INSTALLATION SUGGESTION:

Grease the threads of the castle nut with Aeroshell64, and run it on, off, on your receiver extension a couple times to properly spread the grease over ALL of the threads.  Also; apply a light coating of grease to the face of the castle nut that will seat against the endplate, this will allow for proper "resistance-free" torquing, and prevent any kind of galling.

Torque castle nut to 40ft.lbs., +/-2ft.lbs.
