Broken Rear Diff

[Raptor720]

Hi guys. I took out my savage today, it was running like a dream. I ran it out in my driveway with a few jumps, and then i noticed that the two rear wheels werent recieving any power. I haven't opened it up yet but i can see the dogbones are fine. When i spin one wheel the other isnt spinning. I think the diff/diff gears broke. I haven't worked on diffs yet so i would be open to tips and advice. I also would appreciate any other suggestions that could have caused the problem. Thanks.

Check the little grub screws that hold the drive cup to your transmission and one at your diff. It's common that they back out. If so replace and loc-tite

Best possible issue is you have lost the set screw for the input drive cup.
(Lol I was slow typing this out)

Blue Loctite is your best friend , I always remove any screw going into metal and a dab of loctite and reinstall.....

I kept losing a drive cup screw on this cheap (key word here) nitro buggy I was given, even with loctite. So I ca glued it in, still lost that screw.
