Loc-tite 680 is some very strong retaining compound. I've used it before at work, on bearings that are just a little to loose of a fit on shafts tightly, and trying to remove an old bearing with this stuff on is very difficult. You have to use some heat, or else you'll destroy the bearing in the process of pressing it off. 680 might be worth a shot. Just keep it out of the bearings themselves, and do a good job cleaning off the oil from the shaft and mating parts.

290 is another great product. It definitely wicks into anything! It will work as a retaining compound too, but not nearly as well as 680.
