Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles.

2. Tire Inspection

Sub-steps:
1. Check tire pressure with a gauge; inflate to the recommended PSI if low.
2. Inspect tires for bulges, cuts, or uneven wear patterns.
3. Rotate tires if uneven wear is detected to promote even wear.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels using a socket set.
2. Mount the wheels on a balancing machine.
3. Add weights as necessary to achieve proper balance.
4. Reinstall the wheels, ensuring they are torqued to the manufacturer’s specifications (typically around 100-120 Nm).

4. Wheel Alignment

Sub-steps:
1. Position the vehicle on an alignment rack.
2. Use alignment equipment to measure camber, caster, and toe angles.
3. Adjust the suspension components as needed to bring angles within specifications.
4. Confirm alignment with a test drive.

5. Suspension Inspection

Sub-steps:
1. Visually inspect struts, shocks, and bushings for signs of wear or damage.
2. Test suspension components for play or looseness.
3. Replace any worn components as necessary.
