Solution

1. Preparation

Gather tools and parts required for alignment and inspection.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to match the manufacturer's recommended pressure (found in the owner’s manual or door jamb).

3. Tire Inspection

Remove the wheel covers (if applicable) using a flathead screwdriver.
Inspect each tire for uneven wear or damage, such as bulges or cuts.
Replace any damaged tires as necessary.

4. Wheel Alignment

Place the vehicle on a professional alignment rack.
Adjust the toe, camber, and caster settings according to the manufacturer's specifications.
- Toe: Typically between 0.1° to 0.2° outward.
- Camber: Usually between -0.5° to -1.5° depending on vehicle specs.
- Caster: Usually between 2.5° to 5.0° depending on vehicle specs.
Tighten all adjustment bolts to the manufacturer's torque specifications.

5. Suspension Inspection

Inspect all suspension components for signs of wear or damage, such as cracked bushings or loose bolts.
Replace any worn or damaged components to ensure proper alignment and handling.
