Breaking wheel studs
Thought I would ask the collective for help. I have now had 3 lug nut wheel studs break. Rig is a 34ft, 14,400 GVWR with 16 inch 8 lug aluminum wheels, studs are 9/16"dia. Studs have broken only on...

One other possibility that I just thought of. If a shop used a pneumatic gun even once on the lug nuts, they could have fatigued the studs with an over torque situation and they all should be replaced.
4. What TucsonJim said ^^^! Chris
Yup!
Sounds like good ol Les Schwab at work.
Watch them, they use the impact to run the nuts up then hit the studs once each and the torque wrench does not rotate!
Bottom line they are over torqued before the torque wrench is applied.
Exactly how it was for me.
