You definitely need the cv in if you want your wheel to stay on. If you rip out the diff/cv's and the tcase, you might as well run some 2wd spindles so you don't have to worry about the wheel bearings.

 

It'd be easier to buy a 2wd and transfer all your mods and then sell the 4wd.

 

it is already beyond turning back. i am installing a 4 link in the rear this week. i know that it is not going to be easy,but the easy way is for lazy people, or maybe people that are smart. not sure.in my case i am going to stick with the first one.
