Product Overview

The Lemförder 39077 01 Tie Rod End is a high‑performance steering component engineered for the front axle of Audi models such as the A8 D4, A8L D4, and S8 D4. Designed to replace the original equipment (OE) part, it delivers precise steering geometry, durability, and reliable handling under demanding driving conditions.

Key Features

• Exact OE Match: Identical dimensions and mounting specifications to the factory part, ensuring seamless integration without modification.
• Robust Construction: Made from hardened steel with a corrosion‑resistant coating that resists wear, rust, and high temperatures.
• Precision Ball Joint: Equipped with a multi‑layered ball bearing system that reduces friction and extends service life.
• High Load Capacity: Designed to withstand the steering forces of large luxury vehicles, providing stability at both low and high speeds.
• Easy Installation: Comes with all necessary hardware (bolts, washers) and clear mounting instructions for a quick swap.

Compatibility

The tie rod end is specifically calibrated for the following Audi platforms:

• Audi A8 D4 (model codes 4H2, 4H8, 4HC, 4HL) – 2009‑2018
• Audi A8L D4 – 2009‑2018
• S8 D4 – 2009‑2018
• Other front‑axle vehicles that share the same steering geometry and mounting points.

Installation Guide

1. Preparation: Secure the vehicle on a flat surface, lift the front wheel with a jack, and support it with jack stands. Remove the wheel to access the tie rod assembly.
2. Remove Old Tie Rod End: Loosen the mounting bolts using an impact wrench or socket set. Carefully detach the old end from the steering knuckle and pull the ball joint out of the steering shaft.
3. Install New Component: Align the new tie rod end with the steering shaft, ensuring the ball joint sits flush against the shaft’s bearing. Tighten the mounting bolts to the manufacturer’s torque specification (typically 80–90 Nm).
4. Reassemble: Reinstall the wheel and lower the vehicle. Perform a quick spin test to confirm smooth rotation and no binding.
5. Alignment Check: For optimal handling, have a professional alignment performed after installation.
