This is why I hate ball diffs. You have to crank the crap out of them, to the point of snapping the diff bolt, to get them to stop slipping.

Good to hear. If you like it now, you'll love it on Lipo.

Yep, I've snapped one original bolt. Now I just pack them with grease and use my imaginary torque wrench to tighten it down.

Using the proper grease in a ball diff is the most crucial part to making them live. If you just use "normal" grease even when cranked will still slip.

Proper diff grease isn't slippery as it's designed to let the balls bite into the ring and not slip. If you use normal grease the balls tend to slide on the rings and destroys the whole thing. Naturally you tighten the diff further to stop the slipping but you just create more pressure and heat.
