I still stand by my statement “at least some reason why one is $100 more”. I didn’t quantify exactly how much better for an extra $100, but if your ok with a $38 water pump in “your” truck I am too.Can't help but wonder if the bearings are different. Maybe not "$100 different" but different enough that one's likely to last much longer than the other.
But how does one tell? Crap...
