I saw this video online: http://www.youtube.com/watch?v=fS_BL1b2wns
The video is helpful, but it only shows one bearing being replaced. Isn't there at least 2? Does anyone know how the drive side bearing is replaced?
What bearings would you all suggest I order to replace the existing ones? I was looking at these (http://www.bikeman.com/BB1692.html) but honestly have no idea if that is a good bearing or a good price.
I have Campagnolo freehub, but it is less than one year old (switch from Shimano to Campy late last year) so I am thinking the bearings in it are fine.
If anyone could clarify those few points I would really appreciate it.
I was looking online, and there are a ton of "ceramic bearings" with a huge price range:

Can anyone help clarify which are good, which are bad, etc...? I want to get good bearings, but don't want to spend more than I need to.
Thanks in advance.

The Powertap hubs are machined so there is no type of adjustment. If the hub is machined incorrectly, there is too much load on the sides of the bearings which caused mine to fail [as little as 100 miles to totaly seized by 300 miles]. They did not agree with my opinion and since I am just a consumer with no engineering degree, it took awhile to convince them it was not me but the hub. A new hub did fix my bearing issue but a year later, I was generating +1400 watts [and 300 watts while coasting]. They have them now and getting fixed.
The service dept. at Cycleops is fine. They have treated me with respect, listen to my frustrations, and have calmed me down after a frustrating weekend with a seized rear wheel. I would not buy another SL+ hub, but because of their service, may look into their newer hub design [it can't be worst could it?].
dhendriksen... don't spend a lot on bearings... it's a waste of money.
So, I have a gift card to Amazon and figured why not use it for this. I'm looking at this bearing: http://www.amazon.com/S6902-2RS-Ceramic ... 02+Bearing" onclick="window.open(this.href);return false;
I am going to need two of them, right? And if I understand it, those two are for the drive train side? What do I need on the NON drive train side? If it makes a difference, I have Campagnolo.
So I tried an old trick for lazy guys: I just pulled out the outer seal and sprayed the hell out of the two hub bearing with WD-40. I blasted the crap out of them to get rid of any dirt. Spinning and blasting with WD-40 until they felt a little cleaner.
Then, allowed them to dry a bit, repacked them solidly with Phil Wood Grease and zipped to whole thing back up. I didn't touch the cassette body bearings.
But they are still far less than "perfectly smooth" so I guess I'll get some bearings on order and plan a project for early autumn.
You can press the drive side bearing in using a threaded rod with the olf bearing and some large washers...Pretty straight forward...
6902 - drive side bearing and 2 more of those in the freehub,,,
Everything to measure power is within the hub, you do not disturb it...
