Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the tires are properly inflated.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire’s pressure.
Inflate or deflate tires as necessary to reach the manufacturer’s specified pressure found in the owner’s manual or on the driver’s door jamb.

3. Wheel Alignment

Tools Required: Wheel alignment machine
Adjust the alignment settings based on the manufacturer's specifications:
- Set camber, toe, and caster angles to the specified values.
- Tighten all adjustment bolts to the manufacturer’s torque specifications.

4. Suspension Inspection and Repair

Inspect suspension components:
- Replace any worn or damaged parts such as bushings, struts, or control arms.
- Follow manufacturer guidelines for any replacement parts in terms of specifications and torque settings.

5. Tire Rotation and Replacement

Rotate tires if uneven wear is detected but not extreme.
- Move front tires to the rear and rear tires to the front.
- If wear is too severe, replace affected tires with new ones.

6. Recheck and Final Adjustments

After adjustments, recheck tire pressures and alignment.
Ensure all tools are removed from the vehicle.
