I have a 92 with a three inch lift and mine did the same thing... actually there was a kind of grind and pop, especially when turning left. I initially expected the steering column also, but it turned out that the grinding was the trac bar mount. The bolts were loose and the rubbing had stripped them so I replaced them with two new grade 8 bolts and some lock washers and the griniding was gone. The popping sound was actually coming from the joint in the trac bar, and when I replaced the it the pop was gone.
Your situation might be a little bit different as I was still running the stock trac bar on three inches of lift. It was doomed to fail.
