An important parts vendor nomenclature thing:
I see websites claiming things like OEM, OEMS, rebuilt and/or remanufactured.
It's the later that gets my ire most of the time. I'm old school and besides being BMW trained, I'm also Bosch trained. Back when Bosch actually was a magnificent company, they sold "remanufactured" alternators, starters, injection pumps etc. The process of methodically rebuilding everything and/or installing (most often) completely new parts inside was magnificent. So much so, that a new part had a 12 month warranty and the reman part had a 24 month warranty. Most often to include free towing. Unheard of at the time.
FF to the 21st. century and those terms are tossed around very easily so you......buy the parts from them.
I dare say that 90% of the racks out there are just "Rebuilt" and not "Remanufactured". The former being a teardown, inspection, new seals and out the door.
Out there anymore I currently have two choices to offer my customers: A dealer rack, which most of the time (If/when available ??) is usually remanufactured. Albeit at a dealer price threshold.
Then the Bosch rebuilt racks, of which I've had decent luck with so far.
You're wise asking here. Experience is a good teacher. There's a lot of such here in the collective.
Hate: Remanufactured moniker applied incorrectly. Rant OFF.
