    I just went off-roading this weekend and was doing a lot of water crossings. I took my hubs apart to do my brakes and had all kinds of water come out of there. I've been driving the truck everyday since I went off-roading so I would have thought that the water would evaporate. How do I keep the water out? It can't be good for the bearings.
    Any suggestions?

    Try replacing the little o-rings on the cover bolts and use Marine grease on the bearings as a extra precaution

    Another thing, make sure your wheel bearing seals are good. And there is a little rubber seal where the axle comes into the spindle, check and make sure that one is in good shape too.

    The water will not evaporate, it will mix with the greese and fianlly kill your wheel bearings, hubs, and then that ususally causes spindle damage at the least.

    Take both front wheels off and the rotors and clean them out and clean and re grease your wheel bearings, put in new grease seals (and bearings if they are bad) then replace the orings on your locking hubs.

    Any time you do water crossings that are deeper than your hubs you need to check and re grease the front wheel bearings when you get dont with your trail ride and get home.

    I had the same problem, forgot to check the bearings after numerous water crossings on a trip and the right front wheel ended up locking up at 60 mph on the hiway. Now i'm parting my truck out.

    I think maybe duct tape might work, too.

    Heres a pre-trail run tip...

    Use clear silicone from hardware store. Lock in your hubs, then silicone the area around the hub and hub case. Next smear some silicone over the hub to rotor surface. After wheeling, you can easily remove the silicone... Always check the hubs after deep water crossings over the hubs.

    You know, I've seen those little rubber caps somewhere before. Junkyard supply? If we could figure out another *common* source, I'll bet a pair with hose clamps would be well under $30...

    I have auto-locks on my 91. I took the cap off with the 6 screws holding it on. The "O" rings on the screw looked ok and the large rubber ring around the hub looked ok. To lazy to get some new ones. I put a bead of clear silicone around the hub rubber ring and some on the screws also. I'll find out if it works next time I'm in the water.
