I have a 2wd amigo, wanted a 4wd but the fates never really helped me out. In the future once it isn't a daily driver I want to play with it. Now, Everyone always says don't do a 4wd conversion because it isn't worth the money. I was wondering if you do a 4wd conversion while during a solid axle insertion, what is the extra expense besides a transfer case and a new rear drive shaft? When doing a solid axle you would need all new drive components from the transfer case forward so what am I missing here? Is there a bunch of computer stuff that has to be done?
