Carrier bearing is the bearing between the front driveshaft and the rear. Any time a 2 piece drive shaft is removed it should be balanced, like a tire removed from a wheel. That's probably your problem. Had that issue on my old s10.
Fokken hate 2 piece driveshafts. I'd get a 1 piece made imo.
I know what it is, Just don't know how to tell if it's bad lol. I hate my 2 piece. Mostly because it's all rusty and shit. I want a polished one piece
