well i had my 9" installed thursday with 4.11's detroit lockers and 35 spline with all new rear end suspension (everything is adj on all suspension)...
i keep hearing a clunking noise when i put it into gear (and when i shift from any gear to anyother0 ... and at about 70 when i let off the gas i kinda got a clunk and a small wine... and i keep getting a horrible vibration at all speeds..
now heres the kicker dunno what you guys think but let me know.. the old man and i got under there and started pissing around with it...
my torque arm on the top adjustable is as tight as you can get it to the mount... on my lower control arms none of my bolts that are adj it where tight... when i grabed ahold of the drive shaft it moves damn near an inch if not more with the e brake pulled and it in nutral (now would that be a problem i would have to send the third member back to moser for?)... and on the control arms should i be able to grab ahold of them and twist them when there bolted in place? i just got off the phone with my buddy that put everything in and he is going to take good care of me and fix the loose stuff and is takeing 100% of the blame for that now im just worried about the noise's...
thanks, josh

The locker will seem like it has a lot of backlash, that is normal with it. Lockers do exhibit a lot of clunking which is normal with them, and a little bit of whine is normal with aftermarket gear sets.
You should have no vibrations though, I would first check the pinion angle.
Setting the pinion angle can be found at this BMR link.

Yup, clunking, clicking, popping and lurching to one side are normal for a locker. Vibration is not so normal but of course you have to get the loose parts bolted up right and the pinion angle set properly. And, if you have a locker then you need the limited slip additive in the gear oil.

i understand the noise from the locker 100%.. i just cant explain it i got three buddies of mine that have the same rear end.. same everythhing just 4.33's not 4.11's... and there backlash is no where near mine... when they put it in gear every once in a while you get a clunk but not anywhere near the loudness or anything as mine is... and none of them have the clunking whinning type noise when you let off the gas that i do...
its just freaking me out.... cause i ride in there cars or drive them alot so im use to the locker but i got in mine and its just plain old violent... nothing like any of theres...

Well the only one I have driven was mine, and it was horrible like you are describing. It's a long story but basically I bought it used and it was supposed to have a Truetrac in there but had a Locker and I believe this was done by mistake. I got it swapped out to a Truetrac and everything is good but I suspect that the reason it was so bad before is because it did not have the required LSD additive for the Locker. Does your rear end have the LSD additive?
