1. This procedure should be performed after the vehicle has been driven, so the lubricant will be warm and therefore will flow out of the differential more easily.
2. Raise the vehicle and support it securely on jack stands. You’ll be draining the lubricant by removing the drain plug, so move a drain pan, rags, newspapers and wrench under the vehicle. Remove the check/fill plug.
3. Remove the fill plug and drain plug and allow the lubricant to drain into the pan, then clean and reinstall the drain plug. Tighten the plug securely.
4. Using a hand pump, syringe or squeeze bottle, fill the differential housing with the specified lubricant until it’s level with the bottom of the fill plug hole.
5. Install the plug and tighten it securely. Drive the vehicle a short distance, then check for leaks.
6. The old lubricant drained from the differential cannot be reused in its present state and should be disposed of. Check with your local auto parts store, disposal facility or environmental agency to see if they will accept the lubricant for recycling. After the lubricant has cooled it can be drained into a container (capped plastic jugs, topped bottles, milk cartons, etc.) for transport to one of these disposal sites. Don’t dispose of the lubricant by pouring it on the ground or down a drain!
