The right stuff must not be used on the cap nuts. The frictional qualities
are not known or suitable for torque critical fasteners. If using the
anaerobic sealant anyway, use that on the cap nuts including the threads.
You should also be using new cap nut. If not, at least chase the threads
with a quality tap. Do not fill the cap nut with sealant or oil as this will
hydraulically lock the nut before it is bottomed and the stud properly
stretched. Coat the nut face and place a small bead on the stud thread.
Final torque should about 37ft/lb. If you feel a stud that is not tightening
or excessively springing back, it needs to be replaced.
