At work I verify torque at times, we would use a patern specified by the flange manufacture followed but another round starting at number one going clockwise for a single click until a complete round can be completed without additional movement. After that we would follow up by 3 more bolt tightening.
I have contacted MCI about purchasing new Air bags, still trying to locate 2 rear brake chambers. They do not have the studs, inner and outer lug nuts.
I need to make a trip to MD and back to Texas and then I would like to make the replacement.
