Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to secure the rear wheels.

2. Tire Pressure Check

Use a tire pressure gauge to measure the pressure in each tire.
Inflate any under-inflated tires to the recommended PSI as specified in the owner’s manual.

3. Tire Inspection

Remove the wheel covers if applicable.
Check for uneven tire wear; replace tires if tread depth is significantly different across the tire.
Rotate tires if uneven wear is found to help balance the vehicle's handling characteristics.

4. Alignment Procedure

Place the vehicle on an alignment rack.
Adjust the toe, camber, and caster settings according to manufacturer's specifications.
Perform a final check to ensure all settings are within the recommended range.

5. Suspension Inspection and Repair

Visually inspect all suspension components for cracks, bending, or excessive wear.
Replace any damaged or worn components such as control arms or bushings.
Tighten all suspension bolts to specified torque settings.
