Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, wheel chocks.
Ensure the vehicle is parked on a level surface and securely lifted.

2. Inspect and Replace Worn Components

Inspect Tie Rods and Ball Joints
- Remove the front wheels using a socket set.
- Check for any movement in the tie rod ends and ball joints by attempting to wiggle them by hand.
Replace if Necessary
- If any component is found worn or loose, use a wrench to loosen the nuts and remove the tie rod end or ball joint.
- Install the new parts and torque to manufacturer specifications (usually around 35-45 ft-lbs for tie rods).

3. Check and Adjust Power Steering Fluid

Inspect Fluid Level
- Locate the power steering reservoir and check the fluid level.
Add Fluid
- If low, add the appropriate power steering fluid (typically CHF 11S for BMW).
Bleed System if Needed
- Turn the steering wheel fully from lock to lock to release any air bubbles.

4. Wheel Alignment

Perform Alignment
- Take the vehicle to a professional alignment shop to ensure proper angles are set.
Torque Specifications
- Ensure all bolts and nuts are torqued to the manufacturer specifications during reassembly.
