I have replaced the bearings on a few Reeflo's. It's not too bad to do yourself if you are a little bit handy.
Otherwise you can send it in to Reeflo for service, but the drawback is the shipping time both ways. The other alternative or see if there is a pump place locally that can help out. Baldor is a fairly big name for pump motors, so it should be possible to find someone who can work with them.

This shows the process for replacing the bearings (as well as the seals). The only thing is this example is showing the AOSmith motor, which uses different bearings than the Baldor (also the Baldor doesn't require un-notching the casing to get at the bearings, with the Baldors you just undo the bolts).

I don't remember the bearing part# for the Baldors. I'll see if I have that info at home and post back if I do.
