Solution

1. Preparation

Tools Required: Socket set, fluid pump, differential fluid (as specified in owner’s manual), clean rags.
Safety Warnings: Ensure the vehicle is on a level surface and securely lifted with jack stands.

2. Drain Old Fluid

Remove Fill Plug: Using a socket wrench, remove the fill plug to allow air in.
Drain Plug Removal: Place a drain pan under the differential and remove the drain plug. Allow fluid to completely drain.
Inspect Drain Plug: Clean the drain plug, check for metal shavings or debris. Replace if necessary.

3. Inspect and Clean

Clean Differential Housing: Wipe down the area around the drain and fill holes to prevent contamination.
Inspect Gasket: Check the differential cover gasket for wear or damage. Replace if needed.

4. Fill with New Fluid

Attach Fluid Pump: Connect the fluid pump to the differential fluid container.
Fill Differential: Pump new differential fluid into the fill hole until it begins to overflow. This indicates that the differential is full.
Replace Fill Plug: Securely replace the fill plug, ensuring it’s torqued to manufacturer specifications.
