Solution

1. Preparation

Gather tools and parts.
Tools Required: Jack and jack stands, socket set, torque wrench, fluid pump, OBD-II scanner.
Parts Required: Differential oil, gasket sealant (if applicable), replacement differential if severely damaged.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported by jack stands before working underneath.

2. Inspect and Replace Differential Fluid

Remove the differential cover or drain plug using a socket set.
Allow the old fluid to completely drain into a catch pan.
Inspect the old fluid for metal shavings or debris, indicating internal wear.
Clean the differential housing and replace the gasket or apply gasket sealant if needed.
Refill the differential with the correct type and amount of fluid (refer to the owner's manual for specifications).

3. Inspect Differential Components

With the vehicle still lifted, check for excessive play in the differential and driveshaft.
Look for signs of damage, such as worn bearings or gears.
If components are damaged, proceed to remove the differential.

4. Remove and Replace Differential (if necessary)

Disconnect the driveshaft from the differential by unbolting it.
