Your owners manual will give you all this information you need and the quantities for refilling. The front and rear axles take 75-90 weight gear oil for both the front or rear. Actually takes a bit less than 2 qts for the refill but I just dump the whole two bottles. As far as the transfer case, I can't help you much on that. I know some G.M transmissions take Dexron, so you may have to find your owners manual for the correct fluid for your transfer case fill.


Also the rear and front differential covers have a reusable gasket that can be reused without using any gooey silicone either. Just torque down and you won't have any leaks. If you have the desire to use silicone don't use it with the G.M gasket.
