I bought an entire rear carrier out of a wrecked jeep on the auction website. And had it installed. It sounded so bad I figured it was entirely ruined. So I thought it best to replace the whole thing. 300 for the part and 365 to put it in.
I should mention it's a ZF made unit which I think is mercedes. And there were 3 carrier bearings this was from the smallest one closest to the driveshaft.
