Default Differential issues

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.

Check for stripped gears? And use a oil in the diff, Ofna puts this cheap thin grease.


I saw you on the SCR forums too, gotta get out there some time.

Could you be a bit clearer as to what "Screw" you're turning?

If you change the diff oil, you should be removing 4 screws from around the ring gear.

It's roughly a 4-5mm set screw on the side barrel of the diff.

I would take all the diffs apart and lube them they may just have grease in them. The screw you were tightening is just a fill/drain hole (dont use) tightening should change the diff action unless you are screwing it into a side gear I would try 5k 5k 2k for diff oils.

The set screw in the side of the diff case is there so you can remove the pin from the bevel gear shaft.

Speed bump it right. It is a screw for assy only. It is not an adjustment. Clean the diff out and replace the fluid with the appropriate fluids. Check for broken parts or wear while you are in there. That little screw should be flush with the outside of the case.
I run 3K - 5K - 2K in my Ofna car.
