Solution

1. Preparation

Gather tools: socket set, torque wrench, alignment tool, OBD-II scanner, and tire pressure gauge.
Ensure the vehicle is on a level surface and securely raise it with jack stands if necessary.

2. Inspect and Tighten Steering Components

Sub-steps:
- Remove any covers or panels obstructing access to the steering components.
- Check the steering rack and tie rod ends for any play or looseness.
- Tighten bolts on the steering rack and tie rods to the manufacturer's specified torque values (refer to service manual).

3. Check and Adjust Wheel Alignment

Sub-steps:
- Use an alignment tool to measure the angles of the wheels.
- If misalignment is detected, adjust the alignment settings according to the manufacturer's specifications.
- Recheck to ensure the alignment is within the proper range.

4. Inspect Tires

Sub-steps:
- Measure tire pressure using a tire pressure gauge and inflate to the recommended PSI.
- Inspect tires for uneven wear; replace if necessary.
- Rotate tires if uneven wear is detected to promote even wear.
