Glad to hear you found the source of the problem! We will all keep and eye out for this now.

 

Good to hear that it all worked out and that the Big O took care of you properly.

One more point - I'm surprised that they had a problem with the wheel studs! I always check the torque of my lug nuts after they come back from the shop. The correct torque is about 85 lb-ft. It's easy to over-torque the nuts with hydraulic tools. So, when it's time for tire replacement or wheel balancing I often do the wheel R & R in my garage and just deliver the wheels to the shop.
