Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, tire rotation tool, wheel balancer.
Raise the vehicle using a floor jack and secure it on jack stands. Ensure the vehicle is on a flat surface.

2. Tire Inspection and Pressure Adjustment

Sub-steps:
- Remove each wheel and inspect for uneven wear or bulges.
- Measure tire pressure and inflate to the manufacturer's recommended PSI if low.
- Rotate tires if uneven wear is present to promote even wear across all tires.

3. Wheel Balancing

Sub-steps:
- Mount the wheel on a wheel balancer.
- Spin the wheel to identify imbalances.
- Add wheel weights as necessary to achieve balance according to specifications.

4. Suspension Component Inspection

Sub-steps:
- Inspect control arms, bushings, and tie rods visually for cracks or excessive wear.
- Replace any worn or damaged components, ensuring all fasteners are torqued to factory specifications.

5. Driveline Inspection

Sub-steps:
- Check the driveshaft for any signs of bending or damage.
- Inspect U-joints for play; replace if any movement is detected.
- Ensure all connections are secure and free from rust or corrosion.

6. Wheel Alignment

Sub-steps:
- Use an alignment machine to check all angles (camber, caster, and toe).
- Adjust settings to meet manufacturers' specifications as necessary.
