XJ Dana 44 Swap

[carone]

I snagged a D44 from an XJ at a local pick and pull that I am going to swap into my Comanche. I was wondering how everyone was running the shock mounts and what u-bolt plates I can use (I forgot to grab the plates from the Cherokee). Are there any other issues that I need to worry about aside from relocating the spring perches and relocating the shock mounts?

make sure the brakes are there and working, and that the bleeders arent snapped off

I'm just using my d35 ubolt plates/shock mounts, they fit fine

Just so you are aware there are 4 different size wheel cylinders that will fit a XJ/MJ rear axle and they can be used to increase the rear braking power. Try it the way it is and upgrade later as needed.

 

This a great way to increase the braking power after a D44 front axle swap is done with it's larger brakes, or to match a WJ front brake upgrade.

Got specifics? I knew the D35 wheel cylinders were different from the D44 wheel cylinders, but that's only two.

Bendex# 33627 & 33628 = 7/8"

33004 & 33005 = 1"

33206 &33207 =1 1/8"

 

I believe there are at least 1 to 2 more sizes.

Getting ready to do this same swap myself and was wondering if anyone had any specs on the difference in U joints....driveshaft lengths.....spring perch specs/dimensions....etc.?

 

Mine's goin from an 87 xj 2 door automatic..(Dana 44)...into an 87 mj automatic longbed....(Dana 35).

 

I also have a tom woods shaft out of an 88 xj 4 door...5 speed rig and would like to use it if possible in my comanche build.

 

 

THANKS guys.....sorry to hijack but at least it's on topic!!!... :D

I am almost positive that unless you have a really long XJ you won't be able to use you TW shafts as it is... But most driveline shops will retube/lengthen it for less then a third of a new one

 

 

Also look for MJ jeff's build... we swapped a MJ d44 under his rig, but we went soa... pretty much the same thing. Just moving spring perches around
