Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Rotation

Remove the wheel covers or hubcaps if applicable.
Use a socket set to loosen and remove the lug nuts on the affected wheels.
Inspect the tires for uneven wear patterns or visible damage (e.g., bulges, cracks).
Rotate the tires to ensure even wear if necessary.
Reinstall the lug nuts and tighten them to manufacturer specifications (usually 80-100 ft-lbs).

3. Wheel Balancing

Mount the tires on a wheel balancing machine to identify any imbalances.
Add wheel weights as needed to achieve proper balance.
Reinstall the balanced tires onto the vehicle.

4. Suspension Inspection and Repair

Inspect the suspension components, including control arms, bushings, and struts for wear.
Replace any damaged or worn suspension parts using appropriate tools.
Torque all bolts to manufacturer specifications.

5. Driveshaft and CV Joint Inspection

If applicable, inspect the driveshaft for any signs of damage or excessive play.
Check CV joints for torn boots or grease leakage.
Replace any damaged components as needed.
