    ummm, I'm confused /forums/images/graemlins/confused.gif, how is it that you have diff fluid leaking out of your front hubs? As I understand it, the hubs are independant from the rest of the axle. Is it leaking around the knuckles where the axle shaft u-joint is? You should see leakage there if diff fluid is leaking. Unless you are running a closed knuckle axle or something different than stock.

    I dont know. But now that you mention it, the hubs should be independent of the axle.. *scratches head*
    Guess I shoulda used a finger and smelled it. /forums/images/graemlins/rotfl.gif

    Assuming that you have internal style locking hubs, remove the outer section of the locking hub and see if the C-clip is still installed on the end of the axle shaft. If that's broken or missing, it will let the hub body move slightly outwards. Then wheel bearing grease can leak out between the locking hub and the wheel hub. There should also be an O-ring on the locking hub where it fits into the wheel hub. If that O-ring is damaged, it can cause leaks also. Look carefully for any water in the wheel bearing grease while you have it apart. If you find any, you'll need to clean out and repack the hubs. Leaving water in there for very long will result in etched bearings and races, which will then fail. /forums/images/graemlins/mad.gif
