metal on metal sound coming from the rear of my jeep

There is a metal on metal sound coming from the rear. It sounded like the gears were going bad so I put new gears in it today and the sound is still there I can't figure it out. It is loudest when I'm pressing the gas. I can't figure it out. Thanks in advanced for the help.

Brakes hanging up, or bearings going bad, would be my guess.

Bad e-brakes or pinion/carrier/axle bearing . From what you say , pinion is my thought .

What gears ? C&P or spider ?

That's a tough one . Did you check the u-joints . I'm doubting you missed much connected to the diff rebuild . Everything I can think of was exposed during the work , u-joints , having to pull the axles . The e-brakes were also in plain view .

You did the side axle bearings also ? Just confirming

Times like this you need those "mouse" ears . They stick on parts(magnet) and measure noise levels .

Yes replace all bearings and about A month ago I replaced all my u joints on both front and rear drive shafts. And after I was done I cleaned and adjusted the teaser breaks. And is been making this noise for a while now.

It was lifted when I got it and it was not making the noise when I got it.

I have 3.75 offset wheels so it won't do that. I can't figure this noise out.
