Has anyone else had problems with the pulley shaft on their power steering pump snapping? I've had it happen 3 times now. Truck is a bone stock 2000 1/2 ton 5.3l 4wd w/ only 165k miles. I'm running stock size tires and don't go off road or anything like that. I'm using Delco reman pumps from different suppliers. (First one was the original, then one from Rockauto and now one from O'reileys.)
