So I just installed a 9" last month consisting of Moser housing and axles, a stock Ford case & TracLoc, Motive 4.11s, and Richmond bearing/rebuild kit. I set everything up myself including the gears, and got a very good pattern at the end. The car was silent up until about 400-500 miles after the install. I did a proper breakin with about 10 good heat cycles on it before I hit the highway or anything fast. At about 250 miles I did give it some wide open pulls, but no hard shifting, just feeling the gears and slowly shifting.. At maybe 450, it got some good highway runs I changed the fluid at about 600 miles with some Valvoline non-synthetic 80/140 to try and quiet it down as I have quite a bit of whine from about 30mph all the way up, well it didn't. When I drained the oil, I found metal chunks on the oil pan. I know people say some "metal shavings" will come out, but I consider this bigger than metal shavings. It definitely looks like gear metal. Is this excessive, or something to be very concerned with right now?

I'd pull the center section out and take a good look at it. Bob

definetly looks like you may have some chunks off of the teeth. and a good setup 9 inch should whine especially brand new with no runs on it

Check the casting around the rear pinion bearing support for cracks too. They crack there if You try to put some HP to a stock center section.

Man I really don't want to pull out the center section! I'll have to find a couple open days where I know I won't be driving. I can tell it's not case metal, because you can see the markings that are on the tips of gear teeth.
