Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, and an OBD-II scanner for any error codes.
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection

Sub-steps:
- Remove the wheel covers if applicable.
- Inspect the tires for any bulges, cracks, or uneven wear patterns.
- Use a tire pressure gauge to check and adjust tire pressures to the recommended PSI.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the tires on a tire balance machine.
- Adjust weights on the wheel as needed to achieve balance.
- Reinstall the wheels on the vehicle and torque the lug nuts to manufacturer's specifications (typically around 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Place the vehicle on an alignment rack.
- Follow the equipment's instructions to check all alignment angles (camber, caster, and toe).
- Adjust alignment settings to meet manufacturer specifications.

5. Suspension Inspection and Repair

Sub-steps:
- Inspect shocks, struts, and other suspension components for leaks or physical wear.
- Replace worn or damaged components as necessary.
- Reassemble any parts that were removed for access.
