I've never changed the diff fluid from stock on my Ofna buggy( my center diff seemed VERY loose). I took the rear gearbox and center out today to have a looky. There's a single allen screw on the diff themselves. When tightening, it seems to ass tension and tighten up the diff (if I kee going it's like positive traction). Should I only be concerned with fluid chang or simply adjust that screw until the diff (mainly the center) reacts better? As it stood before, I could spin the right front wheel and get a very slow reaction from the left front. I got NO reaction from the rear wheels. Also, should I use any locktite on that screw, as there didn't seem to be any on there to begin with.(perhaps that's why my center diff was so loose?)
Thanks for helping.
