anybody have the specs on the rotor bolt torque. the rotors i use have a .59 bolt hole id. i have not yet measured them but am pretty sure they are 9/16 unknown pitch. i took a rotor off the hub the other day while looking for the correct rotors and did not pay much attention to the bolts thinking i could easily find the torque spec. not so easy. if i have to i will just look up sae torque ratings for the size/grade of the bolts. also how about torque ratings for the lug nuts. they are 5/8. thanks for any help.

I'm not sure about the rotor bolt you're asking about but your lug nut torque is 300ft lbs.

on the 4x4 dually the rotors bolt onto the hub. lug nuts are 300lbft??? are you sure? i knew it was pretty high as my ten year old craftsman 1/2" breaker bar fell apart and so did its new replacement. got a 3/4" harbor freight cheapo breaker bar and it did the trick.
