Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure and inflate to manufacturer specifications if low.
2. Inspect tires for uneven wear patterns; replace tires if worn unevenly or beyond legal limits.
3. Rotate tires if uneven wear is detected to promote even wear.
Tools Required: Tire pressure gauge, tire removal tools.

2. Wheel Balancing

Sub-steps:
1. Remove the wheel from the hub.
2. Use a wheel balancer to check for imbalances.
3. Add or remove weights as necessary to achieve balance.
4. Reinstall the wheel and torque lug nuts to the specified values.
Tools Required: Wheel balancer, torque wrench.

3. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect the shocks and struts for leaks or physical damage.
2. Check bushings and mounts for wear; replace any damaged components.
3. If any parts are found defective, remove and replace with new components.
Tools Required: Socket set, jack stands, suspension tool kit.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft and axles for any signs of damage or excessive play.
2. If damage is found, remove the affected component and replace it with a new part.
3. Ensure all drivetrain components are properly aligned and secured.
Tools Required: Socket set, jack stands, torque wrench.
