Key Features

• High-Strength Construction: Made from hardened steel with a protective coating to resist corrosion and wear.
• Integrated Tie‑Rod End: The assembly includes a pre-attached tie‑rod end, reducing the number of separate parts required during installation.
• Precision Alignment: Designed to match OEM specifications for steering geometry, ensuring optimal vehicle dynamics.
• Durable Bushings: Equipped with high-quality polyurethane bushings that provide smooth operation and long service life.
• Compatibility: Suitable for a variety of models including BMW 3 Series Coupé (E46), M3 variants, and other vehicles that use the 27115 02 reference part number.

Technical Specifications

Installation Guide

The steering rod assembly is engineered for straightforward installation, allowing mechanics to replace the entire unit in a single operation. Follow these steps:

1. Secure the Vehicle: Raise and support the vehicle on jack stands; ensure it is stable before proceeding.
2. Remove Old Assembly: Detach the existing steering rod by loosening the tie‑rod end bolts and removing any retaining clips. Carefully disconnect the steering linkage from the wheel hub assembly.
3. Position New Assembly: Align the new Lemforder 2711502 with the steering column and wheel hub. Ensure that the tie‑rod end is correctly seated in the steering knuckle.
4. Tighten Fasteners: Secure all bolts to the manufacturer’s torque specifications, typically around 80–100 Nm for the tie‑rod end screws.
5. Check Alignment: Verify that the steering wheel remains centered when the wheels are straight. Adjust if necessary before final tightening.
6. Test Drive: Conduct a short test drive to confirm smooth steering response and absence of unusual noises.

Performance Benefits

• Enhanced Handling: The precise geometry ensures that the vehicle responds accurately to driver inputs, improving cornering stability.
• Reduced Wear: High-quality bushings and corrosion-resistant materials extend the lifespan of the steering system.
• Lower Maintenance: Integrated tie‑rod end eliminates the need for separate components, simplifying future replacements.
• Consistent Ride Quality: The assembly’s design maintains consistent steering feel across a range of speeds and road conditions.

Material Composition

The core of the steering rod is fabricated from high-grade alloy steel, chosen for its excellent tensile strength and fatigue resistance. The outer coating consists of an anti-corrosion paint system that protects against rust in harsh environments. The polyurethane bushings provide a balance between stiffness and damping, reducing vibration while maintaining precise alignment.

Maintenance Tips

• Inspect the steering rod for signs of wear or damage every 20,000 km.
• Check the integrity of the polyurethane bushings; replace if they appear cracked or worn.
• Avoid excessive force on the steering wheel during operation to prevent premature component failure.

FAQs

Can I use this assembly in a vehicle other than BMW?

If the vehicle’s steering geometry and tie‑rod dimensions match those specified for the 2711502, it can be used. Always verify compatibility before installation.

What is the expected lifespan of the steering rod assembly?

With proper maintenance, the assembly typically lasts between 80,000–120,000 km, depending on driving conditions and usage patterns.

Is a special tool required for installation?

A standard set of wrenches and torque tools is sufficient. No proprietary or specialized equipment is necessary.

Conclusion

The Lemforder 2711502 Steering Rod Assembly offers a reliable, high-performance solution for steering systems in BMW vehicles and compatible models. Its robust construction, integrated design, and precise engineering make it an excellent choice for both professional mechanics and dedicated automotive enthusiasts seeking to maintain or restore optimal vehicle handling.
