I think the Rubicon has a D44 axle in the front and if yours is just a plane Jane JK it will have a D30 in the front. Those 2 won't interchange, the rears are both a D44 axle.
I just noticed that the Rubicon is a 2018 not sure if there is much difference in the years as far as the way they are bolted in. But I doubt if Chrysler changed to much on the suspension.
If you can cut and weld then it shouldn't be any problems.
