    Is there any way of telling if an axle is a full floater vs a normal 14 Bolt? Any markings or anything that would distinguish one from another? I have found a 14 Bolt full floater for $200 and just want to make sure that it is an actual full floater.
    Thanks for the help guys,
    Andrew

    Full floaters have the hub in the middle.

    from the axle info:

    "The "small" GM 14-bolt has a 9 1/2-inch ring gear diameter. It was used in the rear of 1964-and-later GM pickups, and in the rear of 1984-91 3/4-ton Suburbans."

    I know this axle wasn't used in 67-72 trucks. The only 3/4 and 1 ton rearends were the dana 60 and the eaton ho52/72. i guess there was a sf dana 60 found in some BB 1/2 tons, but no 14 bolts.

    I beg to differ here...I used to have a 72 C20 years ago with a factory 14FF

    For every so-called "info" sheet there should be a "corrections sheet /forums/images/graemlins/rolleyes.gif. This rear axle didn't appear until '81 and is still in production.

    Should work... the 1-ton (and 3/4-ton longhorn) D60 have 40.5" spacing and both shocks inboard & angled forward.

    i think that the dana 60 was only found on some 67-72 3/4 ton trucks...the 1 tons all had eaton ho72's, and 3/4 tons had the ho52. most seem to have the eaton.

    oh boy...


    no 14 bolt FF til 73, everything before 73 had 10 bolt covers no matter if 60 or eaton


    ho52 and h073 were the 3/4 and 1 ton axles from 47 to 72, only difference between the two were brake size just like from 3/4 to 1 ton 14 bolt FF

    dana 60 were in alot of trucks 3/4 ton 72 and older, most all were leaf sprung

    67-72 2wd except longhorn and 1 ton were coil spring or 42.5" leaves

    4x4 and 1 ton and longhorns 72 and older were 40" centers

    any of the 42.5" axles will go under any trucks with 42.5" packs, but shocks moved to both sides of axle in 73
