I did a search with no success. I need to know the proper torque spec for a 12 bolt. I am looking for the spec that GM used when it was built. I am not a fan of counting threads or any other crazy ways. Anyways, I have already removed the nut so the only way to get it on right is to torque it. Also - Why does everybody say to replace the nut? I have not heard of this before I joined this site and am very interested in the theory behind this. Anybody care to shed some light on this?
