IFS diff swap idea....

[u2slow]

From the moment I saw JBA's steel diff replacement, I did some hard looking at some F250 twin-traction-beam scrap I have in the yard. It gave me an idea.

What if I could recycle one of these chunks and build an ifs diff assembly like JBA does? The high pinion alone should correct the CV angles for 2-3" of lift.

The chunk I have is a Dana 50 (F250HD), but there is a D44 (F150/F250) and D35 (Ranger/Explorer) variant as well. The 44 & 50 are 30 spline, and the 35 is supposed to be 27-spline.

Any comments?

Get a D30a housing and reverse engineer.

But is there room in the original mounting location for a D44 or D50?

Just looking,yes particularly if you drop housing 2-3 inches(bunch of mm). IF was going to use a D50,would put it in 44 housing,save some room.

The 44 and 50 are supposed to basically the same housing - just an extra inch of pinion snout. Still - it does look large. A 35 might be more realistic to start with. I wonder if it's worth picking up some scrap Explorer parts and tinker a bit

If you go with the D44, the grand cherokee CV, shafts and intermediate shaft should do the trick and be the correct length. The rest of the work is making the brackets and cut and fit axle tubes.
