Solution

1. Tire Inspection and Balancing

Sub-steps:
1. Check tire pressure using a tire pressure gauge; adjust to manufacturer specifications.
2. Inspect for uneven tire wear or damage (bulges, cracks).
3. If tires are damaged, replace them.
4. Remove the wheel and mount it on a wheel balancer; adjust weights as necessary to achieve balance.

2. Suspension Inspection and Repair

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Inspect control arms, bushings, and struts for signs of wear or damage.
3. Replace any worn components with OEM parts.
4. Tighten all bolts to the manufacturer’s torque specifications.

3. Driveshaft and CV Joint Check

Sub-steps:
1. Inspect the driveshaft for any signs of bending or damage.
2. Check CV joints for proper lubrication or any torn boots.
3. Replace or repair any damaged parts as needed.
4. Ensure all connections are secure and torque to specifications.
