There is a grind going on somewhere in the front when driving. I can't find where it's coming from and sounds like metal to metal. I checked the front diff it was good and even removed the front drive shaft and was still there.
The thing is its grinding goes away when I hit my breaks And when I'm turning. So I can only hear it when accelerating and coasting.
The breaks don't seam out of wack besides needing to be replaced soon. And the hubs were just replaced not too long ago. Any help on what it is would be great. 97 i6 242 transfer case

We'll not my hubs. My axle shafts are fine. Replaced my brake pads.

Still getting the noise. Not sure where to go. But it seems to be coming from my differential. But when I opened it up it seemed fine and nothing seemed outta place. Then again I'm no gear expert.
What could be coming from there but go away when I hit my brakes that's why I'm so b

Pinion bearing? Do you have a full time case? If so pull the front DS and see it that changes it.

Edit: Theres a procedure to run without shafts so you can confirm that it's the diff, time to take it to somebody who knows diffs, or call it DOA and swap in a JY axle.

Even w/o the drive shaft that pinion gear is still rotating. It could still be making noise even w/o a front ds

I didn't have any up/down or side to side movement in the yolk on the diff. Everything seemed tight any other way to check pinion?
