Had the left rear wheel part company with my truck Saturday morning on my way to pick up a treasure with my tridem gooseneck trailer. 7 of the 8 studs sheared off flush with the rotor surface, last 1 just below the nut. 4 of the 8 had indications of metal fatigue (different colored areas in them). They came up to torque nicely 2000 km ago-and gave no indication to their imminent failure until I was unceremoniously pitched into the oncoming lane when the wheel left. Very lucky that nobody was coming, either to collect me or the wheel assembly.
This truck may be the poster child for this type of failure. 450000 km of oilfield use and abuse, most of the time at 8000-8500# and running 35" rubber. I never even considered changing them out-now I won't move the truck until I do all 16 on the rear. Fronts were changed out with the wheel bearing assemblies probably 100K ago, so I'm not as concerned with them. These were always torqued to spec by me-can't say about tire monkeys or the dealership for sure. The day before, I had an '05 up on the trailer and too far forward-I think the extra pin weight started the failure.
Buddy of mine who hauls RVs has heard of the same thing with extended mileage. I'm adding them to my list of maintenance stuff, and Dad's '98 3500, which did a lot of trailer towing before he had it as well as presently, and has a pile of km, is having the parts ordered tomorrow to change out all 48.
