Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, alignment tools, wrenches, and a torque wrench.
Ensure the vehicle is on a flat surface and the ignition is off.

2. Tire Pressure Adjustment

Using a tire pressure gauge, check the pressure of all tires.
Inflate or deflate tires to the recommended pressure (found on the driver’s door jamb).

3. Tire Inspection

Remove all four tires using a lug wrench.
Inspect tread depth and wear patterns; replace tires if they show uneven wear.
Rotate tires if necessary to promote even wear.

4. Suspension and Steering Check

Inspect control arms, ball joints, and tie rods for any visible damage or excessive play.
Replace any worn or damaged components as needed.

5. Wheel Alignment

Using alignment tools, adjust the toe, camber, and caster to the specifications provided in the vehicle’s service manual.
Tighten all bolts to the manufacturer's torque specifications.

6. Test Drive

Reinstall tires and torque lug nuts to specification.
Lower the vehicle and perform a test drive to ensure that the wandering issue has been resolved.
