Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is securely lifted on jack stands.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Drain Differential Fluid

Tools Required: Drain pan, 10mm socket, torque wrench
Remove the drain plug using a 10mm socket.
Allow the old differential fluid to completely drain into the pan.
Inspect the drained fluid for metal shavings or debris which indicates internal wear.

3. Inspect and Clean Components

Tools Required: Clean rags, flashlight
Inspect the differential housing for cracks or damage.
Clean the drain plug and ensure the magnet (if equipped) is free of debris.
Remove any debris from the differential housing and around the fill hole.

4. Replace Differential Fluid

Parts Required: Differential fluid (check manufacturer specifications for type and capacity)
Reinstall the drain plug and torque to manufacturer specifications (usually around 30 lb-ft).
Fill the differential with new fluid using the fill plug until it reaches the proper level (fluid should be just below the fill hole).

5. Replace Seals (if necessary)

Tools Required: Socket set, seal puller, gasket scraper
If leaks are present, remove the old differential seals.
Clean the sealing surfaces thoroughly.
Install new seals according to manufacturer guidelines, ensuring proper orientation.

6. Reassemble and Lower Vehicle

Reinstall the fill plug and torque to specifications.
Reconnect the negative battery terminal.
Lower the vehicle safely from jack stands.
