Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Check and Replace Differential Fluid

Tools Required: Socket set, fluid pump, container for old fluid.
Remove the differential fill plug using a socket wrench.
Insert a fluid pump into the differential and extract a sample of the fluid for inspection.
If the fluid is dirty or low, drain the old fluid by removing the drain plug.
Allow the fluid to fully drain into a container.
Replace the drain plug with a new gasket; torque to manufacturer specifications.
Refill the differential with the recommended fluid type until it reaches the fill level, and replace the fill plug.

3. Inspect and Replace Components

Tools Required: Jack and jack stands, socket set, pry bar.
Safely lift the vehicle and secure it on jack stands.
Inspect the CV joints and axle shafts for signs of wear or damage.
If any components are damaged, remove the affected axle shaft using a socket set and replace it with a new part.
Reinstall any removed components and ensure all bolts are torqued to specification.

4. Test Drive and Final Checks

After reassembly, lower the vehicle and conduct a test drive to ensure the noise has been resolved.
Monitor for any leaks or unusual noises during the drive.
