2wd trucks are coil spring fronts.

4wd are leaf. Because the front leaf attachment point to the frame is also the pivoting shackle, the front of the frame is boxed. Whereas the 2wd is not boxed, only solid on 3 sides. This is true be they a F250 with the independent TTB or F350 with the solid D60.

This is the front frame horn of a 4x4 frame…compare how it looks to yours.

 

Yes all 2wd F150, F250, F350 were coil springs and TIB with NO STRAIGHT axles

 

TIB, what is that? Can it also be refered to wish-bone front end?

TIB= Twin I-Beam Ford terminology for the 2wd truck front end


No, I would not refer to it as a wish-bone front end.

 

I wouldn't either, but I think some people do. Twin I Beam is what it has always been called until on-line forums made typing it too hard, so it got abbreviated to TIB.

 

TIB = Twin I Beam(what has been on for 2wd trucks since 1965

TTB = Twin Traction Beam(used on the 4wd trucks from 80-97) excluding 85.5-97 F350s and 97 F150

 

You could use '05-up Super Duty axles to convert the 2wd to 4wd. Coil spring front suspension, so there's no need to worry about leaf spring mounts for the front.

 

Thank ya'll for thr info on TIB.

That would be easiest swap then? And as far as converting between transfer case and differential, can the drive shafts be used from the donor, or would i have to order some?

Thanks Boomer

 

Into a 2wd, I think it would be fairly easy. You may be able to re-use driveshafts, though I think the Super Duty uses a larger u-joint. There are conversion u-joints though, one cross will fit the OBS driveshaft, the other cross fits the larger Super Duty diff.

I'm unsure if Super Duty driveshafts will fit onto the splines of an OBS transfer case.

I'm actually gearing up to swap a set of these into my 95 F150 4x4, so I'm not 100% positive on driveshaft lengths and fitment just yet.

Super Duty axles are dirt cheap, compared to their OBS counterparts. I paid $800 for front and rear axles, coil spring buckets, radius arm brackets, all steering components, steering box, and track bar. They came out of an 06 with 60k-ish miles on it.

Installation is fairly easy, there's quite a few swap threads to be found doing a google search for "obs super duty axle swap".

 

Just an update, this is not a dead thread. Im just going to have to put it on hold, seeing as my wife and i lost our job.

Thank ya'll for your patience,

Boomer

 

Well, that sucks. Hope it all works out soon!

 

Here's a set of OBS axles with 4.10 ratio, in New York for $750. Freight might be a little expensive...

Thank ya'll, found a job waiting on back ground check.

Back to questions,

Were there any AT ALL 4wd dually obs trucks, stock that is.

Thanks,
Boomer

 

F-350 cab and chassis

 

Cab-n-chassis ONLY. NO 4WD dually PICKUPS were made from the factory until 1999
