Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turned off.
Gather necessary tools and parts.
Safety gear: gloves and safety glasses.

2. Inspect and Replace Drive Axles

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove the wheels to access the drive axles.
3. Visually inspect the drive axles for any signs of damage or wear.
4. If damage is found, use a socket set to remove the drive axle nuts.
5. Carefully pull the drive axle out of the hub and replace it with a new one, ensuring proper alignment.
6. Reinstall the axle nut and torque it to the manufacturer's specifications.

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. With the wheels still removed, check the wheel bearings for play or roughness.
2. If the bearings are worn, use a bearing puller to remove them from the hub assembly.
3. Install new bearings using a press or appropriate tool, ensuring they are seated properly.
4. Reattach the wheel assembly and torque to specifications.

4. Test Drive

Take the vehicle for a test drive to verify that the noise has been eliminated and ensure the vehicle is performing correctly.
