Dana 44 or Ford 9 inch rear?

I have a Dana 44 out of an XJ that I was planning on putting in my YJ this winter. Yesterday I found a Ford 9" out of a '74 Bronco locally for $250.00. I currently run 31" tires and someday would like to go larger. Any thoughts to which axle would be best? I know the 9" is stronger but it would involve more work. The XJ would be much less work, but something about the 9" is very appealing. Any thoughts or shared experience would be appreciated!

The 9" will have a different bolt pattern than your YJ, and I'm pretty sure the EB axles are a few inches narrower.

Personally I wouldn't bother with the 9" since you already have the d44 that is as close to a bolt in swap as there is. With the 9" going for $250 in unknown condition, the need for new shafts or wheel spacer/adapters, and who knows what else it seems like a waste of money...

On the other hand, it's your money, not mine.

The 9inch will be better long term because of the aftermarket support for it. It is much stronger than a Dana 44A. that being said..

Bolt pattern
width
gear ratio
brakes
eventual tire size
front axle
project complexity
cost
brackets


all things to consider

the 9 inch is indestructible basically. D44 not so much... 250 is a good deal considering many d44's go for 3-4 times that much around here. but i guess that balances out with the work you're gonna have to put in.

I would keep and run the 44, easy and cheap to adapt it. If in the future you ever find it weak for the tires you choose to run you can sell it and go from there. It will take some effort to break it on 31s tho..!!! I think you will be safe up to 35"

If you're not going to go much bigger than a 31" tire I wouldn't bother with the 9". IIRC the 9" will eat up ground clearance, more so than the D44 with 31's.

Im also a Ford 9" fan but that 9" is most likely going to be a 28 spline unit. With 28 spline shafts the Dana 44 is going to be the stronger of the two. You can of course upgrade the axle shafts to 31 spline or better, but you will add several hundred dollars to your swap right there. The 44 sounds like your best deal right now.

that is what i was going to say that is probably a 28 spline 9" and not as strong as the 31 spline 9" and the 9" has a super low pinion which is not friendly to our short driveshafts. I would go with the xj D44

xj d44's are quite rare and valuable for some strange reason

I'd sell the d44 for an outrageous sum and build the 9"... well... to the nines, or do the same with an exploder 8.8 and have a stronger axle with all the goodies

The early bronco axles are getting real hard to find too, they are popular in the hot rod scene because the 58.5" width is perfect for a lot of cars. I sold a bare early bronco housing for $150 not long ago. Still got another im gonna clean up and sell.

got to love that 8.8 picked on up in a junkyard for $250 came with rotor, calipers, spring plates, u-bolts, e-brake and he gave me the drive shaft so i stripped the flange off of it.

I have a 60's f100 axle at that width I can't move for the life of me.

You have to paint it nice and put cool stickers on it, then it will sell
