Bought aftermarket acorn lugs made in US. 50k later theyd back off. Aftermarket lugs made with lower tolerances. Crap/rust on wheel, rotor, and bearing hub play huge part. Antiseize on studs does as well. Had always heard to put a little antiseize on the wheel studs. I dont anymore cause they kept backing off weeks later.

 

Forgot to update this.. I dont believe it was due to cheap aftermarket lugs as I had them on there for a long time without issue.

Anyway I bought all new OEM lugs and studs and that sure fixed it.
