    Bearing Seized!

    Has anyone else had the bearing, part number 5120 which is a 12x18x4mm bearing seize up? Was tearing down my slash last night to do some cleaning after taking on water and noticed the bearing wasn't spinning.

    I had two bearings seize completely and was barely able to revive two others, after running through a lot of water (and washing the truck with a hose), then drying it very thoroughly with a heat gun, and re-oiling everything. The stock bearings are very rust-prone. If you get them wet, you need to remove their seals, blast them with cleaning fluid, dry them, and *then* re-oil them. Kinda tedious, and tends to defeat the whole "waterproof" idea. I've swapped out all wheel bearings for stainless steel ones, so I hope that helps. I'll probably pack thick grease around the diff outputs the next time I run in the wet, but the bearings around the slipper remain very vulnerable.
