Right now my Cherokee is only 2 wheel drive but i'm already workin on getting all the components to do a 4 wheel drive upgrade. And yes I know it's easier to just buy a 4 wheel drive version instead of doing the upgrade, ive been told 100 times already how much of a headache it'll be, but frankly I don't care lol just makes me wanna make it 4x4 even more just to prove the doubters wrong!
