Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, socket set, alignment tool, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Adjust Tire Pressure

Check the recommended tire pressure from the manufacturer (found on the driver’s side door jamb).
If any tires are under-inflated or over-inflated, adjust them accordingly using an air compressor.

3. Rotate Tires

Loosen the lug nuts on all four wheels using a socket set.
Lift the vehicle with a jack and secure it with jack stands.
Rotate the tires according to the manufacturer’s recommended pattern (e.g., front-to-back or crisscross).
Reinstall and torque the lug nuts to the manufacturer’s specification (typically 75-85 ft-lbs).

4. Perform Wheel Alignment

Using a wheel alignment tool, adjust the camber, caster, and toe settings to the manufacturer’s specifications.
If adjustments cannot be made due to worn components, replace necessary parts (e.g., control arms or tie rods) before realigning.

5. Inspect and Replace Damaged Components

If any suspension components are found to be worn or damaged during the inspection, replace them as necessary.
Ensure all bolts are torqued to the manufacturer’s specifications.
