Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, tire pressure gauge, wheel balancer, alignment machine.
Safety Warnings: Ensure the vehicle is on a level surface and secure with jack stands before working underneath.

2. Tire Inspection and Pressure Check

Tire Inspection:
- Remove each wheel using the lug wrench.
- Inspect for bulges, cracks, or uneven wear.
Tire Pressure:
- Check and adjust tire pressure to the recommended PSI listed in the owner’s manual.

3. Wheel Balancing

Mount each tire onto a wheel balancer.
Spin the tire to identify any heavy spots.
Add wheel weights as necessary to achieve proper balance.

4. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
Perform a test drive to confirm alignment adjustments.

5. Suspension Component Inspection

With the vehicle lifted, inspect struts, shocks, and control arms for any play or damage.
Replace any worn or damaged components, reassembling with proper torque specifications (typically around 30-80 ft-lbs, depending on the component).
