Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, alignment machine
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and replacement parts if needed.

2. Tire Inspection and Pressure Adjustment

Sub-steps:
1. Remove the hubcaps if applicable.
2. Use a tire pressure gauge to check each tire's pressure.
3. Inflate or deflate tires to the recommended pressure found on the driver's door jamb.
4. Inspect each tire for uneven wear patterns that may indicate alignment issues or suspension problems.

3. Wheel Alignment

Sub-steps:
1. Drive the vehicle to an alignment shop or set up an alignment machine.
2. Follow the machine's instructions to check the alignment settings (camber, caster, toe).
3. Adjust the alignment according to manufacturer specifications, typically:
  - Front toe: 0.0° to 0.1° (in)
  - Rear toe: 0.0° to 0.2° (in)
4. Recheck alignment after adjustments to confirm settings are within tolerance.

4. Steering and Suspension Check

Sub-steps:
1. With the vehicle on jack stands, inspect the steering components (tie rods, rack and pinion).
2. Check for any play in the ball joints, bushings, and control arms.
3. Tighten any loose fasteners to manufacturer specifications.
4. Replace any worn or damaged parts as necessary.

5. Test Drive

After completing the repairs, take the vehicle for a test drive to ensure that the wandering issue has been resolved.
Monitor steering response and overall handling on both straight and curved road sections.
