Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Safety warning: Disconnect the battery if working on electronic components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to the recommended PSI as indicated on the driver’s side door jamb.

3. Tire Inspection and Replacement

Remove each wheel using a socket set.
Inspect the tread for uneven wear; replace tires if they are worn beyond the manufacturer's specifications.
Reinstall the wheels and torque lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Wheel Balancing

On a balancing machine, mount each tire and wheel assembly.
Adjust weights as necessary to achieve balance.
Reinstall wheels after balancing and ensure lug nuts are correctly torqued.

5. Wheel Alignment

Use an alignment rack to measure the alignment angles of the wheels.
Adjust camber, caster, and toe angles to the manufacturer’s specifications.
Verify alignment with a test drive.

6. Suspension Inspection and Repair

Inspect all suspension components visually and by feel.
Replace any worn or damaged parts (tie rods, ball joints, etc.) using appropriate tools.
Follow manufacturer torque specifications for any nuts and bolts.
