How can you freshen up the alternator?
With 150k miles, I am pretty sure the next to go out will be the alternator. I already did a tune up by replacing spark plugs and also replaced the belts. Can you replace just the brushes and internal regulator on the alternator? Where can you get parts?
I am trying to catch up on my preventive maintenance.

You dont normally freshen up an alternator, it's usually run until it has problems, this is one of those parts that could run for 20 miles or a million miles you cant ever tell wich it'll be untill you get there.
But if you really want to do preventive maintenance look up electrical shops in your area there should be someone that rebuilds alternators.
Check the price on remanned alternators while your at it, they may be cheaper.

Yeah, I just watched an episode of Wheeler Dealers where the mechanic opened up a noisy alternator and replaced the bearings. Other than that and a few electronic components, an alternator is just a big ball of wound copper wire. Not a ton of parts to replace, really...I like you.

You might be able to find a local rebuilder to get the parts from or have them do it if you don't have the tools

I went to the site and checked the parts look up.
It looks like I have to identify which alternator I have from the 3 listed.
1. Bosch alt - 125 amp
2. Declso opt. - 130 amp
3. Delco std. 105 amp
The regulator is $26.20
Brush holder is $5.90
Bearings> $2.70 and $4.10 for front and rear 6202 and 6203.
Anybody knows how to identify my alternator?

You should definitely take pictures as you do the rebuild. It would make for a great tutorial and DIY walkthrough for the forum! I'd love to read it, anyway... Or, at least post a good narrative on the process, telling us about the harder and easier spots.
