Another question!!

what gear oil is needed for the front and rear diffs, and the tcase???
Engine oil in the transfer case. I go ahead and use the recommended 5w-30

Service manual sez you can use either 75w-90, 80w-140 or 80w-90 in the diffs, depending on the temperature range. I like the 80w-90, seems to get me faster coasting travel in the rear wheel bearings.
