Steps
- Position a catch pan and open the plugs
Park on level ground and place a drain pan beneath the differential. Confirm the fill plug can be removed first, then loosen the drain plug and let the old gear oil empty completely.
- Clean and reinstall the drain plug
Clean the drain plug and its threads, and wipe the housing threads free of debris. Apply the correct thread sealant if required, then reinstall the drain plug and tighten it to the vehicle specification.
- Fill the differential
Load the transfer pump with the specified gear oil and pump it through the fill opening. Continue until oil reaches the lower edge of the opening, allowing excess to settle before closing the plug.
- Close the fill opening and check for leaks
Clean the fill plug and housing threads, apply sealant only if required, and reinstall the plug to specification. Wipe the differential clean and inspect around both plugs for seepage after a short drive.
Check your vehicle’s repair manual for exact specifications and fit.
