LEMFÖRDER 35686 01 Track Control Arm For Audi A4 / S4

LEMFOERDER 35686 01 Track Control Arm is a high‑performance suspension component engineered specifically for the Audi A4 / S4 series, covering model years 2007 through 2015. This part replaces the original upper control arm (also known as the wishbone or track arm) on the front right side of the vehicle, ensuring optimal handling, durability, and compatibility with OEM specifications.

Key Features & Technical Highlights

Material Integrity: Crafted from high‑strength alloy steel, the arm offers superior fatigue resistance while maintaining a lightweight profile. The surface is treated with an anti‑corrosion coating that protects against rust and environmental degradation, extending service life under harsh driving conditions.

Precision Geometry: Designed to match the exact wishbone geometry of the Audi A4/S4 platform, the arm preserves steering geometry, camber control, and wheel alignment. This precision ensures that the vehicle’s handling characteristics remain consistent with factory specifications after installation.

Robust Mounting: The component features integrated mounting points compatible with the existing upper ball joint and lower arm attachments. All fasteners are engineered to withstand high torsional loads, providing a secure connection that resists loosening over time.

Compatibility & Fitment: This part is specifically designed for the 8K2 (A4) and B8 (S4) chassis codes. It fits the front right upper track arm position without requiring modifications to surrounding suspension components. The design also accommodates common aftermarket upgrades such as performance bushings or upgraded steering racks.

Ease of Installation: The arm’s standardized dimensions and pre‑drilled holes allow for straightforward installation using conventional tools. No special machining is required, making it suitable for both professional shops and experienced DIY mechanics.

Performance Benefits

Enhanced Handling: By restoring the original geometry of the upper control arm, the part helps maintain accurate wheel camber and caster angles, which are critical for cornering stability and tire wear distribution.

Improved Durability: The alloy construction resists fatigue cracking that can occur in older or heavily used stock arms. This results in a longer lifespan, especially under aggressive driving or high‑speed conditions.

Consistent Ride Quality: With the correct track arm geometry, the suspension system delivers a balanced ride feel, reducing body roll and maintaining tire contact patch during dynamic maneuvers.

Installation Overview

1. Preparation: Secure the vehicle on jack stands. Remove the wheel and disconnect the upper ball joint from the steering knuckle.
2. Removal of Stock Arm: Loosen the mounting bolts that attach the stock upper control arm to the chassis. Carefully detach the arm, noting any alignment marks or torque specifications.
3. Installation of LEMFOERDER 35686 01: Position the new arm onto the chassis and align the mounting holes with the existing bolt locations. Tighten bolts in a cross‑pattern to ensure even load distribution.
4. Reattach Ball Joint: Secure the upper ball joint to the steering knuckle, applying the manufacturer’s torque specifications.
5. Alignment Check: After installation, perform a wheel alignment to confirm that camber, caster, and toe settings are within factory tolerances.

Maintenance Tips

• Inspect Fasteners: Periodically check the mounting bolts for tightness. Re‑torque if necessary after driving cycles or when experiencing unusual handling symptoms.
• Check for Wear: Inspect the ball joint and bushings for signs of wear or damage. Replace any compromised components to maintain safety and performance.
• Clean Regularly: Keep the arm free from road salt, dirt, and debris to prevent corrosion buildup on the mounting surfaces.
