Dodge vans are built using a unibody chassis, which means a lot of structural reinforcement needs to be done to make it structurally sound and have something to mount the front axle and other needed hardware to. Ford and Chevy vans have a normal frame, which makes conversion easy.

Plus you need a transfer case, driveshafts, and transmission that accepts them, plus there is no need to replace the rear axle except to match gear ratio, but that needs to be matched to tires. The unibody is not really that big of a deal in my opinion, but unibody or chassis you need control arm mounts and a redesigned suspension to accept the front axle, clearances, lift springs in front, blocks in the back... axles are the absolute least part of it and by far the easiest part to source. It's almost like saying, I have an egg so you can make pancakes, no problem. Anybody who is capable of doing the complete 4x4 conversion on a Dodge will have a stack of axles in their yard already.
