Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to secure the vehicle.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the lug nuts using a socket set and take off the tires.
2. Inspect tire tread depth and sidewalls for uneven wear or damage.
3. Replace any damaged tires with new ones, ensuring they match the specifications.
4. Reinstall the tires and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Balancing

Sub-steps:
1. Mount each wheel on a wheel balancer.
2. Spin the wheel to identify heavy spots.
3. Add balancing weights as required to both sides of the rim.
4. Recheck the balance until it meets specifications.

4. Wheel Alignment

Sub-steps:
1. Position the vehicle on an alignment rack.
2. Adjust the camber, toe, and caster angles to manufacturer specifications.
3. Test drive the vehicle post-alignment to ensure it tracks straight.

5. Inspect and Repair Suspension Components

Sub-steps:
1. Visually inspect suspension components for wear or damage.
2. Replace any worn or damaged components (e.g., bushings, tie rods) with OEM parts.
3. Reassemble and check for proper installation.
