LEMFÖRDER 39075 01 – Precision Steering Component

The LEMFÖRDER 39075 01 is a high‑performance steering component designed for modern front‑wheel drive vehicles. It serves as the critical link between the steering rack and the wheel assembly, translating driver input into precise wheel motion while withstanding the demanding forces of everyday driving.

Core Functionality

This part functions as a tie rod end, also referred to in various languages as “Spurstangenkopf”, “Rotule de direction”, or “Tête de barre d'accouplement”. Its primary role is to:

• Transmit steering torque from the rack to the wheel hub.
• Maintain accurate wheel alignment by providing a stable pivot point.
• Absorb shocks and vibrations through its integrated ball‑joint design, ensuring smooth handling.

Design & Construction

The component is engineered with the following key attributes:

• Material Composition: Constructed from high‑strength alloy steel that offers excellent fatigue resistance and corrosion protection. The surface is treated with a durable coating to extend service life.
• Ball Joint Integration: A precision ball joint allows for multi‑axis movement, enabling the wheel to pivot smoothly while maintaining alignment under load.
• Threaded Connection: Features an M14x1.5 thread size, compatible with standard steering rack housings and tie rod shafts used in many front‑wheel drive platforms.
• Compact Geometry: Designed to fit within tight engine bay spaces without compromising structural integrity.

Compatibility & Applications

The LEMFÖRDER 39075 01 is specifically engineered for use in the front axle of certain Audi models, including:

• Audi A5 (B9) Coupe
• Audi Q5 (B9)
• Audi A4 (B9) Avant

It is available for both the left and right sides of the vehicle, ensuring symmetrical handling characteristics. The part’s design aligns with the OEM specifications for these models, providing a seamless fit and performance parity.

Installation & Maintenance

Proper installation involves:

1. Aligning the tie rod end with the steering rack’s mounting point.
2. Tightening to manufacturer torque specifications, typically around 70–80 Nm, to secure a reliable connection without over‑tightening.
3. Checking for play after installation; any noticeable looseness indicates improper seating or damage.

Routine maintenance includes:

• Inspecting the ball joint for wear or debris accumulation.
• Re‑applying lubricant to the threaded interface if necessary.
• Replacing the component after a specified mileage threshold (often around 60,000–80,000 km) or when symptoms such as steering noise or uneven tire wear appear.

Performance Benefits

Choosing the LEMFÖRDER 39075 01 delivers several tangible advantages:

• Enhanced Steering Precision: The robust construction reduces flex, allowing for tighter steering response.
• Improved Durability: High‑grade materials and protective coatings resist corrosion and fatigue, extending the component’s lifespan.
• Consistent Handling: By maintaining proper wheel alignment, it contributes to predictable vehicle behavior during cornering and braking.
• Compatibility with OEM Standards: Its dimensions and thread specifications match original equipment, ensuring that performance is not compromised.

Key Specifications Summary

Conclusion

The LEMFÖRDER 39075 01 exemplifies engineering precision tailored for premium front‑wheel drive vehicles. Its combination of robust construction, exacting fitment, and reliable performance makes it an essential component for drivers who demand both safety and responsiveness from their steering system.
