Shorten D44 Flat Top?

As some of you know I scored a D44 flat top out of a 79 Cherokee that I am building up for my 84 CJ.

This D44 is 4" wider than my D30. I shorten the D44 or leave it as is and let my wheels stick out 2" more on each side?


BTW....I'm running the AMC20 in the back...welded tubes...1 piece axles...ARB locker...I don't see any need to replace it any time soon...but I will have a D30 for sale in the near future...4.10 gears, Detroit Tru-Trac, all new u-joints, new calipers and rotors and set up for SOA.

AKA DDawg16

You have to check fit and measurements carefully. I put a '79 Cherokee 44 under my narrow-track CJ, SUA. To fit like stock I had to take 7" off the long side and 3" off the short side. That put the differential back close to its stock location.

If you don't narrow your long side I think you'll wind up with more sticking out on the left. Or you can outboard the spring mounts and move the diff a little farther to the right. Or if it's going to be SOA, maybe you can put the spring perch part way up the side of the differential, but that would cause added lift.

EVERYTHING's easy for the guy who doesn't have to do it.

Well if it was me I would keep it. You could allways get some spacers for the read 20. Plus you will have even better steering. ** Tire not so close to the springs **. It would cost you say $100 or so for a spacer and your done...
Less you like the Mod stuff then hack away..

I left mine stock and moved the springs.
My thoughts on this were:
Wider axles = more stability in off camber situations
Springs are easier to move than narrowing the axle
Allowed me to move the axle forward for a little longer wheel base
Don't have to order custom shafts when I break one

Then again I was swapping out the rear axle at the same time so I didn't have to worry about matching the width of the stock rear end.

It's all a matter of personal preference but I like the way mine turned out.

I agree with Mach. That's what I did when I swapped in my '79 F-250 Dana 44. Kept it full width and slapped some wheel spacers on my rear Ford 8.8, called it done.
Good luck,

You could allways find another AMC 20 out of the rear of a waggy and swap your ARB over if the splines match up. Im sure the splines wouldn't match up because nothing ever seems to be that easy..... Just a thouth, you might look into...

I'd leave it "full width" and either not worry about the rear or put spacers on each side. For what it is worth, I went to 60" wide axles on my 84 and was very pleased. I am now in the process of 64"/63" (f/r) axles.

Go full with or keep the 30, That 30 isin't a bad unit, Just not as good as a 60,,,,,

Leave it fw.

A few thoughts.

1. Definitely measure your jeep and the new axle, before making a decision. There are many widths listed on the internet for axles and they very a lot. Also remove the wheels to measure. I was amazed at the difference I got between Eyeballing the end of the axle with the wheels on and removing them an using a straight edge, about 2 " difference.

2. Every front Dana 44 Axle i have seen has a necked down area after the splines. The axle is not big enough to respline till 3" from the end. So your choses will be don't cut or cut 3+" off.

3. By shortening the long side more then the short side you may get out of running out board springs. However, this may lead to drive shaft clearance issues.


I will start using Metric only when the duodecimal system is adopted!!

keep it full width.. i ran a set of axles that width.. and thought it was about right for a jeep.. you will have to outboard the springs on a cj frame.. to get the axle to fit right.. then get a waggy amc20 for the rear.. so you can swap your locker and gears into it...
