    One front wheel spinning faster than the other.

    Maybe you guys can help me out here. I've got one front wheel spinning faster than the other. Ones will freely spin for over a minute and the other for maybe 20 seconds. I've replaced all front bearings and the hub carries have also been replaced. Tried switching the axles around too but it stated the same. What could it be?

    1. The bearings may not be broken in
    2. The hubs may be rubbing on the bearing.
    3. You may have tightened the wheel nut too much.

    My vote is on #3, especially if you're using rpm steering blocks.

    How do I break in bearings? and on #3 this is even without a wheel on. Just spinning the axle by itself.

    To Break in bearings, just run your truck.

    The nut only needs to be slightly tight.

    The hub has a little overgrowth to it which might rub on the bearing and cause excess drag. I used a dremel on mine.

    As stated above,if the hex pins is bent, the hex it self is wore from over tightening,or the axle shaft itself is bent ever so slightly.
    All of these can cause your issue.
    I changed to aluminum hex wheel mount's,and never had the problem again.
    And you break in the bearings by using it.

    It's maddening trying to figure that out. I've had the same problem over the years.

    It could be the bearing carrier is warped. What brand do you have?
