Detroit Locker street habits & problems

This is a little confusing to explain, but here goes:
My original D35 with Warn 5 on 5.5 floaters, 4.11's and a Detroit, as best as I remember, behaved on the stree like any other detroit, ocassional pulling to one side, some loud engagements etc... but nothing that I remembered to be unusual.

As I wheeled more and more, the housing got pretty bad bent, seals wouldnt live long at all, no bearings ever failed though, and street manners got worse and worse.

Specifically, it started to quickly and unexpectedly jerk to the right, the whole jeep would just swerve 1-1.5 feet to the right and a popping/engaging sound would come from the rear diff(every now and then it would pull to the left). When it first started, it only did it every now and then. As it got worse I figured a new housing and the Superior Axle truss would cure the problem.

Now after the housing, truss, new R&P (shop said mine was worn out & installed a new one under warranty) the problem seems worse!! I have no idea what is wrong.

When I pulled the original bent housing out, popped the diff cover, there was a ring gear bolt loose in the housing, it was pretty chewed up from getting pinched in the gears, and several other bolts could be loosened by hand!! Shop had no explanation.

The shop said the new gears were kinda hard to set up (whatever?) but I am worried about the bolts in the new setup, If they are loose will that cause the excessive sideways jerking motion? It normally will do it twice in a row, about twenty seconds apart. It does it after a section of curvy road, and in long straight aways, other than the jerking it operates perfectly.

What other bad manners do you guys have with Detroits? This can't be normal? I plan on removing the superior truss to inspect, but what other advice do ya'll have?

My alingment is kinda old, would that do it? It dosen't pull, DW or vibrate too bad. Ball joints are about dead though.
 
Did you look at your locker real close? Sounds like what my lockright does in my CJ. Not as severe, but banging and changing lanes every once in a while. I have a detroit in my 8.8 and don't even know it is there. As far as ring gear bolts, they didn't locktite them, that's why they came out. My bro had the same problem on his YJ, one bolt actually came out and wedged itself between the pinion and housing. Bent the pinion so it wouldn't spin 360 degrees. Anyway, sounds like your locker is damaged.
