ZJ Dana 44

The ZJ Dana 44 is the only Jeep Dana 44 with an aluminum differential housing. It is also a C-clip axle with one piece shafts and a 5 on 4.5" wheel bolt pattern. Because of the aluminum housing and C-clips, it is not really any more desirable than a Dana 35c. The shafts are 30 spline.

Specs

The Dana 35c is the axle used in all YJs (Wrangler) from '87-'95 and it is the standard axle in the TJ (Wrangler), ZJ (Grand Cherokee), MJ (Comanche), and XJ (Cherokee). The Dana 44 is an optional axle on the TJ, ZJ, MJ, and XJ. Some XJs were built with the corporate Chrysler 8.25 axle as standard. The TJ and ZJ versions are coil sprung, the XJ version is leaf sprung (spring over), and the YJ and MJ versions are leaf sprung (spring under).

ZJ '93+

Got a pic?

sorry for the double post, but...
The aluminum D44 was an option in the ZJ from '99 on, I cant find anything online about a D44 in ZJ's older than that.
Correct me if I'm wrong, 'Cause i might be.

Mark: Do you happen to know the weight savings?

well dont I feel stupid,
Turns out that my buddies D44 is MOSTLY out of a '94 limited, the center housing was custom replaced with a cast iron one.
Sorry for any confusion I caused.

wouldn't '99 on make it a wj?

I agree on the Ford 8.8....its much stronger....the aluminum case on the ZJ D44 will not take ANY trail abuse for long....the case will crack, as well as the cover peeling (this I saw being hauled out of the Roosevelt Natl Forest the hardway)

i know the 8.8 is stronger than a 44, but is it really that much stronger? i like to see the numbers. the 44 is used in vipers with 450 (minimum, in '92) ft-lbs of torque, and more traction than god. i'm sure there are differences between the two, but i think the 44 is a pretty stout design. with a skidplate it think the disadvantages are reduced a lot. now there just needs to be some good diffs. my guess is most people stay with the quadra drive "varilock" differentials if they've got them.

i know that article in four wheeler mag that gave #rs for different axle strengths shows the 8.8 is stronger by a couple hundo ft-lb. i cant remember the exact #rs. BTW that article is really good. shows comparisons of axle size to strength. increased leverage due to increased tire size. and torque capacities of high strength alloy axles for all diameters compared to stock materials. take a look next time you have a chance. could be a great reference.
