man ill have to look into that. i never realized you could even take the little roller bearings out of that housing that connects to the pulley. Do you just tap them out or what?

In some instance, it can be easy. I replaced the one on my Yokomo chassis with no issues.
I wouldn't say you tap them out, but you can grab a plier and grab outer part of the bearing sticking out of the housing and pull the bearing out.
Measure the outer size, then measure the outer size of the cup's shaft part ( that's to get your bearing inner diameter, since you can't really get accurate measurement out of the inside of the bearing) and then get the length of the bearing. Then you should be fine to order.
Also, my assumption is that it will be cheaper to get the bearing than replacing the complete FOW, but in some cases, the complete FOW is so cheap that it's not even worth getting the bearings and you're better off buying a new one.
On the other hand, the FOW is cheap because it is made in china, so putting some good SKF bearings instead of crappy chinese one is basically like upgrading your FOW.
When putting the new bearings make sure to put bearing oil in the cage
