Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Safety warning: Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Remove the wheels:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove lug nuts with a socket wrench and take off the wheels.
Inspect tires:
- Check for uneven wear and bulges.
- Replace tires if they are worn unevenly or damaged.
- Recommended tire pressure: Refer to the manufacturer's specifications.
Reinstall wheels:
- Place the wheels back on, hand-tighten the lug nuts, and lower the vehicle.
- Torque lug nuts to manufacturer's specifications (usually around 80-100 ft-lbs).

3. Suspension Inspection and Repair

Inspect suspension components:
- Examine shocks/struts for leakage or damage.
- Check control arms and bushings for wear.
Replace damaged components:
- Remove any faulty struts/shocks using a socket set.
- Install new struts/shocks and torque bolts to manufacturer's specifications.
Perform wheel alignment:
- Use a wheel alignment machine to adjust the camber, caster, and toe settings.
