Transfer case lubricant change (4WD models)
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 transfer case more easily.
2. Raise the vehicle and support it securely on jack stands.
3. Remove the filler plug from the case (see illustration).
The drain plug (A) and fill plug (B) are on the rear of the transfer case
4. Remove the drain plug from the lower part of the case and allow the lubricant to drain completely.
5. After the case is completely drained, carefully clean and install the drain plug. Tighten the plug securely.
6. Fill the case with the specified lubricant until it is level with the lower edge of the filler hole.
7. Install the filler plug and tighten it securely.
8. Drive the vehicle for a short distance and recheck the lubricant level. In some instances, a small amount of additional lubricant will have to be added.
9. The old lubricant 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!
