Well if its nothing you did with the lift kit, these steering columns have a problem with the intermediates shafts, they have too much play in them causing your knocking noise. They have since redesigned the shaft to eliminate this problem. You can only purchase it from the dealer and its relatively inexpensive, I think around 80 or 90 bucks. Hope this helps
