Inspect the differential fluid level and condition using the fill plug.
2
Check for any visible leaks or damage around the differential housing.
3
Listen for noise changes when turning or accelerating to determine if noise is related to load changes.
4
Raise the vehicle and manually rotate the driveshaft to feel for roughness or binding.
5
Scan the vehicle for any related diagnostic trouble codes (DTCs).

Solution

Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Tools Required: Jack, jack stands, socket set, torque wrench, fluid pump, OBD-II scanner.

2. Check Fluid Level

Locate the fill plug on the differential.
Remove the fill plug using the appropriate socket.
Check if the fluid is at the correct level (should be at the edge of the fill hole).
If low, add the manufacturer-recommended differential fluid until it reaches the appropriate level.

3. Inspect for Damage

Visually inspect the differential housing for cracks or signs of impact.
Examine the differential mounts for any signs of wear or damage.
Check the output shafts for play or movement.

4. Replace Differential Fluid (if necessary)

If the fluid is dirty or contaminated, drain the old fluid by removing the drain plug.
Allow the fluid to fully drain, then replace the drain plug.
Use a fluid pump to add new differential fluid through the fill plug until it overflows slightly, indicating it is full.
Reinstall the fill plug and torque to the manufacturer specifications (typically around 30 ft-lbs).

5. Test Drive

Lower the vehicle and perform a test drive to see if the noise persists.
Pay attention to any changes in noise during acceleration and turning.
