Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
If necessary, lift the vehicle using a jack and secure it with jack stands.

2. Tire Inspection and Replacement

Inspect Tires:
- Check each tire for bulges, cracks, or foreign objects.
- Measure tread depth across the tire to ensure even wear.
Replace Tires (if needed):
- Remove lug nuts using a socket wrench.
- Remove the affected tire and replace it with a new or properly balanced tire.
- Reinstall lug nuts by hand, then torque to manufacturer's specifications (usually around 80-100 ft-lbs).

3. Wheel Balancing

Balance Tires:
- Mount the tires on a wheel balancing machine.
- Add wheel weights as necessary to achieve balance.
- Reinstall balanced tires back onto the vehicle.

4. Suspension and Alignment Check

Inspect Suspension:
- Visually inspect control arms, bushings, and shocks for wear or damage.
- Replace any worn components following proper procedures.
Perform Wheel Alignment:
- Use an alignment machine to adjust the angles of the wheels to manufacturer specifications.
- Adjust camber, caster, and toe settings as necessary.
