The clocking ring is what allows for different installation angles, as well the as fine-tuning of ground clearance and fit within your particular vehicle. The bolts were threaded in hand-tight and then the transfer case was test fit to the vehicle. Once we were happy with driveline angles and clearances, we removed the transfer case and tightened the bolts into the clocking ring. It took some effort and is best to remember that they are interference fit threads. While they may feel like you cross-threaded the bolts, it’s just how they work.
