So I was told i need a new transfer case. Our issue is that it won’t move when we put in into 4wheel drive, is like someone chained it to the ground. Runs great and normal when not in 4wheel, I can barely pull the handle up to shift into 4wheel. Don’t mind looking for a used one and rebuilding it, unless there are other things I should look for first? 2006 TJ 65k miles, 3” lift.
