Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, wheel alignment tool, tire pressure gauge.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels for access to suspension components.

2. Tire Pressure Adjustment

Sub-steps:
- Check each tire's pressure using a tire pressure gauge.
- Inflate or deflate tires to the recommended pressure (found on the driver's door jamb).
- Reinstall the tires and lower the vehicle.

3. Wheel Alignment

Sub-steps:
- Using the wheel alignment tool, check and adjust the alignment settings.
- Ensure that toe, camber, and caster are within manufacturer specifications.
- Use a torque wrench to tighten any suspension bolts to the manufacturer’s specified torque values.

4. Suspension Inspection and Repair

Sub-steps:
- Inspect suspension components (control arms, bushings, tie rods) for wear.
- Replace any worn or damaged components as necessary.
- Reassemble any components that were disassembled for inspection.

5. Test Drive

Conduct a test drive to confirm that the wandering sensation has been resolved.
Monitor for any abnormal noises or behaviors during the drive.
