A friend of mine has an '84 Bronco and just bought an '85 F250 for parts.

He's looking to swap the 8-lug 60 rear into the Bronco, and wants to convert the Bronco's TTB 5-lug '44 over to 8-lug, ideally using the F250 ends, not swapping the whole TTB front end.

Anyone tried this/know if it'll work?

Here's what he's trying to do:

Does anyone know offhand if I can take from the balljoints out on a 3/4ton
ttb system (85 F250 4x4) and put that on a Bronco (84 fullsize) without
changing out the housings and brackets? Both are D44 centers and the axle
joints are the same.
Thanks,
Blair

That's what he was thinking (and it makes sense to me).. but then someone came back with this article:

Nope, need to use chevy stuff. See

http://www.Off-Road.Com/ford/bigbroncos/tech/8lug/index.html

Which claims it "can't" be done.. then again, maybe the guy that wrote that just didn't think like the folks around here do. <IMG SRC="smilies/biggrin.gif" border="0">

actually (biteing my tounge) the TTB 3/4 ton stuff is a Dana 50 right? then i belive it will not bolt up, you would need to find a old Stright axle D44 parts,
as for using chevy stuff i have never heard of that

This donor is a '44 <IMG SRC="smilies/frown.gif" border="0"> He was hoping for a 50 (in which case a full swapout would be the way to go). No such luck tho'.

Still, the 460 was worth what he paid for the whole donor truck..

I found some info elsewhere about having to cut n' weld balljoints.. but we'll see.

I am sure you thought of this but are the gear ratios the same between the donor and the bronco? If not better swap the whole thing.

IIRC, The Bronco/F150 is coil sprung, and the F250/F350 is leaf sprung <IMG SRC="smilies/rolleyes.gif" border="0">

Might complicate any swapping....

Point to ponder: Why does a GIF file have to be bigger than a JPG <IMG SRC="smilies/confused.gif" border="0">

He just wants to use the knuckles out forn the F250....doesn't matter that it uses leaf spring.

And lots of 3/4 tons used the TTB HD44....they should bolt right on to the 1/2 ton TTB44

The solid axle 44 knuckles won't work. The TTB D44 knuckles are father apart from balljoint to balljoint than the solid D44 knuckles

Ahem, I belive that "guy who wrote that" would be me <IMG SRC="smilies/wink.gif" border="0"> I did try the F-250 TTB D44-HD parts first but it was a no-go. The ball joint spacing on the 44HD is further apart than on the regular 44, no way it'll be a bolt-up swap. I then looked into using 44HD spindles, no-go either, different bolt pattern. The chevy swap is pretty much a direct bolt-up swap, just have to cut off the caliper ears.

Oh, and here's the link to my write-up which Off-road.com used-


8 Lug Swap

a beter option would be swap in a solid front:D . or if you set on keeping the TTB cut the ends off the 44 and weld the ends of the 50 on. at this time you could cut and turn it like the baja guys do, 4" bracket cut and turned beams you could get 8" lift and keep the correct camber. i have never seen the mutt beams but it should work and you would be able to run the outer u-joint from the 50. i highly recomend swapping in the 50 center joint to any one who realy uses their truck, especialy if they run a locker. it will save you some down time on the trail, well at least untill the outers go;).
