BUSTED! Ring gear bolts, that is...
 
:mad: My "new" ride is a 2006 Unlimited with a softtop (had a hardtop; damn Pike County jumping trees...), long arm lift, 35" KM2's, axles regeared and E-Lockers installed. Wheeled several times, nothing radical as I like to finesse things when I can. Driving in town, I hear a "Pop", and pull into a parking lot. I don't see anything unusual and it drives normally. ?? I drive it on to my lady's home (about 10-12 miles) and smell the dead dinos when I get out. Fine oil droplets all over the rear end tells me to look at the pig and there's something that has tried to get out of there by poking a hole in the cover.
When I removed the cover, I discovered that five ring gear bolt heads had snapped off. Everything was properly torqued and locktited. There is evidence that there was a lot of heat somewhere along the line as in varnish on the carrier. Can anyone give me a clue as to what happened? :confused: And, is there an easy way to get the stubs out of the ring gear?

I can't help you, other than to suggest you really know how to tell a background story.

Well, take it a part, that is pull the carrier and ring gear out, then remove the remaining bolts holding the ring gear on and then you can get to the "stubs" and remove them...sounds to me like they were torqued down incorrectly, ie. in a star pattern...

I have read about this before and there are threads on it. We had a Jeep in our club do the exact same thing. Ended up needing to replace about every thing if I recall.

Thanks Doc! I'd already done a search on several different forms (including this one) with no results. Seeing your post, I tried again and Presto! Way more info than I can handle at this time of night (nearly Midnite, and I need my beauty rest...). It looks like my setup man may have used the wrong torque numbers which is strange, because he really sweats the small stuff and is a perfectionist. I'll discuss this with him and we'll get it back together. Ring and pinion look good, carrier (E-Locker) is scarred. Probably will replace all bearings to be safe. Maybe even get a set of bolts from the dealer to be sure we have good quality.

Thanks, Hustler for the kind words- many people think I'm a half a bubble off of plumb; I think that they have a problem... I may be old, but I don't drink prune juice on purpose!

I would think something from ARP.
