Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and parts.

2. Tire Inspection

Sub-steps:
- Remove any wheel covers or hubcaps.
- Visually inspect all tires for uneven wear patterns, bulges, or cuts.
- Measure tire tread depth to ensure they meet minimum safety standards.
Tools Required: Tire pressure gauge, tread depth gauge.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount each wheel on a tire balancing machine.
- Add weights as needed to balance the wheel according to the machine's readings.
- Reinstall balanced wheels on the vehicle, ensuring proper torque specifications (typically 80-100 ft-lbs).
Tools Required: Tire balancing machine, torque wrench.

4. Wheel Alignment

Sub-steps:
- Take the vehicle to an alignment rack.
- Adjust the alignment angles (camber, caster, toe) to factory specifications.
- Perform a test drive to confirm that the steering wheel is centered and the vehicle tracks straight.
Tools Required: Wheel alignment machine.

5. Suspension Inspection and Repair
