stabiliser sway links can produce rattling or knocking over smaller road irregularities. Tyre pressure, tyre condition, wheel balancing and wheel alignment should also be checked where appropriate. If inspection confirms significant deterioration across several control arms, delaying replacement may allow the symptoms associated with those worn components to become progressively more noticeable. Verify all supplied LEMFÖRDER and OEM references against the vehicle VIN before ordering and use professional installation followed by wheel alignment.

Replacing all eight Audi A4 B8 Front Upper & Lower Control Arms together can be beneficial when professional inspection confirms significant deterioration across the complete corresponding group because the front multi-link suspension relies on several separate links working together to guide the wheel assemblies, and this LEMFÖRDER package provides 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. When several bushes and joints have already accumulated similar mileage and show significant deterioration, replacing the complete diagnosed group during one repair can bring those suspension components to a more consistent mechanical condition. This can be preferable to repeatedly dismantling related areas of the suspension as individual already-worn components progressively require replacement. Correctly matched new upper and lower arms can remove unwanted movement caused by deteriorated bushes, joints or mounting areas and help restore controlled wheel guidance. When the existing arms are responsible for knocking, vague steering, instability or abnormal tyre wear, replacing the worn components can address the mechanical source of those symptoms. A complete kit also simplifies parts sourcing because the corresponding suspension links are grouped together instead of being ordered individually. However, it is important not to interpret an eight-piece kit as a requirement to replace eight serviceable components whenever only one arm has failed. A technician should inspect each arm and determine whether the complete set or only selected components require replacement. Other parts should also be checked during the repair because installing eight new control arms cannot correct unrelated faults. Steering tie rod ends should be inspected for play. Shock absorbers should be checked for leakage and damping condition. 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 checked for worn joints. Tyres should be inspected for abnormal tread wear that may have developed before the suspension repair. When all corresponding control arms are genuinely worn, replacing them together can provide a comprehensive front suspension refresh, followed by professional wheel alignment to verify geometry.
