You have to remove the rear cover on the differential housing. Once the fluid is all drained, replace cover with new gasket (or use silicone sealer) and refill through 3/8" square plug on the side of the unit.

One other point to this. Replacing the fluid can be a bit tricky. By the time you get yourself, your tools, and your bottle of fluid under the truck it can be a challenge to the fluid in the differential. To ease the problem, get a small section of hose to connect to the spout of the bottle and then run the other end into the differential and squeeze. It is pretty easy and faster.

The differential fluid on a Dodge Ram 1500 4x4 needs to be changed every 50,000 miles for normal highway driving. If the vehicle is used in 4x4 regularly, then change the differential fluid about every 25,000 to 30,000 miles.

If there is not a drain plug on the bottom of the differential then you will have to remove the cover. Be sure that you service it with the proper fluid and positraction additive if it is a positraction differential.

You must remove the big medal plate that is bolted to the back of the rear end housing to change the fluid.

The factory stock weight of a 1999 1500 4x4 Suburban is 5,226. A 4x2 only weighs 4,769. Modifications and added equipment, factory or not, will change this weight.

You have to take the differential cover off and an take clips off the two axles they slide right out
