Rock Krawler any good?

When I got my Jeep to get back off road after being out of it for a few years, I checked out all the Jeep forums I could find.
I settled here at Wayalife, and it has become my Jeep family. Sometimes things go off track, but the knowledge and top flight information is better than all the others with many competing opinions and no way to know good from crap.
If someone posts something here that is not good, it gets called out for what it is. Sometimes it gets a bit overboard, but the point is that crap doesn't get by and cause people problems.
Hey, you broke a Dana 80. I'm not surprised at anything you might be able to break after that. Obviously you play harder than most.

A difference of opinion is, “getting torched?”

If it’s not the same as yours that’s usually what it leads to

Where have you posted anything that is proof?

Or you could just tell us the story of how it happened.... Breaking a ProRock 80 isn't like getting a flat tire or anything like that.

No cool story. As far as I know I broke it in Disney at the big meat run. Didn’t know it was broke until I got it back to the shop and was doing some maintenance(rebuilding Johnny joints
) and coilovers and bypass’s and a broken rcv. Had the rear end out and decided to pull the cover to change the fluid and 
broken ring gear.Attachments

Does this help my opinion? How many do you count? I damn sure didn’t pull them all apart and rebuild them for the fucking fun of it. These were rebuilt right before the Disney run and then getting rebuilt right before the palo duro Jeep challenge with a hand full of local wheeling trips in between.

If your really tearing it up like that, why not just Swap them to an FK Hemi joint? I’m guessing it’s mostly the rears going out due to HP and heavy foot.

The Fab work looks good!
On the broken ring gear, it looks like the pinion walked in a bit under load based on the tracks on the carrier.
Did you find out why it did?
Was a crush sleeve or a solid spacer used?
I ask because I have seen crush sleeves collapse under extreme load, letting the pinion walk in and out, throwing the set up out the window, leading to a broken ring gear. Not on a Dana 80 mind you, but the mechanics of it would be the same.
