Solution

1. Tire Inspection

Sub-steps:
- Measure tire pressure using a tire pressure gauge and adjust to manufacturer specifications.
- Inspect tread depth using a tread depth gauge; replace tires if worn unevenly or below safe levels.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a lug wrench.
- Mount the wheels on a wheel balancer; spin to identify imbalances.
- Attach wheel weights as needed; recheck balance after adjustments.

3. Suspension Inspection

Sub-steps:
- Visually inspect control arms, bushings, and struts for signs of wear or damage.
- Replace any worn or damaged components with OEM or high-quality aftermarket parts.
- Torque all fasteners to manufacturer specifications.

4. Driveshaft Examination

Sub-steps:
- Inspect the driveshaft for bends or cracks; replace if damaged.
- Ensure that all mounting hardware is secure and that the driveshaft is properly aligned.

5. Wheel Alignment

Sub-steps:
- Use a wheel alignment machine to measure alignment angles (camber, caster, toe).
- Adjust alignment settings to fall within manufacturer specifications.
- Test drive the vehicle to confirm the correction.
