Hey, I'm new to the forum but I have also had problem with the egg beaters. I blew through 2 pairs in about 6 months when they first came out. I was a bike messenger. Bearings went on both pairs, almost completely discintegrated. I thought I was lucky that I had bought bearing "repair kits" ahead of time. All I had to do was get the old bearing pieces out and replace them with the new ones. MUCH easier said than done. to this day, I still haven't been able to get the old bearing inner sleeve off of the spindle from one pair or the outer sleeve out of the pedal body from the other. They are rusted, or cold forged, or whatever you want to call it; into their respective locations.
Luckily i had bought 3 pairs of pedals (so I didn't have to swap them from bike to bike to bike) and I still have the 3rd pair to ride, and love them. But I still haven't been able to get the old pieces out of the other pedals. When the 3rd pair goes I'm sending it all back to their maker for a possible replacement. So you might want to try a similar tactic because you probably won't be able to get your pieces out either, (although I did not have the stainless version so you might have better luck.)
Their recommended method with the instruction kit was to put an allen wrench (I forget which size) into the pedal body, and use hammer to pound out the old bearing. It will have to be big enought to not go through the bearing, but to "grab" the bearing.
But my pedal body had a recess which "hid" the piece stuck inside of it, since it wasn't a whole bearing anymore. And they didn't even have a method for removing the piece stuck to the spindle. Many bloodied knuckles from the hammer and screwdriver method have made me give up.
But I still love their ease of use, and I'd probably buy them again.

Good luck
