Solution

1. Preparation

Gather tools and materials: jack, jack stands, tire pressure gauge, socket set, torque wrench, and safety goggles.
Disconnect the battery to ensure safety while working on the vehicle.

2. Tire Inspection and Replacement (if necessary)

Check tire pressure using a tire pressure gauge; inflate to manufacturer’s specifications if low.
Inspect tires for uneven wear, bulges, or foreign objects; replace if damaged.
Rotate tires if uneven wear is detected to balance wear patterns.

3. Drivetrain Inspection

Raise the vehicle using a jack and secure it on jack stands.
Visually inspect the driveshaft and CV joints for any visible damage or signs of leakage.
If damage is found, remove the affected driveshaft or CV joint:
- Use a socket set to remove bolts securing the driveshaft to the transmission and rear differential.
- Carefully pull the driveshaft out and replace it with a new part, ensuring to torque bolts to manufacturer specifications.

4. Suspension Component Inspection

Examine all suspension components for wear, including control arms, bushings, and struts.
If any components are found to be defective, replace them:
- Use a socket set to remove bolts securing the affected components.
- Install new components and torque to manufacturer specifications.

5. Wheel Bearing Inspection and Replacement (if necessary)

Spin each wheel to check for roughness or noise.
If wheel bearings are suspected to be the cause, remove the wheel and brake assembly.
Use a bearing puller to remove the old wheel bearing, and install a new one, ensuring proper alignment and torque.
