Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure vehicle is parked on a flat surface and secure the vehicle with wheel chocks.
Use jack stands to lift the vehicle safely.

2. Tire Inspection and Repair

Sub-steps:
1. Remove all four wheels using a socket set.
2. Inspect each tire for wear, bulges, or uneven tread wear.
3. If any tire is damaged, replace with a new tire of the same specification.
4. Check tire pressure using a tire pressure gauge and inflate to the recommended PSI.

3. Wheel Balancing

Sub-steps:
1. Mount tires on a tire balancing machine.
2. Spin each tire to identify heavy spots.
3. Add balancing weights to the rim as necessary to achieve balance.
4. Reinstall balanced tires onto the vehicle.

4. Suspension and Alignment Check

Sub-steps:
1. Inspect suspension components (ball joints, tie rods, control arms) for play or damage.
2. Replace any worn components as needed.
3. Use an alignment machine to check and adjust wheel alignment as per manufacturer specifications.
