JK Rubi D44 fronts aren't really D44s.

 

And you'll pay out the *** for them. Sell for like 3-4 grand by me.....screw that.

 

Those yota axles are fairly similar to the 9" in construction.

 

If your planning on fullwidthing It would be a great axle you wouldn't have to worry about breaking. What year axle is it and what did it come out of ? On the superdutys the lug pattern was 8x6.5 then they changed them to 8x170mm so that's something to look at if your not wanting different lug pattern per axle. To fullwidth the front you want a yearly ford dana 44 or just about any ford dana 60 but your talking some cash there.The Chevy axles are pass side drop and you would have to swap transfer case to make that work so it would be tons more work. Newer Dodge front axles would work but they have a unit bearing like your Cherokee has now which would work but If I was doing it I would want selectable hubs.

 

If you don't want to swap the front you could always do the ford 8.8 31 spline swap they are dirt cheap and there is little fab to install them. Oh and you get disk brakes to if you grab the correct year.

Dont the 8.8's use a c clip to hold the axle in?

 

Yes, but i'd say it's the swap that makes the most sense if you wanna keep your jeep as close to stock track width, but adding a ton of strength. plus discs. It's a smart choice.

 

Yup and there is a super 88 kit that adds better axle shafts gets rid of the clips and moves to 9" big bearings

Is a sterling 10.25 larger than a corp. 14 bolt? And would the 14 bolt be a better swap into my jeep? Full float corp. 14 bolt from a 1990 3/4 ton suburban.

 

Roughly the same for offroading I like the sterling better since its got better clearance

They make a real nice shave kit for the 14FF.

 

and there is a much simpler one for the 10.25.....

 

Well I didnt know much about the Sterling 10.25 until I just did some research.

Now I have to ask the OP if the axle is a full float or a semi-float..

I also have to ask what is the final gear ratio you plan on running?
According to the book I have (5 yrs old now) the deepest ratio is 4.30


Now for some tech talk

Axle shaft

10.25 14ff
1.5/35 splines 1.5/30
minimum shaft
1.36 1.34


SO if bolt pattern and gear ratio choice is not an issue the 10.25FF is just as strong/ shafts stronger , ring gear weaker then a 14FF


The strength of the 14b comes from the fact thatr both ends of the pinon are supported. ALso you can go to 5.13's in gear ratio.

 

The 14bff can be had with 5.38s

 

LIke I said my book is 5-6 yrs old... things do change some

I am sure the sterlings have more gear choices now... too butnot 100% on that.
