Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Repair Steering Components

Check Power Steering Fluid:
- Locate the power steering fluid reservoir.
- Inspect the fluid level; if low, top off with the recommended fluid type (BMW CHF 11S).
- If fluid is dark or contaminated, consider flushing the system.
Examine Steering Rack and Tie Rods:
- Lift the vehicle using a jack and secure it with jack stands.
- Visually inspect the steering rack for leaks or physical damage.
- Check the tie rod ends for play by grasping them and attempting to move them laterally. Replace if worn.
Inspect Ball Joints:
- Check ball joints by lifting the wheel off the ground and shaking it up and down. If there is excess movement, the ball joint should be replaced.

3. Alignment Adjustment

After replacing any worn components, perform a four-wheel alignment.
Use a professional alignment machine to ensure all angles are set to manufacturer's specifications.

4. Test Drive

Reconnect the negative battery terminal.
Lower the vehicle and take it for a test drive.
Monitor for improved steering response and feel.
