Danna 44 swap

Will a danna 44 from a 75 cj5 fit a 1981 cj5. Would the perchs be narrower? I have a chance to pick up a 75 cj5 and would only buy it if the rear end would work in my 81 cj5.

The spring perches are on the axle, unless someone removed them. You're going to need to get new unbolts and can use the spring plates from the axle you're pulling. Biggest concern is if the gear ratio matches your front axle

Cut and re-weld the spring perches on the rear. The front is a bolt in swap, and you damn swap your disc brake stuff over

Spring perch distance is different, so as said, remove them from their current position and move outward.

This is fairly easy to do and when I did mine I bought new perches. They were only about 25 bucks. Not worth trying to save old saves much time.

Flanged Dana 44 is mid-70 through '75 and then the mid-86 CJs had the Dana 44.

Pre-70 is a two-piece axleshaft, not flanged.
