Serviceable alternator?

Serviceable alternator?
So, i noticed a different 'pitch' coming from under the hood. I'm under the impression that the alternator bearing is on its way out.
Upon looking for a new idler pulley, and tensioner - which i couldn't find on rockauto, i stumbled upon a bearing for this particular alternator.
Now to affirm my belief, SKF [the maker] has the same part number listed for the other 1mz alternators - yes, i know they're the same.
Would it be 'dumb' to buy just the bearing? It doesn't look too bad to get into the housing from a diagram i saw. It states that its 'drive end bearing' so where the belt attaches to.
What would you suggest?
I want to get on this asap, and will make a choice tomorrow. I'd like a new alternator, but damn, they've gotten pricey on these cars - 150$ for a new one... before shipping. And used as little as 30$
So a new bearing at 30$, leads me to believe its the better call overall as the alternator works fine, as it should, just the bearing.
Thanks in advance

They did this on Wheeler Dealers for the E39 M5 that they bought. The job doesn't seem too difficult as long as you have a bench vice and a pulley puller.
Check it out, it's a fun show. The alternator part starts at exactly the 22 minute mark.

You will likely need a bearing press to do the job. Your brushes may also need to be replaced, and the commutator probably has wear grooves in it. You should verify it is the alternator, easy to do put a long screwdriver up against he body of the alternator and press it to your ear. If you have long hair, for the love of god make sure it does not get caught up in the moving parts.

If you want to replace the bearing you should do a complete overhaul of the alternator. For what its worth put a reman alternator in the car....no real sense trying to replace only some internals. The savings isn't there for how much work you would have to put in...unless you're a re-builder.
Spin the pulley's by hand without the belt on to determine if it is in fact your alternator making the noise.

Are there any differences at all or does it fit perfectly like the 80 amp one?
