    yeah...its really easy. It comes down to the "FF" and "SF" part of the name. FF has hubs that stick out like your front hubs do. There are 8 bolts I believe on the outsdie of the hub. SF will not have hubs that stick out. They will just be flat with lug nuts sticking out. Best that I can describe it /forums/images/graemlins/crazy.gif

    Sure, it's easy.

    You can find all the information you need at CK5 Axle guide page in the Technical section.

    TruckR4Me already described what the differences in the hubs are and that is the simplest identifying feature to look at, but sometimes you can't see the hubs and you need to look at the differential housing.

    The Semi-Floating 14 bolt axle has a nice round differential cover:

    and the Full-Floating axle has a very distinctive wedge shape:

    Hope that helps!
