Hey all!

My water pump went and took out the bearing on my alternator at the sasme time... So figured insted of just buying a new alternator I'd try replacing the bearings and maybe the brushes while im in there. Problem is I cant find an answer on what sizes to order. Lots of info for 3rd gen but nothing for 4th.

I have a 5.7l hemi in a 2012 1500 sport in case anyone wants to give a guy a hand.

Your probably going to need to mic it to get the correct size.

That's what I'll do if I have to. I just know that somewhere, out there, is someone with the plans and info I need.

If the bearings spun then you would need to sleeve it and that wouldn’t be cost effective unless you have access to a machine shop, you’ll be better of just replacing the whole assembly if they spun but if not than it is cheaper to rebuild.

There is a video of a guy doing it on youtube LINK but maybe I'm wrong... either way seems like a fun project to at least try.
