What you think? Pulled it because it was super whiny on partial throttle and quite coasting. Measured back lash and it was about .020”

The fluid seem very shiny!

Put a magnet in the fluid and just a marble size of gunk stuck to it! Lots of metal sludge in the oil! Very little miles on this....No more than 250 miles
Certainly doesn't seem right to me. Maybe the gears had a poor heat treatment.
Andrew
I just don’t feel like pulling mine again
The wear patterns look good; backlash and pinion depth seem to been set up properly. I'd change the fluid and look again in another 250 miles. Perhaps this is break-in wear?
Possibly the solution to noisy 9” Ford!

Is US Gear made by Strange?
That's interesting. They don't mention anything about sound, but looks like a good alternative? Maybe those gears with the treatment from GearFX will do the trick?
I'm interested in this because I'm looking at the 9 inch as a possibility for my car and the only complaint I find is about gear noise. Don't hear about that with the 12 bolt...
Those gears are specifically advertised to be quite. Claimed to have "hobbing" like I heard OEM gears were. That gear set also has a REM finish option under the lightning series. It seems very promising that gear set will be quite and the REM service will make them the ultimate street gear in noise and performance.

Agree - wear pattern looks ok to me and the sludge is likely clutch break in. But the noise isn’t good. Can you put on a louder exhaust ? Haha
Again identical situation as mine and Three of my other buddies with a dse moser Ford 9”. Mins got better after replacement gears but not perfect, another you can faintly hear and another that’s perfect after new gears
Just an update on this. Moser did end up swapping the gear for me.
but did it fix it?
I sure hope so. I got the isotropic finish on this gear and indeed the backlash was over 2x spec on the old gear. The new gear is at .009 and feels firm. I decided to put floater ends on the housing since it’s all disassembled, so soon to come and see if it makes noise.
