Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the tire pressure on all tires.
Inflate or deflate each tire to the manufacturer-recommended pressure (typically found on the driver’s door jamb).

3. Tire Rotation

Loosen the lug nuts on the tires using a lug wrench.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove the tires and rotate them according to the vehicle’s recommended pattern (e.g., front to back, side to side).
Reinstall the tires and tighten the lug nuts to the manufacturer's specified torque.

4. Wheel Alignment

Take the vehicle to a professional alignment shop.
Ensure a four-wheel alignment is performed, adjusting camber, caster, and toe settings to manufacturer specifications.

5. Suspension Inspection and Repair

If any suspension components are found to be damaged or worn during the visual inspection, replace them as necessary.
Common components to check include control arms, bushings, and ball joints.
Reassemble any disassembled suspension parts and perform a final inspection.
