Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Tire Inspection and Balancing

Sub-steps:
- Remove the wheel covers or caps if applicable.
- Loosen lug nuts using a socket wrench.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels and inspect the tires for uneven wear or visible damage.
- If tires are damaged, replace them with new ones.
- Have the tires balanced on a wheel balancer.
- Reinstall the wheels, tightening lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
- After balancing, check the alignment using an alignment machine.
- Adjust the alignment settings as needed to match manufacturer specifications.
- Confirm that the steering wheel is centered after alignment.

4. Suspension and Bearing Inspection

Sub-steps:
- Inspect all suspension components (struts, control arms, bushings) for signs of wear or damage.
- Replace any worn components as necessary.
- Check wheel bearings by spinning the wheel and feeling for roughness or noise.
- If wheel bearing is faulty, replace it using a bearing puller and press.
