Solution

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 ensure safety during repairs.

2. Inspect and Tighten Steering Column Bolts

Sub-steps:
- Remove the lower steering column cover using a Torx screwdriver.
- Inspect all bolts and fasteners related to the steering column for tightness.
- If any bolts are loose, tighten them to the manufacturer's specifications (typically 15-20 Nm).

3. Replace Worn Tie Rod Ends

Sub-steps:
- Lift the front of the vehicle and secure it with jack stands.
- Remove the wheel to access the tie rod ends.
- Use a wrench to disconnect the tie rod end from the steering knuckle.
- Replace with a new tie rod end and torque to specification (typically 40-50 Nm).

4. Inspect and Replace Steering Shaft U-Joints

Sub-steps:
- Remove any covers obstructing access to the steering shaft.
- Check for play in the u-joints; if excessive, remove the steering shaft.
- Replace the u-joints if necessary and reassemble, ensuring proper alignment.

5. Check and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir and remove the cap.
- Check fluid level; if low, top off with the recommended fluid type (often CHF 11S).
- If the fluid is dirty or aerated, perform a fluid exchange.
