What ever its positive effect on shank ratio, it weakens the knuckle core as a structural element. The jack's thrust is no longer being received by something mounted normal to the shank, and this situation over grows worse. It also confuses technician who continue to use it as a guideline for setting jack position under the knuckle. As the jack is being set to something other than normal, it is being pulled away from the normal line of force. Ric, you spotted right off the un-square knuckle core. The jack which is sitting well behind the knuckle's center could easily have been put there by a technician using the core as a guideline.
