1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather safety equipment such as gloves and safety glasses.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for bulges, cracks, or uneven wear.
- Measure tread depth; replace tires if tread is below 2/32 inches.
Replace Tires if Necessary:
- Loosen lug nuts with a socket set.
- Use a jack to lift the vehicle and remove the tires.
- Install new tires and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Balancing

Remove Wheels:
- Use a socket set to remove the wheels from the vehicle.
Balance Wheels:
- Take wheels to a professional tire shop for balancing.
- Ensure weights are properly placed to eliminate vibrations.

4. Suspension Inspection and Repair
