Safety Tech Tips - Wheel Torque

[cjbcpa]

I don't think a stud could get dislodged. They're not threaded in like exhaust manifold studs (at least on my car). If my experience is typical, they are inserted into the hub from the rear and are indexed with splines to match up with straight grooves in the hub (there is a flange on the rear of the stud that acts as a stop. As you tighten the lug nut, it actually draws the stud tighter into the hub. As a result, over tightening can cause the stud to stretch, weakening it. If they were threaded in, I imagine we would all be familiar with stories of people backing their studs out, but I've never heard one.

This is a picture of what I'm describing:
