Solution

1. Preparation

Ensure the vehicle is parked on a flat, level surface.
Disconnect the 12V battery to prevent any electrical issues during the repair.
Gather all necessary tools and parts.

2. Drain Differential Fluid

Locate the differential drain plug and remove it using a socket set.
Allow the fluid to completely drain into a suitable container.
Inspect the drained fluid for metal shavings or other contaminants.

3. Inspect and Replace Differential Components

Remove the differential cover if necessary to inspect internal components.
Check the ring and pinion gears for wear or damage.
Inspect the differential bearings for signs of wear; replace if necessary.
If components are damaged, replace them with OEM parts.

4. Clean and Reassemble

Clean the differential housing and cover thoroughly, removing old gasket material.
Install a new gasket or sealant as per manufacturer specifications.
Reassemble the differential cover and tighten bolts to the specified torque value (consult service manual for specific torque specs).

5. Fill Differential with New Fluid

Use the recommended differential fluid (consult the owner's manual for specifications).
Fill the differential through the fill plug until fluid begins to seep out.
Reinstall the fill plug securely.
