Lug nuts loosening up after torquing?

[HondaFan81]

If you have had lug nuts loosening up after torquing them down, consider checking your wheel bearings for endplay. If endplay exists, replace the wheel bearings, which will prevent relative motion/vibration that loosens up your lugnuts/fasteners.

Obviously, this is a safety issue some may not be aware of.

This occurred to a local member's car that I'm working on and I diagnosed the problem.

I have never heard of this happening from a bad wheel bearing. I've replaced 100's of bad wheel bearing on almost every kind of car none of which had problems with lugs loosening.

Crusty hubs/rims
Improper torque
Wrong bolt patteren (close but no cigar)
Wrong style lug nuts
Cheap wheels that require centering rings (and the rings are missing)

That's what I have seen personally cause it
