9inch Rearend Destruction! Well went to replace third members because mine was howling and noisy as hell. Here is what I was putting in.
Found this!
WTF! LOL I knew I could break a bowling ball in a sandbox with a plastic hammer....but a 9inch on a stock motor???
LOL I found large needle bearing looking things in the mess prob 1/4" thick....I looked at old third member and it looks like
I broke something off of that...haha no wonder it made so much noise!
Just finally looked a little closer at old 3rd member and look what I found.
The pics aren't the best, needed better lighting, I will post more later.
Basically the entire thing was falling apart, not only was the case broke around pinion which is where the bearings came from,
but the locker has a massive crack going all the way around it, and the case itself was cracked at the bottom.
How this thing stayed together like this for 2+ years is beyond me, gotta hand it to Ford for a great design, even if it is a completely aftermarket version.
Looks like a bent axle caused vibration enough to make pinion nut back out and destroy all this from 2 years ago.
I kind of have doubts the axle is bent but we put the car on jackstands with the wheels off and noticed the driverside had a bit of a wobble to it.
I took it out and it looked ok by visual inspection but I know I wouldn't be able to tell that way unless it was ridiculous.
What causes bent axles?

Lol I guess I didn't mention it......It was a Moser housing and third member!
On top of that, its on a bolt on only car.
The car that had it before mine though was a 9sec car, but that was from 3 years or more back.
