Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential fluid fill and drain plugs.
2. Remove the drain plug and allow the old fluid to drain completely.
3. Inspect the fluid for metal shavings or discoloration.
4. Replace with new differential fluid (refer to the owner's manual for specifications).
5. Reinstall the drain plug and torque to the manufacturer’s specifications.
6. Refill the differential using the fill plug until fluid begins to seep out, then replace the fill plug.

3. Inspect CV Joints and Axles

Sub-steps:
1. Remove the wheel from the affected side.
2. Inspect the CV joint and boot for any tears or leaks.
3. If damaged, remove the axle nut and disconnect the CV joint from the hub.
4. Replace the CV joint/axle as necessary.
5. Reassemble by reversing the removal process and torque the axle nut to specifications.

4. Inspect Differential Mounts

Sub-steps:
1. Check the differential mounts for any signs of wear or damage.
2. If mounts are worn, replace them with new parts.
3. Ensure all mounting bolts are torqued to the manufacturer's specifications.
