Confused, your last post stated you got it to about 240 ft/lbs. Now you say 180 ft/lbs and then it breaks free. I have never done one of these but just following the thread to learn.
To me it does not sound good from reading other posts similar to this.
Sorry I could not be any help but do a search as I know others have run across this also.

thats exactlly what Im talking about. Breaks free at about 180 or so everytime. Im thinking about getting some all thread rod to use all the threads in the snout and using that to seat it on the rest of the way. 618hawk makes a tool. Then Im gonna grab a more threaded and even longer bolt to hold it on. Torque that to 37 ft lbs and an extra 120* lots of lock tight.

Like I said the bolt was not cross threaded. It threads in fine and still does it just breaks free at 180 lbs. I don't know what might have been done to the car before me!

The bolt totally breaks free. un screw it and there is one perfect un broke ring of thread wrapped around the end of the bolt.

yep a couple must have. but im thinking if I can get passed those threads with an all thread rod installer then it might work to seat it the rest of the way on. Once it's seated then the bolt itself is only torqued to 37 lbs plus 120* turn so thats probably not to close to my 180 lb mark were it breaks free, you dig?

They're all bad. It's an illusion. Just because the bolt won't pull straight out by hand doesn't mean the threads are OK. It's very common that threads "flatten" a bit and won't handle the torque.
