Need help with my Muggy

[Unsullied_Spy]

I've recently had a really bad noise in my front diff. I thought I had stripped the ring and pinion but I pulled it out and it's in immaculate condition. There are no signs of wear, strippage, or slippage on the gears. I checked the wheel bearings, CVDs, wheels and hubs, etc. and everything looks good.

I've got some video showing what it sounded like. In the beginning the diff cup on the front diff pinion was loose, I thread-locked the screw and cranked it down as tight as possible but it that hasn't fixed it.



I took the front wheels off and set it the rear on the ground and hit the throttle a few times and it didn't make the noise.
