Taken from another thread I posted this on discussing these bolts:
"Looking at the pictures OP posted of his bolts, they are "Class 11T" [the four lower ball joint bolts] based on the markings as per the service manual page 130 (SS-1). On the following page, the standard torque for a Class 11T M10 hexagon flange bolt is 72 ft lbf. 64 ft lbf for a hexagon head bolt of the same class and size. Therefore, torquing them to 59 ft lbf would be completely understandable in my opinion so long as you verify your bolt grade".
This only applies if you are using Toyota fasteners. Check your bolt head markings and compare to the service manual or the above quote.
