Solution

1. Preparation

Gather tools: jack, jack stands, wheel chocks, torque wrench, alignment tool.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electronic suspension components.

2. Tire Rotation

Sub-steps:
- Remove the wheel lug nuts using a socket set.
- Rotate tires according to the manufacturer's recommended pattern (front to back or side to side).
- Reinstall lug nuts and torque them to specifications (typically 80-100 ft-lbs for BMW).

3. Wheel Alignment

Sub-steps:
- Elevate the vehicle and remove the front wheels if necessary for clear access.
- Attach the alignment tool to the front wheels and adjust according to the manufacturer's specifications.
- Adjust camber, caster, and toe settings as needed.
- Recheck alignment after adjustments.

4. Suspension Inspection and Repair

Sub-steps:
- Inspect struts and shocks for leaks and proper damping response.
- Check control arms and bushings for wear; replace any damaged components.
- Tighten any loose bolts and replace worn bushings as necessary.

5. Reinstallation and Final Checks

Sub-steps:
- Reinstall the front wheels and torque lug nuts.
- Lower the vehicle and perform a test drive to evaluate any changes in handling.
