    I just bougt my new parts rig. A '79 3/4 ton....How come the hubs on the 14 bolt only come out 2 inches or so? The other 3 14bolt axles I own all come out about 4 inches. Whats going on? I dint really want to crawl around in the mud too much so I never looked at the front axle. Should be a 10 bolt for this year right?

    I'm not too sure on the answer to your question, but I do know that there are 2 different styles of the 14B FF.

    One has the Hub built onto the drum itself, and the other has the drum seperated from the hub.

    Tom the ones I just bought look to be the same as what you have on your rig

    I have not heard of this difference between hub designs. Can anyone elaborate?

    Luke,

    If they're the same as mine, then they should have the bearings inside the drum. If all 3 of your axles are like this, are you sure the difference you are seeing isn't rim depth? or backspacing?

    BTW: would you happen to have an extra hub for the 14B FF? I still cannot get my axle seal to stop leaking and it's gonna take a replacement hub to fix it.

    Mike,

    The design I have (bearings and hub integrated into the drum) requires you to remove the axle shaft to get the drum off.
    The other design has the drum seperate fropm everything else, like most axle setups.

    Tom I dont think I have any extra hubs, I'll have to look around. All of the ones I have owned I believe you have to pull the axle to get the brakes off (hub is attached to the drum) Here are pics I hope they show what I'm talking about. The axle is a 3/4 ton....the one with a dished (also figure there is 2 rims and a ring in there)wheel 1 ton...both 14 bolts.

    Yea, that looks just like mine does; The hub will seperate from the drum if you beat out the lugs with a BFH.

    So what does the other one look like? Does the hub stick out more or less? Also, is it a dualy? Maybe the 1 Ton has a different spacing or something?

    Sorry i couldn't be of more help, good luck

    Thomas.
