i did the d44 swap.. ive noticed my rear sticks up a little higher than usual.. a guy in my jeep club said because the control arm brackets stick up higher on the d44 compaired to the d35.. not sure if this is true or not.. but i went from having about 1.5'' difference in the front and rear to about 2.5''
its all good though.. all i have to do is swap out the 2'' coils i have for my stock ones and if it sags more than the front i can adjust my acos =D
you gotta make sure you have the right gear ratio.. i thought my jeep had 3.73s because i didnt have any issues of it becoming slower with 33s.. i got the d44 with 3.73s (either 3.73s or 4.10s) i ended up having to regear a d30.. i took the time to upgrade to the hp30 when i had to regear it

JK Dana 44 axles are not a bolt-in for a TJ, their brackets are set up differently so they would need to be moved (cut off and rewelded) so it could be installed into a TJ. So far as I can recall, only the lower control arm brackets can remain in place as is.

do the 8.8 or the dana44
the dana44 from a tj is a direct bolt on swap but it shares the same axle tube thickness as the d35
the older dana44's have thicker axle tubes making them a little beefier then the tj d44 but you will have to weld the brackets on
the 8.8 is a little stronger then the d44 with the bigger ring gear and 31 spline shafts
with the d44 you can put 35 spline shafts in the rear and a disk brake swap
either way you go the 8.8 and the d44 and the 9" are all good swaps
with the 9" rear you can easily build it to run 40's
the jk axles are an OK swap
but I know a few people running the rubicon and has had problems with the axles and they are bone stock
one of them has had the rear axle replaced twice and the front once
the other guy has replaced the front 3 times
all in the past year
I also know a few people running the jk rubicon with 35's and they havent had a problem yet and they wheel it pretty hard
