HELP. Pressing Ball Joints Back In (Pictures added)

There IS a torque spec for castellated nuts. However, you can rarely get the slots in the nut to line up with the cotter pin hole in the stud, so, what you do is, torque them to the proper spec, then, if the slot is not aligned, simply tighten the nut to the next slot and line it up and install the cotter pin. NEVER under ANY circumstances loosen the nut to align the slots. Always tighten to align. It will be a little over torqued, but will not loosen up.
