Hmm... water got in there somehow. I'd figure out what's going on with that before it gets put back together. It's worthwhile to install a grease fitting in the carrier too. I did that with my warrior, and pumped the whole carrier full of heavy duty industrial lithium grease. There is actually constant pressure inside it from the grease, so it guarantees that water will never work it's way in, and the bearings will constantly be lubricated good. Maybe overkill, but that was the 2nd time I had to replace the bearings, so I made damn sure I won't have to do it again for quite a while.
