Hey Todd...No I don't think so...Only four of the rockers are affected. The studs are plenty tall and there is plenty of thread engagement....

I am going to replace all of them, It just bugs me to not know what caused it, because it seems like such a strange problem. I am leaning towards there being a material issue (abnormally low hardness) on the trunnion, the poly locks don't even show a mark on them. As was suggested I will check the rockwell reading on the affected trunnions vs. unaffected....I still would like to know who made these rockers, as well...
