Confused about which 14 bolt FF I have...

[crashandburn]

I am trying to figure out if I can do a disc brake conversion and I seem to have conflicting information about whether it is a new style or old style, so here goes...

It's a 96 Suburban, 6.5 TD.
So it should have the new style, but many rigs through the 90's still had the old style. So that doesn't help.

My drums DO NOT come off just by pulling. I yanked out the axle and the 6-hole nut that holds the drum/hub on, and the drum slid right off.

That sounds like old style.

BUT.....

My drums have the studs sticking directly out of them. They do not have the wheel mounting surface separate from them.

That sounds like the new style.
So that doesn't help either.
Anybody set me straight about this?

lots of the pop off drums are rusted to the hub .

is the drum on the back side of the hub with studs pressed threw them to hub ?

drum on back side of hub = old style.

studs pressed directly in hub then drum on front face of hub = new pop off style .

new pop off the every day dick kits wont fit . spindle bearing spacing is diffrent and cant swap on older hubs also . i figured this out years ago the hard way .

Damn, looks like its the new style.

The newer trucks all have disc brakes. Could I swap in a setup from one of those?

possible but check the flange position and clocking . i tryed to swap on disk from 10 bolt to 14sf same range of axle but flange was welded deeper and clocked diffrent on disk rear.

also try finding cheep / res priced disk axle parts in the yards for the newer stuff = BIG money most the time. if me i would just buy the whole axle and swap it in that way .

there is 1-2 places tho for disk kit for newer axle if you look. but i cant recall at this time who .
