Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to match the recommended PSI found on the driver’s door jamb.

3. Tire Inspection and Replacement

Remove the wheels using a lug wrench.
Inspect each tire for uneven wear or damage.
Replace any damaged tires with new ones, ensuring they are of the correct size and type.

4. Wheel Balancing

Mount the tires on a wheel balancer.
Identify and correct any imbalances by adding wheel weights as necessary.
Reinstall the balanced tires back onto the vehicle.

5. Wheel Alignment

Use an alignment machine to check the alignment specifications.
Adjust the camber, caster, and toe settings to meet manufacturer specifications.
Tighten all bolts and retest the alignment.

6. Suspension Inspection and Repair

Inspect control arms, ball joints, and bushings for signs of wear.
Replace any worn or damaged suspension components using appropriate replacement parts.
Reassemble all components and ensure all fasteners are torqued to specification.
