Yeah, and when I was looking for a rebuilt alternator, I found the majority of the alternator rebuilds take place in the same factory in China. Bosch does all their alternator rebuilds, including those sold to BMW as OEM replacements, in that factory. I think Delco does too. If you want well made bearings and diodes and whatnot, you need to search out the few remaining local small alternator and starter rebuild shops. Or source the parts and rebuild them yourself. I decided to pay the local guy to do it hoping to help keep him in business.
