Were you not pressing in the studs?
The original hub unit just had threaded holes. While we were installing the line and getting it tested, a wheel fell off one of the EV cars using this hub. This meant we had to source and install a bolt-press machine (we call them bolts, not studs, idk why) and make other changes to accommodate that. We’re still making the threaded hole version for the platforms where this isn’t an issue. But now the line needs to changeover periodically to run different parts with pressed studs. This adds complexity and downtime which is never great.
I’ve never seen a stud threaded into a hub. I do own car with lug bolts though. Very odd choice considering it requires extra machine processes required to manufacture that. It would be interesting to know why they felt the need to do it that way.
It’s as you described. For some reason, studs are called bolts at this company. So a bolt press is a stud press. The design change went from a hub with threaded holes for lug bolts, to a hub with pressed studs. There were some other design changes as well but that was the main one.
