dana 60 rear?? i dunno is your front ttb suspension?

11-13-2006, 08:11 PM
yea i think its a dana 60 and i got a pic of the front.


11-13-2006, 08:12 PM
Your front end is probably a Dana 50 TTB if it's independant suspension. Mabye a '60 because it's solid?

Your rear might be a Sterling 10.75, Or mabye a Dana. Check for markings on the axle itself.

11-13-2006, 08:16 PM
the front doesnt look like independant suspension though.. its leaf springs??

11-13-2006, 08:26 PM
hmmm i think its a ifs

11-13-2006, 08:29 PM
its ford twin i beam suspension, aka twin traction beam (TTB). More than likely dana 50 ttb front and sterling 10.25 rear. Im guessing.

11-13-2006, 08:31 PM
It is ether a a ttb dana 44 or a ttb dana50 if the rear is semi floating you will have the dana 44 if it is full floating you will have the dana 50 the rear will be the typical ford 10.25 semi floating or full floating

11-13-2006, 08:36 PM
d50ttb and a sterling in the rear there are 3 different ones

11-13-2006, 10:11 PM
If the front hub tapers down to the lockout then its a (heavy duty) ttb 44 being its a 3/4 ton. If its a bigger lockout like a 60 then its a ttb 50. Rear could be a dana or a sterling. Most likely is a sterling

11-13-2006, 10:45 PM
250s always have D50TTBs, to the best of my knowlage.

11-13-2006, 10:56 PM
thats a D44 HD. The D50 has monster D60 sized hubs, that is definately a D44 you have. Your rear axle is a sterling 10.25" (ring gear size), if you can pull the axle without removing the tire and drum (there is a rear 'hub'') its the full floating set up. If you have to pull the tire and drum (the axle sits flush with the drum) its a semi-floating set up.
Full floating carries no weight on the axle shafts.
The TTB D44 HD is not much better than the F150 TTB D44. The rear diff is bigger than a D60 (9 3/4" ring gear). The sterling is a good axle either way.

Is there any weight on that spring in the pic?

11-14-2006, 02:18 PM
umm here ill go take some picks right now

11-14-2006, 03:18 PM
ok here are some of the front and rear



11-14-2006, 03:25 PM
thats definetly a sterling 10-1/4 rear take a pick of the end of the shaft at the wheel and we can tell ya if its full or semi float

11-14-2006, 03:29 PM

11-14-2006, 03:30 PM
dont kno what the front is

11-14-2006, 03:31 PM
semi floating sterling 10-1/4 and the front loks like a 50 to me hard to tell from the picks tho

11-14-2006, 03:35 PM
semi floaing what does that mean, and im asumeing these will be able to handle 33 or 35s

11-14-2006, 03:42 PM
youll be fine up to a 36 for that front and a 38 for the rear a full floating dif has a spindle and bering assembly so that the vehicles weight is suported buy the housing not the axle the axle merly turns the wheel

a semi floting axle the axle shaft bolth suports the weight of the truck as wel as turns the wheels

11-14-2006, 03:47 PM
hmm thanks for all the info, yea my truck is stock height and i dont know if ill be able to fit 35s under it

11-14-2006, 04:00 PM
just keep cutting

11-14-2006, 04:41 PM
3 inch body lift u should be able to fit 35's no problem.

11-14-2006, 06:35 PM
full float carries no weight on the axle...semi-float the axle carrys some weight.
Thats a 44HD, not a 50.

heres a 91 F250 5.0L with 3" body lift and 35"x12.5" procomp x-terrains, my cousins truck.

11-14-2006, 09:13 PM
you could run 44s with the sterling. Its damn near bullet proof but i recomend welding the pumpkin to the tubes.

11-15-2006, 01:12 AM
yea i dont think ill be able to run 35s with stock height

11-15-2006, 08:10 AM
yes, but you'll have to sawzall the shit outta the fenders.

Nile, When i get a new motor in my rig, you wanna go wheeling?

the front is a ttb 50 i have seen this truck in person.....[cheers]

ya find some 33" tires go from there then as u bash body panels u can trim and eventually upgrade [cheers]

11-15-2006, 10:26 AM

Thats a 44 not a 50. The sze of the hub says its all. Nothing HD about it either [22]

ah yes u are correct wise one

my bad it does neck down on the Hub.... either way i was drunkat the time and it was dark and i was dressed as a doctor......

11-15-2006, 01:20 PM
Thats a 44 not a 50. The sze of the hub says its all. Nothing HD about it either

I recall saying that....

thats a D44 HD. The D50 has monster D60 sized hubs, that is definately a D44 you have.
on page one

Thats a 44HD, not a 50.

...and page two again.

Ford didnt put the stronger of the two options up front (d50) with the weaker (semi-float) of the two options for the rear.

11-15-2006, 01:21 PM
Nile you got any shots of the whole truck?

11-15-2006, 09:33 PM
lol yea lots


11-15-2006, 10:39 PM
The ttb f250s are the easiest trucks to do a SFA conversion on...ever. All you need is the axle and a trac bar. You can even use rear leaf packs to lift the front, just gotta have em arched to 50" spring eye center-center give or take an inch (from 54"). I dont know about the pin location tho.

11-16-2006, 08:41 PM
so is the spring pearch spacing the same on a D60.....

11-16-2006, 11:48 PM
so is the spring pearch spacing the same on a D60.....

Yes, so long as its an 86+ Ford D60.
