I pick up 5 to 6 of those vans every year with the same rims .They absolutely come off without warning .I would not have believed it if it didnt happen to me.I was test driving one with a stalling problem turned into a parking lot and wheel fell right over .There was no warning,no wobble,no noise. The corrosion between the rim and rotor hoods them solid until it doesnt.I dont know if this is coincidence or not but most of them are taxis.
