Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, impact wrench, wheel chocks.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery if necessary for safety.

2. Tire Inspection and Balancing

Loosen the lug nuts on the affected wheel(s) while the vehicle is on the ground.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel and inspect the tire for bulges, cracks, or uneven wear.
If tires are damaged, replace them.
Use a tire balancing machine to balance the tires. Reinstall the wheels and torque lug nuts to specifications (usually 80-100 ft-lbs).

3. Suspension and Alignment Check

Visually inspect suspension components (struts, shocks, bushings) for any signs of wear or damage.
Replace any worn components as necessary.
Perform a wheel alignment using an alignment machine, adjusting camber, caster, and toe as per manufacturer specifications.

4. Driveshaft and CV Joint Inspection

Inspect the driveshaft for any noticeable bends or damage.
Check the CV joints for any tears in the rubber boot or grease leakage.
If damage is found, replace the driveshaft or CV joint as needed.
