there was a guy that machines his own piece that bolts on to where the input shaft goes into the diff that is supposed to strengthen the case and stop them from breaking. this thread talking about it was recently posted im sure if you searched the forum you can find the link in one of the posts

Ya we have few buddies and were actually considering that option since OEM is cast I'll see if I can find it. I'm pretty new to this site so I'm sure it'll take awhile. How about aftermarket differential is there any out there I've googled with no success

Mine broke when I rolled over a drift and tires left the snow maybe 4". Not much so I personally don't think it should of snapped and brother in law was having issues with 4x grabbing he was going through some powder in 2 wheel and it grabbed and it popped. I've read of plenty other guys breaking them too. No I don't jump or do wheelies in 4 wheel
