Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery if electrical work is involved.
Safety warning: Allow the vehicle to cool down before working on tires.

2. Tire Rotation

Loosen lug nuts on all wheels while the vehicle is still on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the wheels and inspect them for damage.
Rotate the tires according to the manufacturer's recommendations (e.g., front-to-back or cross-rotation).
Reinstall the wheels, tightening the lug nuts to the specified torque (often around 80-100 ft-lbs).

3. Wheel Alignment

Take the vehicle to a professional alignment shop.
Have the technician perform a four-wheel alignment.
Adjust the camber, caster, and toe settings as per the manufacturer's specifications.
Test drive the vehicle to ensure alignment is correct.

4. Suspension Inspection

Check all suspension components for visible wear or damage.
Replace any worn out parts such as bushings, shocks, or struts as necessary.
Follow manufacturer specifications for torque values when reinstalling parts.
