I need to change the differential lubricant of my Durango but don't know the capacity and how I can drain and fill it afterwards. Should I use a "goose-neck" container for filling? I am planning to use AMSOIL 7.5W-90 Synthetic long life. (FGRQT).

Thanks in advance.

You'll need a wrench or ratchet, something flat to pry with, a catch pan, RTV Black (and preferably the actual pan gasket), a 3/8 or 1/2 flexible tube and three bottles of the gear oil. Your owner's manual will give you capacities in the reference section.

Slide under the rear end with your tools and accessories. Loosen the top 2 bolts but leave them in by a thread or so. Remove the rest. Insert the prying tool between the cover and the bottom of the differential housing and carefully break the seal to allow the old fluid to drain. When the flow slows down, remove the last 2 bolts and the cover. Clean the cover thoroughly with a rag and toss the rag in the garbage. It will never come anywhere near clean again. Completely clean the old gasket from both surfaces. Apply a 1/8 bead of RTV black to both surfaces and put the gasket in place on the pan if you bought one. Reinstall the pan and torque the bolts to about 20 lb-ft of torque. Refill the differential. Drive it for about an hour, let it cool and check the level by inserting your little finger (CAREFULLY) into the filler opening. If it comes back with oil to the first knuckle, you're good. If below, add more.
