Yup, sounds like gear noise for sure, especially if its only in decel.. If the backlash at the pinion/ring gear is incorrect it will definitely make noise either accelerating or decelerating.
Chances are that the flange is OK and its wobbling is due to the bearing issue. Unless the flange itself shows evidence of damage (unlikely)
Thanks for reply,
Any idea about pinion depth and backlash? Will I need to adjust them after replacing the bearing ?

Yes.Thanks for reply,

Differential heats up and makes noise. Change the fluid and see what happens.When driving highway speeds for a while
All this talk of laud differentials. I installed this
View attachment 80338
And a set of these

And now it sounds like there is a dump truck in my back seat. Is that normal?
You might try removing ring & pinion. On small 90* air grinder and using a 2" dia. 80 grit disc chamfering all edges on both the R & P removing the sharp corners which I think might be causing the gears to scream. I am planning on doing this on my 06 GT but haven't gotten around to it.
So I replaced all the bearings in differential, and now i get some different, high pitched noise while decelerating.Yes.

Just the pinion rolling resistance.preload
Can I still tighten it without taking the carrier out ?Just the pinion rolling resistance.
You can’t measure the pinion preload “rolling resistance “ if it is turning the carrier also. You have to pull the carrier and rotate the pinion with an inch/ounce torque wrench.carrier out ?
If you can move the pinion side to side, aka feel some play, than it is too lose and you can tighten it. But VERY carefully, just until that play is gone. Correct torque is just past that point. Too tight and pinion bearings will burn up.Can I still tighten it without taking the carrier out ?
