Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Tire Inspection and Rotation

Sub-steps:
1. Remove all four tires using a socket set.
2. Inspect tires for uneven wear, bulges, or damage.
3. Rotate tires to different positions (e.g., front to rear) to see if the vibration changes.
4. Reinstall tires and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Balancing

Sub-steps:
1. Mount each wheel on a wheel balancer.
2. Identify any imbalance and add wheel weights as needed.
3. Confirm that the wheel is balanced correctly before reinstalling.

4. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Inspect struts, shock absorbers, and bushings for signs of wear, leaks, or damage.
3. Replace any worn or damaged components as necessary.
4. Reassemble any components and lower the vehicle.

5. Driveshaft and CV Joint Check

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
2. Check CV joints for grease leaks or wear.
3. Replace any damaged driveshaft or CV joint as needed.
