- Check for uneven wear patterns indicating improper alignment or balance.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using a socket set.
- Take the wheel to a tire shop or use a wheel balancer.
- Add weights as needed to achieve balance; ensure the wheel is reattached securely.

4. Wheel Alignment

Sub-steps:
- If uneven tire wear is detected, check the alignment using alignment tools.
- Adjust the camber, caster, and toe settings according to the manufacturer’s specifications.
- Test drive the vehicle to confirm alignment is correct.

5. Suspension and Driveline Inspection
