Lemförder 37847 01 – Tie Rod End

The LEMFOERDER 37847 01 is a high‑performance Tie Rod End, engineered to deliver precise steering geometry and reliable durability for modern front‑wheel drive vehicles. Designed with the rigorous demands of Audi TT, TT Roadster, and similar models in mind, this component ensures optimal handling characteristics while resisting wear under extreme driving conditions.

Key Features & Technical Highlights

• Material Composition: Constructed from a hardened steel alloy that offers superior tensile strength and corrosion resistance. The material is selected to withstand the high loads experienced at the steering pivot point.
• Precision Machining: Each unit undergoes CNC machining to achieve tight tolerances, guaranteeing smooth operation and minimal play in the steering system.
• Ball‑Joint Design: The internal ball joint provides a low‑friction pivot point, allowing for responsive steering while maintaining structural integrity during cornering forces.
• Compatibility: Specifically engineered to fit the front axle of Audi TT (FV3, FVP, FV9), TT Roadster, and other vehicles that use the 8S0423812A reference. The design accommodates both left and right side installations.
• Load Capacity: Rated for high load conditions typical in performance driving, ensuring longevity even under aggressive steering inputs.
• Surface Finish: A protective coating reduces wear and extends service life by mitigating galling and corrosion at the joint interface.

Installation & Maintenance Overview

Installing the LEMFOERDER 37847 01 requires a few critical steps to ensure optimal performance:

1. Removal of Old Component: Carefully detach the existing tie rod end, noting any alignment marks or torque specifications.
2. Inspection of Steering Rack: Verify that the steering rack and associated bushings are free from damage. Replace any worn parts before installing the new unit.
3. Alignment Check: Use a proper alignment tool to confirm that the steering axis remains within manufacturer tolerances during installation.
4. Tightening Sequence: Follow the specified torque sequence (typically 30–35 Nm for the outer nut, then 20–25 Nm for the inner nut) to avoid over‑tightening or under‑tightening.
5. Lubrication: Apply a high‑quality steering grease to the ball joint bearings before final tightening to reduce friction and prevent premature wear.

Regular maintenance involves inspecting for play, checking grease condition, and ensuring that all fasteners remain secure. A routine check every 10,000–15,000 miles is recommended for drivers who frequently engage in spirited driving or tow heavy loads.

Performance Benefits

• Enhanced Handling: The precise geometry and low‑friction ball joint contribute to tighter steering response and improved cornering stability.
• Durability Under Stress: High‑grade steel construction resists fatigue, making the component suitable for both daily commuting and high‑performance driving scenarios.
• Reduced Steering Effort: The optimized design lowers steering effort at low speeds while maintaining control at higher velocities.
• Consistent Alignment: Maintains wheel alignment over time, reducing uneven tire wear and preserving suspension geometry.

Applications & Vehicle Compatibility

The LEMFOERDER 37847 01 Tie Rod End is tailored for a range of Audi models that share the same front‑axle architecture:

• Audi TT (FV3, FVP, FV9) – both left and right side installations.
• Audi TT Roadster – compatible with the 8S0423812A reference.
• Other vehicles using the same steering rack geometry, such as certain compact performance cars that adopt the Audi TT platform.

Its universal fitment across left/right sides simplifies inventory management for repair shops and enthusiasts alike.

Quality Assurance & Manufacturing Standards

The component is produced under strict quality control protocols, including:

• ISO 9001 certification adherence during manufacturing.
• In‑process dimensional inspections using laser measurement systems.
• Final functional testing on a steering rack test rig to verify load handling and rotational smoothness.

This rigorous process ensures that every unit meets or exceeds OEM specifications, providing confidence in both performance and safety.

Why Choose the LEMFOERDER 37847 01?

• OEM‑Grade Reliability: Designed to match original equipment standards, guaranteeing seamless integration with existing vehicle systems.
• Long‑Term Value: The combination of high‑quality materials and precise engineering delivers a component that outlasts many aftermarket alternatives.
• Performance Focused: Ideal for drivers who demand responsive steering, whether on everyday roads or spirited track sessions.
• Ease of Installation: The design aligns with standard automotive service procedures, reducing labor time and potential errors.

Conclusion

The LEMFOERDER 37847 01 Tie Rod End stands out as a premium choice for anyone seeking to maintain or enhance the steering performance of Audi TT, TT Roadster, and related models. Its robust construction, precise engineering, and proven compatibility make it an indispensable component for both routine maintenance and high‑performance applications.
