The squeak is what prompted me to take it apart.
Once i removed the retaining nuts and washers on one side, the axle slid out. The non-drive side bearing popped out with relative ease. The drive-side is wedged in there pretty damn tight though. I tried several approaches trying to remove it, but gave up.
Some cartridge bearings have removable seals, you could clean out the bearings and grease them up again. The IRO ones im not too sure about.
