The AW4 is around an inch longer than the AX15. This will probably require you to lengthen your front driveshaft and shorten your rear driveshaft. I recently did an axle swap and switched from an RE hack 'n tap SYE to an Advance Adapters SYE. My rear driveshaft is actually 2 inches longer than it was before. My front driveshaft was lengthened almost 2". Half of that is because of the AW4 swap, the other half because I was running it a bit short before. Keep this in mind. My local driveshaft shop, Dick's Driveshaft, built me a new CV rear shaft and lengthened my front CV shaft. Please see the table below for a breakdown on the cost of the swap.
