Can I convert a 1996 dually rear end to single wheel by just changing the outer hubs or do I have to do other things, Help

 

The dually pickup axle is longer than the SRW axle. (assuming it's a pickup rather than a cab & chassis) To get the correct tracking width, you'd need to change axles.
Standard pickup SRW axles are cheap, and lots of people want the pickup DRW axles for conversions...

 

Thanks for the information I guest I have to start looking for a single axle or convert my F-250 into a Dually.

 

Is your truck a Cab-n-chassis, or is a dually pickup? 2 different axles

 

Let me start from the beginning, I have a 1995 F-250 5.8L and installing a 7.5L miked/balanced. Have to up grade my ZF transmission which I have. A friend got me a 1996 F-350 w/7.5L but I am going to just use the ZF trans, Drive line and the rear end is the dually I was talking about. I will be pulling a 9,000 ibs Travel Trailer.

 

but the question still remains.there are two f350's you see.just like there are two f250's.
f250 LD (kinda like a heavy half ton is all really) -pre 1992 (and oddly one more time in 1997) - not an f250 worth a dually convert.
f250 HD (f350 pickup platform)
f350 pickup (f250hd platform)
f350 cab n chassis (didn't come with a bed.you added it.narrower leaf springs and frame.)

is the donor dually a cab n chassis or a pickup.the axles are not the same.only the dually pickup axle will bolt into your f250 and make it a dually.
you can tell via the vin or measure the frame.tip; the cab and chassis didn't come with pickup beds.if you see it's clearly sporting a dually pickup bed (and it lines up without looking funny) then it's "probably" a pickup.the vin tells all.

 

Your door tag if a C&C should say "INCOMPLETE VEHICLE MANUFACTURED BY" at the very top, atleast my 91 does. But about the easiest way to tell if that truck is a C&C is go measure the width of the leaf springs on the F350, if you get a 2 1/4" (2.25") measurement its a cab & chassis truck and you can't use the rear axle to put in your F250. If the springs are wider than that assuming your truck isn't a F250LD as mentioned above you're GTG.

 

there really is no reason to change the rear axle unless you are doing it to change gear ratio. both trucks will have the sterling 10.25 axle in them.

 

he is going from single to dual rear wheels. oops guess he is going the other way, my bad

 

he starts over in post #5 which clears everything up and makes the thread title correct.unlike how he worded things at first in post #1.
it's messy lol but i think he goes as follows:

95 f250HD with new engine and trans will be the keeper.a freshly put together 460/zf5 towing combo.
the 96 f350 dually is the donor truck,which sports the donor DRW axle for the f250hd axle & rim swap......at least he's hoping it is.

 

he wants to take a dually F-350 rear, and convert it to a single rear wheel.
and like i said, unless it is for a gear ratio change, it makes no sense. they are both sterling 10.25 differentials, so it will not be any stronger.

 

You still did NOT answer the question

Is the 96 F350 a DUALLY PICKUP or DUALLY CAB-N-CHASSIS?

The dually pickup axle is 6" wider than a SINGLE REAR WHEEL axle

The DUALLY cab-n-chasi axle is about 3" wider than the SRW axle AND the spring perches are in the wrong spot to bolt into a PICKUP

So AGAIN, what is the 96 F350

 

you could be right Tom.he didn't word things very easy for the best of support.but take another look in post #5:

"A friend got me a 1996 F-350 w/7.5L but I am going to just use the ZF trans, Drive line and the rear end is the dually I was talking about."

see how things changed?
of course he can come back to clear things up and hopefully and just start from scratch again.no sense trying to weed through a mess.

but,there actually would be a very very important reason why he would swap the axles if he's starting with a drw and wants to run the 96 drw as a srw truck.
lets say its a pickup;
reason one:
drw pickup bed $1000 -$1500 these sometimes sell for (i know,i know.crazy right? i didn't pay much more for a nice dump bed! lol)
reason two;
the drw pickup axle $500-1000 (i recently payed in between this myself for one,then had to buy all new brakes and drums)

drw rims;
easy $50 each x 6 = $300

so if a guy wanted to convert his drw pickup to a srw pickup.it could prove profitable to swap in the much cheaper srw pickup bed (or build a flat bed) and stick a srw sterling under it found about anywhere for $100-200.
take off the front hubs and sell those with the whole conversion kit too,and really make a nice hunk of change,while ending up with a basic srw truck.
in this case here,since he has an f250 which you think might be the donor (could be.i won't argue.he'll clarify if he comes back) he'll have everything needed minus some new u-bolts to swap over and the sale of drw parts = pure profit.


these dually convert threads don't have to get so complicated,but they almost always do.
