1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add fluid if low (use BMW-approved fluid).

Visually check the power steering pump for leaks.
If leaks are present, replace the power steering pump:
1. Remove the serpentine belt using a wrench.
2. Unbolt the power steering pump from its mounting bracket.
3. Disconnect the fluid lines (be cautious of fluid spill).
4. Install the new pump by reversing the removal steps.

4. Examine Steering Rack

Inspect the steering rack for play or leaks.
If needed, replace the steering rack:
1. Disconnect tie rod ends from the steering knuckles.
2. Unbolt the steering rack from the subframe.
3. Remove any additional mounting hardware and disconnect fluid lines.
4. Install the new steering rack by reversing the removal steps.

5. Tire Pressure and Condition

Check all tire pressures using a tire gauge; inflate to the recommended PSI.
Inspect tires for uneven wear or damage; replace if necessary.
