Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a level surface.
Use a jack and jack stands to lift the front of the vehicle safely.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate any under-inflated tires to the recommended pressure (check the driver's side door jamb for specifications).

3. Inspect Tires

Remove any hubcaps or wheel covers if necessary.
Visually inspect the tread on all tires for uneven wear (e.g., cupping, bald spots).
Rotate tires if uneven wear is detected and replace if necessary.

4. Perform Wheel Alignment

Using an alignment machine, measure the alignment angles (camber, caster, toe).
Adjust the toe settings to meet factory specifications.
Document any adjustments made.

5. Inspect Suspension and Steering Components

Check for damaged control arms, tie rod ends, and bushings.
Replace any worn or damaged components as needed.

6. Test Drive

Lower the vehicle back to the ground.
Conduct a test drive to confirm the repair.
