Alternator going bad?

Alternator going bad?
About 6 months ago or so my alternator started squealing when I hit a certain rpm. Since that time I thought it was going bad but I never had the money to get a new one. My battery stays charged, I don't have any power loss (I have 2 subs and my speakers amped). I was talking to my dads friend tonight and he said my alternator has dirt in it (I do take my truck out and play in the mud) and to get this electrical spray and clean it out.
Think that is the problem or is it slowly going out?

Sounds like your dads friend is right. Spray it out and see if it goes away it may or may not work depending on how far the crud has worked it's way into the alt.. If it doesn't go away you may have to pull it and open it up and spray it out. If you have to do that check the front and especially the rear bearing for play. If you find play in the bearings you could go to an auto electric shop and have them put a new bearing in it or depending on your capabilities you might be able to do it yourself.

i doubt there is anything in your alternator, or that spraying it with anything will make a difference. an alternator is an electric motor, with a stationary field and a rotating armature and a thin air gap between them. any water or mud would get slung out. any mud left behind on the stationary parts is not going to make any noise.
more likely you have a bad bearing on the pulley end of the shaft. the only thing that will quieten it down is a new bearing (or a rebuilt alternator).

Like DV and 2nd gen said, it's a pissed of bearing that you are hearing. It sucks. I know. I'm dealing with one right now, and it's embarrassing when you stomp the throttle and the rpms spike into the 3000 range, and that low growl of the Flow masters is fouled by this sound in the engine bay. Reminds me of someone trying to strangle a chipmunk. I spray mine down with a silicone lube every now and then, but once it cooks off, it comes back. I'm waiting for it to seize and torch the belt at the same time.
