If you torque a lubed 10.9 m10 1.5 bolt to 52 ft lbs you have over torqued the bolt if the specs is 52 ft lbs.

If you torque that bolt to 52 lb-ft you have over-torqued it, period, no matter what the spec.

Virtually every bolt on this car seems to have come from the factory in a size and grade that accommodates its specified torque with lubricated threads with room to spare. Importantly, this includes these body mount bolts, which -- as I keep repeating over and over -- are Class 12.9 bolts, which will accommodate 52 lb-ft with lubricated threads.

As for the rest of it, I think you protest too much. I'm not exactly sure what it is you think I'm saying that you disagree with. Most of what you're saying, obviously, I already know and agree with.

I really wish you'd do some reading, ( https://www.fastenal.com/content/feds/p ... Design.pdf page 11) and here is the torque chart for a 10.9 m10 1.5 which is 53.2 ft lbs dry http://www.fastenal.com/content/feds/pd ... teners.pdf If lubrication was not mentioned then it always a dry torque value. If you toque a bolt that was given a dry torque value and you torqued it to that value with adding lubrication you have over clamped the part. But in the mean time please answer this....they give you lower torque values for a bolt that is lubricated, how does lubrication weaken the bolt?

That explains it, LOL. :lol:

That's mutual....

Where is that stated in any General Motors documentation that has anything to do with these cars?

Who said it does? Over-torquing will weaken it, obviously.
 
That's what I'd like to know. :mrgreen:

But how does this qualify as "talking" ?!? GAAAAHHHH!!! :rofl:
 
One thing I would like to know, though. Maybe this belongs in another thread, rather than hijacking this one....

As I've said (so many times I've lost count), I found class 12.9 bolts in my car. These were installed in positions 2,3,4,6,7. What have other people found in their cars, 12.9 or 10.9?

We know that not all models from all divisions had bolts in all five positions, some were missing 3 and/or 4. Maybe some cars had lower spec bolts. Either would be a way of "tuning" the mounts.

Heck .... where is it stated anywhere period, let alone GM docs?
 
So if I get the cheaper bolts, what toque spec am I using? And is it a lubed or dry spec?
