Solution

1. Tire Inspection and Balancing

Sub-steps:
1. Remove each wheel using a lug wrench.
2. Inspect tires for bulges, cuts, or uneven tread wear.
3. Balance the wheels using a tire balancer machine.
4. Reinstall the wheels and torque lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

2. Suspension Component Inspection

Sub-steps:
1. Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
2. Replace any worn components as necessary.
3. If components are found to be in good condition, verify that they are properly tightened using a torque wrench.

3. Driveshaft and CV Joint Inspection

Sub-steps:
1. Raise the vehicle on a lift or jack stands for access to the undercarriage.
2. Inspect the driveshaft for any noticeable bends or play.
3. Check CV joints for torn boots or excessive movement.
4. Replace any damaged driveshaft or CV joints as needed.
