Installation Guide
The following steps outline a typical installation procedure for the left‑hand steering rod assembly on a BMW E46. Always consult your vehicle’s service manual before beginning work.
- Preparation: Raise the front of the vehicle using jack stands and secure it. Remove the wheel to access the steering rack.
- Disconnect Power Steering Pump: Detach the hydraulic line from the rack to prevent fluid spillage during removal.
- Remove Old Rod: Unscrew the bolts that attach the existing steering rod to the rack and wheel hub. Carefully slide the rod out of its housing.
- Install New Assembly: Position the new Lemfrder 2166602 in place, aligning the bolt holes with those on the rack and hub. Tighten bolts to manufacturer’s torque specifications (typically 30–35 Nm).
- Reconnect Power Steering: Reattach the hydraulic line and check for leaks.
- Reinstall Wheel & Lower Vehicle: Put the wheel back on, lower the car, and perform a test drive to confirm proper steering response.

- Aftermarket Modifications: Installing on compatible Brilliance, Alpina, and Z4 chassis for improved handling.
Maintenance Tips
While the assembly is designed to be low‑maintenance, periodic checks can prolong its life:
- Inspect for Wear: Every 20,000 miles, examine the rod for signs of bending or corrosion.
- Check Bolt Tightness: Ensure all mounting bolts remain at specified torque values after any suspension work.
- Lubricate Bearings: If the assembly includes grease fittings, apply a light coat of high‑temperature grease annually.
