Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Safety warning: Always wear gloves and goggles when working on vehicles.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure in each tire.
Inflate tires to the manufacturer's recommended pressure (found in the owner's manual or on the door jamb).

3. Wheel Alignment

If misalignment is suspected, take the vehicle to a professional alignment shop.
Adjust the camber, caster, and toe angles according to the manufacturer’s specifications.

4. Suspension Inspection

Remove the front and rear tires using a socket set.
Visually inspect control arms, tie rods, and shock absorbers for any signs of wear or damage.
Replace any worn components as necessary.

5. Tire Rotation

Rotate the tires according to the manufacturer's recommended rotation pattern (typically front-to-back or side-to-side).
Reinstall tires and ensure they are torqued to the manufacturer’s specifications (usually 80-100 ft-lbs).
