Check your service manual again: it should say 85 in/lbs (about 7.08 ft/lbs). 85 ft/lbs is WAY to much for those studs. Anyway, now that the damage is done, you should be able to get a new stud from the dealer. There was a recent thread on this topic; one of the studs on a new KDX got snapped off, but that dealer said the individual studs aren't available for that year. If you can't get a stud from a dealer, you should be able to find something at a hardware store that will work. Good luck.
