Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Use wheel chocks and jack stands when lifting the vehicle.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate any under-inflated tires to the recommended PSI as indicated on the driver’s door jamb.

3. Tire Rotation

Remove the wheel covers or hubcaps if equipped.
Loosen the lug nuts slightly (do not remove them) while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and tires, then rotate front tires to the rear and rear tires to the front, ensuring the left and right tires switch sides.
Reinstall lug nuts and tighten them to the manufacturer's torque specification (typically around 80-90 ft-lbs).

4. Wheel Alignment

Take the vehicle to a professional alignment shop.
Ensure the alignment is set according to the manufacturer's specifications, adjusting camber, caster, and toe as necessary.

5. Suspension Inspection and Repair

If misalignment persists, inspect the suspension components for wear.
Replace any damaged or worn parts, such as tie rods or control arms, using the appropriate tools (socket set, torque wrench).
Recheck the alignment after any suspension repairs.
