- Inflate or deflate tires to reach the recommended pressure listed on the door jamb.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using a jack and lug wrench.
- Place the wheel on a balancing machine to identify heavy spots.
- Add wheel weights as necessary to balance the wheel.
- Reinstall the wheel and torque lug nuts to the manufacturer's specifications.

4. Wheel Alignment

Sub-steps:
- Drive the vehicle onto a wheel alignment rack.
- Adjust the alignment angles (camber, caster, toe) according to manufacturer specifications.
- Test drive the vehicle to confirm proper alignment.

5. Suspension Inspection

Sub-steps:
- Visually inspect shock absorbers, struts, and bushings for wear.
- Check for play in ball joints and tie rods.
- Replace any damaged components as necessary.

6. Driveline Check

Sub-steps:
- Inspect the driveshaft for any visible damage or excessive play at the u-joints.
