Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles if needed.

2. Tire Inspection and Rotation

Inspect Tires:
- Assess all tires for damage; replace if necessary.
- Measure tread depth using a tread depth gauge.
Rotate Tires:
- Use a jack and jack stands to lift the vehicle.
- Rotate tires according to the recommended pattern (front to back, side to side) if uneven wear is found.

3. Wheel Balancing

Remove Wheels:
- Use a lug nut wrench to loosen and remove the lug nuts.
- Take the wheels to a tire shop for balancing.
Balance Wheels:
- Have a technician balance the wheels using a dynamic balancing machine.
- Reinstall wheels on the vehicle and torque lug nuts to the manufacturer’s specifications (typically 76 ft-lbs).

4. Suspension Inspection

Inspect Components:
- Visually check shocks, struts, and control arms for any signs of wear or damage.
- Replace any worn or damaged components as necessary.

5. Wheel Alignment

Perform Alignment:
- Use an alignment rack to check the alignment settings.
- Adjust camber, caster, and toe to match manufacturer specifications.
