minihune,
the wheel bearings are not sealed to 100% isolation. The things that happen to bearings and their grease that are submerged is that some grease is removed and some grit is deposited. Bearing grease sticks pretty good and is pretty good at preventing water from entering the bearing under normal use conditions. After I run my 4x4 through streams, rivers, and lakes for 2 days or so, I'll replace the bearing grease. The primary reasons are to insure there is enough grease; that it has not been affected so that it lubes and cools properly; and to remove grit. In my street cars that have been flooded, I repack the bearings with new grease. It is easy to do and is inexpensive. Relative to new autos, especially my MINI, the factory was pretty stingy with grease and oil. Every time I look at a hinge or take something apart, wheels included, there was never sufficent lube to begin with. Combine this with street cars that see higher and higher constant speeds than my 4x4 and you have a likely need to repack the wheel bearings in an auto that has been flooded.
Use a bearing packer. It looks like cymbals, one of which having a zerk fitting on it, and a grease gone to repack wheel bearings properly. These tools are cheap. The job is easy.

Have you done this on a Mini?
