Lemforder 1313701 Steering Rod Assembly

Overview of the Lemforder 1313701 Steering Rod Assembly

The Lemforder 1313701 Steering Rod Assembly is a high‑performance component designed to replace or upgrade the front steering linkage on select BMW and ALPINA models. This assembly integrates the tie rod end, ball joint, and steering shaft into a single, robust unit that delivers precise handling, reduced play, and enhanced durability.

Key Technical Features

• Material Composition: Constructed from hardened steel with a protective coating to resist corrosion and wear.
• Design Geometry: Engineered for optimal camber control, ensuring consistent tire contact during steering input.
• Load Capacity: Rated to withstand high lateral forces typical of sporty driving dynamics.
• Compatibility: Specifically matched to the front suspension architecture of BMW E39 (5 Series), E60/E61 (6 Series), and select ALPINA variants.
• Installation Method: Features a pre‑aligned mounting flange that simplifies assembly and guarantees correct alignment without additional shims.

Performance Benefits

When integrated into the steering system, the Lemforder 1313701 Steering Rod Assembly offers several measurable advantages:

1. Reduced Steering Effort: The precision‑machined ball joint reduces friction, allowing for lighter steering feel.
2. Improved Road Feedback: Enhanced stiffness translates to clearer feedback from the road surface, aiding driver confidence during cornering.
3. Extended Component Life: High‑grade steel and protective coatings mitigate wear on mating surfaces, extending overall suspension lifespan.
4. Consistent Alignment: The assembly’s geometry maintains proper toe and camber angles over time, reducing tire wear and maintaining handling characteristics.

Installation Overview

Installing the Lemforder 1313701 Steering Rod Assembly involves a straightforward replacement of the existing tie rod end and ball joint. The process typically follows these steps:

1. Secure the Vehicle: Raise the front axle with a jack and support it on jack stands.
2. Remove Old Components: Detach the steering shaft from the steering rack, then unscrew the old tie rod end from the ball joint.
3. Align the New Assembly: Position the new assembly’s mounting flange against the steering rack, ensuring proper alignment with the steering column.
4. Tighten Fasteners: Use a torque wrench to tighten all bolts to manufacturer specifications, typically around 30–35 Nm for the tie rod end and 20–25 Nm for the ball joint nut.
5. Verify Alignment: Perform a quick alignment check by turning the steering wheel through its full range and observing any binding or uneven movement.

Maintenance Tips

Although the Lemforder 1313701 Steering Rod Assembly is engineered for longevity, routine checks can further ensure optimal performance:

• Periodic Inspection: Every 20,000 km, inspect the tie rod end for signs of wear or looseness.
• Tightening Schedule: Re‑torque the ball joint nut and tie rod bolts at each service interval to maintain alignment.
• Lubrication: Apply a light silicone spray to the ball joint bearings during installation; avoid over‑lubricating, which can attract debris.
• Alignment Verification: After any suspension work or impact event, perform a professional wheel alignment to confirm that steering geometry remains within specifications.
