Little set up info:

OK, so I'm doing front shocks on the Expedition. Looked in the Haynes manual and it has a range of 35 to 46 lb-ft for the top bolt on the shocks. Set the torque wrench to 40, middle ground should be fine, so I think, then it went south fast. I busted the threads off the top of the shock. Now they are just Monroe Reflex's, so I'm not out a lot of money if Monroe or the retailer will not replace it for me, but am/was I factoring something wrong. I wouldn't think the rubber donuts would matter that much, and I'm pretty sure the wrench is correct as I purchased it new the same day as the install. It had me so razzled, that I put the old one back on, and torqued it and the other new one to 30 lb-ft just so I didn't do it again and can hopefully drive to/from work until I get another one installed.

Now does anyone know if Haynes numbers are off, or did I possible get a bad shock or is 30ish an OK number to torque the shock?
