Conversation about putting a Late 70's Dana 44 into a JKU

Thinking of the possibility of putting a late 70s high pinion dana 44 into a JK
Reasons would be to loose the unit bearing, a better high steer setup. Stronger c's, tubes and ball joints.
The only real issue I can think of is no abs. Could this be added?

What are your thoughts and does anyone know if this has been done by anyone?

Thanks
Tony

They are hardly an upgrade from a JK 30, and certainly a downgrade from a rubi 44.. You’ll also need to clean the axle of the cast mounts, position/weld all new brackets on, rebuild/regear a 40 year old axle. You will have just as much money as swapping a Dana 60, without nearly 1/4 the benefit.

An f250 dana 44 has leaf spring mounts that can easily cut off. I also don't see how it's not much better from a dana 30 also a rubi 44 has thin axle tubes and uses everything a dana 30 does minus the center section. I'm not running high horse power so I don't see the need for 1 tons.

Good point Nucleophile. I forgot about the cast spring mount on the drivers side and thought the ring gear was the same size.
Ok now for the outer knucle and c's, could the be put on the outer tubes on a rubicon dana 44. Might need to machine some custom tubes but this would give me manual hubs, better ball joint, the ability to mount high steer arms on the knucle and also loose the unit bearings. Also allow me to put thicker tubes and add more caster during the build. Biggest issue I see would be figuring out a tone ring for the abs.

There are a few options to add locking hubs to a JK. The first is a Teraflex kit that is bad ass, but converts you to 8x6.5. Another is Spyntec that converts you to 5x5.5. A 3rd is a kit by The Ram Man that lets you keep your 5x5 bolt pattern. I know that none of them are cheap and don’t do anything about the lack of highsteer arms. But they are all locking hubs that have ABS for a JK.
