Phil, thank you very much for your detailed reply. I have OEM wheels and they have not been off the truck since I bought it, I have no way of knowing if they were removed for some reason from the time the dealer took delivery until I bought it. I bought it from dealer stock in December and I think it had been on the lot for a while.All six wheel studs need to be analyzed by a field service engineer. I have seen this condition many times. It is not likely the wheel studs but another mechanism. First, do you have OEM or aftermarket wheels? If OEM, were the wheels removed for any reason. What usually happens is that one or two lug nuts were not tightened...probably next to each other. So you have asymmetrical loading on the 4 remaining wheel studs and one or two of these fracture which results in the remainng two or three failing almost instantly. To the eye, all six failed. A field analysis will show if all the studs demonstrate a Cap and Cone...then it is over torquing. If it is a combination of cap and Cone and irregular fracture on others, indicating shear, then it was not all the lug nuts being tight. You will also see evidence on the wheel as the lug nuts that were not tight will have lug nut seats that are wallowed out but the others will appear mildly damage or no damage. The holes where the lug nuts snapped off instantaneous will show little seat wallowing but the bore will be very scared.
Clearly something is wrong here but to blame the tech is not first line of analysis...the wheel and the studs are first to be analyzed.
One thing that you NEVER do with a failed part is to fit them back together. I know...human nature, but for detailed analysis, you have damaged the fracture surfaces and make analysis difficult if not impossible.
So again....do you have aftermarket wheels or is it OEM wheels....this is a key first step for diagnosis. If you can get pictures of the wheel flange in clarity and post here, it might help me help more than this mere speculation.
Unfortunately I only took a few quick pics of the front and back of the wheel but they're not very good, these two were the clearest. Probably not helpful. I didn't think of asking for the studs or asking to have them analyzed.
