I posted a video a few months ago about a random noise that I thought was coming from the top end of the motor, like, maybe the CCT... well, now I'm pretty sure it's the alternator. I put my hand on the alternator and when I hear the clack/clunk noise, I feel it through the alternator casing. What kind of skill level are we talking about to rebuild/fix that? Can I do it with just a manual and the proper tools? Or is this one of those "you should really have someone help you with the first one" kind of thing?
