Anyone have a diagram of how this thing looks from a side cut away type view? I am in Sierra Vista AZ and had the center support bearing installed before leaving Montana. Now after getting here okay, there is a loud clicking sound coming from the center area of the driveline. What's inside at the center support area and connecting shafts? Is there something that may have come loose in there? Also need to know what size wrench the triple square bolts take and what else do they call these bolts (hex, star)?
