i just now got to the thread, i didn't realize you had a jk. i'm not 100% on that, when it comes to jeeps i get fuzzier as things get newer. i can't tell from the front of the picture either, from the side i could tell better. i know they changed things on the jk, not sure on those gears.
d30 yes, and is either d44 a rubicon axle? rubicon gears are thick cut gears, and tj d44 are not, tj d44 are the same gears as all the d44's in the millions of years past, but rubicons had to go be different, and are thick cut. i know you can run rubi thick cut 4.10's in an older d44 by using the smaller carrier, but i don't know if there's a way to go the other way. but if they're both regular tj d44 axles then yes they will work.
would you mind telling me if the 410 gears out of my Sahara d30 & d44 will go into a 2004 with d30 front and d44 rear ? thanks, a member wants to know as I am selling them & don't have a clue!
