Solution

1. Tire Inspection and Maintenance

Sub-steps:
- Check tire pressure using a tire pressure gauge; inflate to manufacturer specifications.
- Inspect tire tread depth with a tread depth gauge; replace tires if tread is below recommended levels.
- Rotate tires if uneven wear is present; follow the manufacturer's recommended rotation pattern.

2. Wheel Alignment

Sub-steps:
- Use a wheel alignment tool to measure alignment angles.
- Adjust camber, toe, and caster as necessary to bring the wheels into alignment.
- Re-test alignment after adjustments to ensure specifications are met.

3. Suspension Component Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect shock absorbers and struts for leaks and wear; replace if necessary.
- Check control arms and bushings for signs of damage or excessive play; replace as needed.

4. Drivetrain Inspection

Sub-steps:
- Visually inspect the driveshaft for any signs of damage or imbalance.
- Check CV joints for wear or excessive play; replace if necessary.
- Tighten any loose bolts or fasteners related to the drivetrain components.
