8 1/4 torque specs

Hey guys ran across this. I am new to this so please excuse my ignorance i am learning as i go. I just replaced the pinion yolk and a manual says 170 Ft/lb of torque on the nut that retains the yolk. I wanted to make sure i wasn't confusing it for what yall were talking about? also what are the torque specs of the 4 small bolts that hold the UJoint on? i hope i used correct terms. Thanks again for any help.
