A few weeks ago I change my diff becasue bearings made so much noise. I bought used diff from a car that had like 150k km on it. Everything seemed to work fine for like 500km. Once I was going back home I made a quick downshift to 3rd gear and I heard one knock from rear. And then when I try to pull away I hear two or three knocks from the rear. I checked the diff and mounts and everything has been fine.

I even checked the driveshaft universal mount and it seemed okay. I had it exchanged like 40k km ago. The clutch, engine mounts and transmission mounts had been exchanged too.

Might it be a driveshaft center bearing? I didn't check it because it would take lots of time.

Or the diff I bought turned out to be just a shit?

Motor or trans mount.
