Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection

Sub-steps:
- Remove the wheel covers if applicable.
- Inspect each tire for uneven tread wear, cracks, or bulges.
- Check tire pressure and adjust to the manufacturer’s recommended specifications.

3. Wheel Balancing

Sub-steps:
- Remove the tires from the vehicle.
- Mount each tire on the balancing machine and spin to check for imbalance.
- Add wheel weights as needed to balance each tire properly.
- Reinstall the tires on the vehicle, ensuring correct torque specifications (typically around 90-120 ft-lbs).

4. Alignment Check

Sub-steps:
- Using an alignment rack, check the camber, caster, and toe settings.
- Adjust the alignment to meet manufacturer specifications if any measurements are out of range.

5. Suspension Inspection

Sub-steps:
- Inspect control arms, bushings, and ball joints for damage or excessive play.
- Replace any worn or damaged components as needed.
- Recheck wheel alignment after repairs.
