    No. The newer axles are wider, which is why they use a deeper offset wheel.

    The bearing hubs are different between the old and new.

    If you sat an old and new bearing hub (without the rotors) on a flat surface, such as a table, you will see that they are the exact same height.

    But when you look at the surface of the WMS, you will see the newer one protrudes farther out than the older one.

    Batmanjr has/had a pic of the newer bearing hub. He had sent me a PM asking why his rear disc brake brackets would not fit and we got to PM'ing back and forth with measurements and found out the bearing hubs he had were the newer style.

    While this is true on 6-lug 4x4's... I haven't found this to be true on the 8-lug trucks - the wheel offset is comparable to the 87-older trucks. However, the overall width is still different since the shafts will not interchange.

    The bearing hubs are different between the old and new.


    Do you mean the "pull-off drum" style or the "conventional" style (drums mounts on back of hub)? The hubs with the pull-off drums are different for sure - but the other hubs? Looks to me like the only difference is metric vs. SAE studs.
