Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and ensure it is secured with wheel chocks.

2. Tire Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate tires as needed to match the recommended PSI found in the owner’s manual or on the driver’s door jamb sticker.

3. Tire Rotation and Inspection

Sub-steps:
- Remove the tires using a socket set.
- Inspect the tread for uneven wear and replace any tires that are excessively worn.
- Rotate the tires according to the manufacturer's recommended pattern.
- Reinstall the tires and torque the lug nuts to the specified torque value (typically around 100-110 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Set the vehicle on a wheel alignment machine.
- Adjust the camber, caster, and toe angles to the manufacturer’s specifications.
- Perform a test drive to ensure the alignment is correct and the wandering issue is resolved.

5. Suspension Component Replacement (if necessary)

Sub-steps:
- If any worn or damaged components are found during the inspection, such as tie rods or bushings, replace them as needed.
- Follow manufacturer specifications for installation and torque settings.
