Wheel separation

I haven't read up on this in quite awhile, but I thought the majority of these were related to bearing failures. I frankly can't remember the last time I've seen a stud issue with hub pilots. Yes, you occasionally have to replace the nuts, but I've always just checked them at tire changes.

As far as geographics, look at states where they use the liquid de-icers and where they have more freeze/thaw cycles (more wet roads in winter.) I'd suggest talking to some large fleet maintence managers in Michigan, there's plenty of them that stay in-state and Michigan fits the bill on the deicer/freeze/thaw cycle

 

there's anouther thread here about the same thing

although i think it was related to a budget truck rental accident


the studs rarely fail in the way you are inquiring, more likely wheel bearing/hub, kingpin or other catostrafic failure

 

I drive off road in the oilfield on some really rough roads hauling 100k plus payload and that is probably part of the prooblem but I havve lost 4 sets of duals off of the same trailer in 3 years because of studs breaking. I do the brakes three times a year on that trailer and always replace the studs and nuts when I do the brakes but I will say this I hate hub piloted wheels.
