Wheel studs 07 4-Runner

[bwingnutt]

Has anyone seen a stretching in there wheel studs? I rotate the tires every 5,000 miles and tighten with a torque wrench to 80 ft lbs. Just had new skins put on and when I pick it up they show me the stretching in a few of the front studs. They say they only use a torque wrench when they tigthen the wheels.If they haven't been over torqued, what might cause a stretching in the stud.

I have never heard of them stretching. Did they measure the thread pitch to determine that? They usually break, not stretch.

I have the old lugs and you can clearly see the stretch in the last 1/4 inch before the shoulder.
