Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working.

2. Fluid Inspection and Replacement

Tools Required: Socket set, torque wrench, fluid pump, differential fluid.
Sub-steps:
1. Remove the differential fill plug using a socket set.
2. Check the fluid level; if low, drain the differential fluid using a fluid pump.
3. Inspect the fluid for metal shavings or a burnt smell, indicating potential internal damage.
4. Replace the differential fluid with the recommended type (typically 75W-90 gear oil).
5. Reinstall the fill plug and torque it to manufacturer specifications.

3. Component Inspection and Replacement

Tools Required: Jack and jack stands, socket set, pry bar.
Sub-steps:
1. Lift the vehicle securely and remove the wheels if necessary for better access.
2. Inspect the CV joints and axle shafts for wear or damage.
3. If damage is found, remove the axle shaft by unscrewing the bolts at the differential and hub assembly.
4. Replace with new axle shafts or CV joints as necessary.
5. Reinstall all components and torque to specifications.

4. Test Drive

Tools Required: None.
Sub-steps:
1. Reconnect the battery.
2. Lower the vehicle back to the ground.
3. Conduct a test drive to confirm that the noise has been resolved.
