skeptical about a used rear.

Its going to depend on the d44 for stength. Nissan equips an 8.9 ring gear and 32 spline shaft model in their titan that is bigger and stronger than the 8.8" f150's have stock for stock. The shafts in the rubicons might be weaker but it won't be by much. They also have the 8.9" ring gear.

If Dana uses the same spline pressure angle on their 32-spline shafts as they do on all of their other axles (30°), i doubt they are stronger than a 31 spline 8.8" shaft which uses a 45° pressure angle (45° splines cut much less deep into the shaft's core for a given OD).

I'm not sure how any of this is really relevant anyway... the OP's axle isn't a 32-spline 2nd-gen D44 if it came from a '79-anything.

Nope but it has an arb in it making it simple enough to swap to a 1.5" 35 spline shaft and 8.9" ring gear. That makes it on of the stronger high clearance rears out there.

Hey guys sorry for the confusion the Dana 44 is for the front I just call them rears.

As for the axles I think right now I'll leave it alone being on a budget but later on that's deffinetly going to be an option I didn't even know you could have the arb built for 35 splines.

I still have not done anything with the rear I think I might get the 9 inch still deciding while I get a few bucks together for the swap . As for now I'm driving fine just no 4x4 since I have a 4.56 rear with 4.88 fronts

My great grandpa had a D44 in the rear of his '67 1100 IH pickup and it had a fondness of snapping shafts. He put two in it and eventually picked up an entire rear axle to have on hand for parts (which of course he never needed)

Ford did use the D44 in the rear of trucks, I think it was limited to the F-100 though.

I wouldn't stand in line too long for a rear D44, for being much stronger Nissan struggled to keep them together on the earlier Titans and I am sure they were stronger than the D44's of old as well.

That is very, very odd terminology. I suppose you say it goes on top of the truck rather than under it as well?

Then what do you call it? Axle ? It has axles in it.

No it has axle shafts inside of it.

As for the nissans blowing d44's I still don't trust one behind a reasonable v8 there is a reason ford only put the 8.8 in the v6 and 4.6l trucks I bet the 5.4l would smoke them.
