Help...once again

Which one is not working, going to assume the front went out on you. Check your wheel hexes along with you diff you could have stripped it when jumping.

Also check that the driveshafts are turning the diffs. I've lost a grub-screw and the front axle wouldn't pull the rig anymore.

Start spinning things, see where the motion stops.

Its actually the rear end
Its also weird that the braking failed too it wont break

It might be your rear diff. I've blown out a few, never had a problem with the front. Are you hearing or feeling any grinding or rough spots when you rotate the rear wheels?

Sounds like it could be your rear differential. Test this by putting the two rear wheels on the ground and spinning the spur gear, if the two front wheels spin, then it is the rear differential, does it feel "crunchy"?
