Since the TRX gears are only 2 spiders it takes really thick oil to get the same action as 1/8th diffs. I had to use 500K oil in the center diff in the revo, it was like toothpaste. Still diffed out too lol.

I filled the 500K like paste. Filled the dif cup up, rotating the gears as I went along. Then put on the crown gear and let it leak out one of the screws. I tried several ways, but none are too easy.
