Solution

1. Tire Inspection and Repair

Sub-steps:
1. Remove the wheel covers (if applicable) and inspect tires for bulges, cracks, or foreign objects.
2. Measure tire pressure and inflate to the manufacturer’s recommended PSI.
3. If damage is found, replace the tire with a new one.

2. Wheel Balancing

Sub-steps:
1. Use a wheel balancer to check the balance of each tire.
2. Add wheel weights as necessary to ensure proper balance.
3. Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs, check specific model).

3. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the control arms, bushings, and tie rods for signs of wear or damage.
3. Replace any worn components with OEM or high-quality aftermarket parts.

4. Wheel Alignment

Sub-steps:
1. Place the vehicle on an alignment rack.
2. Measure the alignment angles and adjust as necessary to meet manufacturer specifications.
3. Perform a test drive to ensure the vehicle drives straight without pulling to one side.
