I have a 2010 JKU Sahara with the 3.73 gear ratio. A friend of mine removed his Dana 44 rear axle that also has the 3.73 gear ratio. Would I be able to remove my front Dana 30 axle and replace it with this rear Dana 44 without any other modifications? If this can be done, is there any other differences (in axles) between the Sahara and the Rubi? Thanks for the help.
