Wheel Bearing Adusting Nut Size

Sorry, have never used anything other than a large pair of slip joint pliers, and yes I go by feel, have been doing it for over 40 years, Snug the nut until the wheel no longer turns easily, then half a turn back. (Old school method)

All I ever used, too. Our auto shop instructor in high school (1980) who was retirement age then taught us a tad different. He said do the same as you describe, but then said to tighten it to the next lined up slot. He said backing off was like an "old man" and not to do it that way. LOL It's always worked for me. Point is, I am sure there is more than one way to git r done.
