Loud metallic bang sound from new 9" w/Detroit Locker.
Ok guys so I installed a Moser 9" with 4.11's and a Detroit locker(31 spline). I was supposed to get a tru trac but there was a mix up somewhere and got a locker instead. So no big deal, I can deal with the noises and what not. But this thing is absolutely rediculous.
Fist thing is when I'm turning and giving it gas it will make the usual clicking noises that a locker will make, but every so often it will make a god awful metallic banging sound. Its not the drive shaft hitting the exhaust, or the T/A hitting the body. It is definately coming from the left side somewhere. Also taking off slowly on flat straight ground it will make these same sounds. Now I know what a locker sounds like, and acts like, this thing is definately not acting right.
It is almost like a broke axle or somthing. Has anyone else had problems with the detroit like this? What exactly is there in there to break? Springs maybe? I'm confused. I havent pulled the 3rd yet, will be doing that sometime this week. Just trying to get some insight from guys with a detroit locker...sorry for the long post, thanks!

What is happening is that the dog clutch is not releasing smoothly from spider and center cam assembly for what ever reason when turn slightly or hard turning. This will also happen from a stop if the dog clutch is not engaged into the spider and center cam assembly prior to moving forward. This noise will be amplified due to all the clearance that is built into the locker for proper operation. If you got the owners manual you can troubleshoot it prior to disassembly. If not you can download it from Eaton.
If it is doing it all the time then you probably do have a concern.

Mine does this tank sound as well. For example, when the rear is in the air or on blocks and I spin one tire or wheel, it will rotate just a bit then it hit or catch something that sounds like a metal thud and it locked and will not move anymore.
Also when I put the car in gear, it will make a thud or bang. It has done that since day one out of the box.
My guess is it is not perfectly lined up inside and it catches or releases.
I saw a post where Bob said that he did a launch at the track without warming the tires, when he lauchned the locker broke. I guess it was off just a bit and not locked.

It was a GTO that we had at the old shop installed a Moser fabricated nine inch, along with a torque arm, lower control arms, etc. We took it to the LSX Shootout two years ago and Brent did the driving. He heated up the tires and pulled up to the line, and apparently the locker wasn't engaged because when he went to launch the car it broke the pinion on the starting line. It didn't hurt the PST driveshaft or anything else, just snapped the pinion off. Bob
