Guys, there is no metal on metal. The bolt is 5" long but the sub-frame is only 5/8" from the diff cover and the sub-frame is about 3" thick, no real leverage. I have a hard time believing that the OEM 3 mounting points flex enough to cause my bolt to be a problem. I think of it like a heavy load spring in a leaf pack on a pickup truck. It doesn't really do anything until there is a lot of load applied and then it should just help carry the additional load. If it is going up and down that much why are they not using the proper mounts (other than they are cheap and the occurrence is rare) which again means my bolt shouldn't "hurt" anything. I do appreciate the feedback though...
