what years did ford use that IFS crap?

[robselina]

From what I'm gathering from the D60 FAQ, it looks like from 1980-1985, both the F250 and F350 had that funky IFS. Is this the case or did they use D44s during this period or something? Looking for a donor vehicle for axles to my Wagoneer project.
Thanks,
Rob

I think Ford used the dana 50 ifs in 1980. I am not sure about the other years.

'80-'85 F350s and all '80-'97 F250 have the leafspring TTB axle
They are Dana44s or Dana50s. I'm not sure the years it switched over to the 50. I know a '88 F-250 with a 351 is a D44.
F-350s got the D50 sooner than the 250.

If you're lookin for a D60, skip these years.

The F-350 is a straight axle/leaf sprung as far as I know in all years.

Ford introduced the TTB in 1980 in the
F-150 with a D-44 (coils)
F-250 with D-50 (leaf sprung)
According to some, the D-50 and D-44 third member where interchangeable. (I never verified this)

When ordering parts for these front, you have to specify that it is a TTB model because the parts (lockers) are not interchangeable with straight axle models.

Early model rangers had a D-28 TTB set up (breaks axles like glass)
It was later upgraded to the D-30 (I think).
The 4.0 models and explorer came with D-35 (I think in the later years.

In 1997 they swithed to the current IFS front in the F-150 and light F-250. I don't know anything about the newer body F-250HD and F-350.

Rangers never came with d30s, although some did come with 35's, Im not sure what years or configurations except that all 4.0 rangers came with TTB 35s except 98+ which are SLA D35s for all models.

I assume all you care about is F-350's
Pre 1980 they were all solid axles
1980-85 ALL TTB (ford;s IFS)
86 was mix and match with let over parts, some were TTB other Solid axles

cool. I'll stay the hell away from those years. I would like a D60 if I can find a donor that won't break the bank, I'm keeping my eyes peeled.
Thanks guys,
Rob

Roar Johannesen is racing a D50 IFS with great success. And he pounds it with well over 800 hp. Check it out!

This is also incorrect.
There is nothing different inside the diff of a TTB D44 vs. a straight D44 outside of a circlip on the end of the right axleshaft to retain it in the housing. If a particular diff won't allow reinstallation of that clip (ARB for example), you use a stiff spring in the slip-shaft to keep it in there.

The D50 ARB was designed long before the SA D50s came about, also.
