I recently replaced the alternator in my Saab with a Mexican rebuilt for $115 from RockAuto, and prior to that I always bought rebuilt alternators from my local parts store. From my own experience working at an auto parts store I know there is a huge markup on rebuilt parts. My Dodge Ram is approaching 90k miles and I'm thinking about doing some proactive maintenance in the near future, to include cooling system flush, t-stat, water pump, and serpentine belt. While I have the belt off I might as well pull the alternator too. I saw an online video of a guy rebuilding the Bosch alternator from a Dodge Ram and it looked ridiculously easy. Didn't find a rebuild kit for that alternator, but I found a source for the bearings. If I can find the voltage regulator maybe I'll try to rebuild it myself. Anybody here rebuild a Bosch alternator, or any alternator?
