5th Wheel Broken Stud Theory

Although we are currently running a Class C, several of my camping buddies are pulling 5th wheels. They keep having problems with broken wheel studs with the aluminum rims. They carry torque wrenches and are religious about checking them, but still occasionally break a stud on our trips. We generally write it off to cheap metal studs and heavy trailers, but I have another theory.

They all use those "super grip wheel chock" stabilizers between their tires when parked.They tighten down the threaded rod which pushes the tires away from each other. It holds the trailer still, but there is no torque wrench used on them. Trailer suspensions are designed to have some vertical give as the tires hit bumps on the road, but I don't see much lateral give except the bulge of the tires when you crank one of those chocks down. Is there a chance that continually using these are actually weakening the studs which eventually snap?

They say I'm smoking crack with that theory, but they can offer no explanation why. Please explain to me why this theory is wrong.
