the bolt for the water pump seems to screw in correctly and tight but they found that there is a slight wobble when the pump runs

mechanic thinks it was a defect from new, has 45,000 miles on that pump now, so probably just finally wore out from the wobble

not sure of the brand, it was oem though

getting another oem - think graf- hoping this one will be better

if another water pump issue pops up again before 75,000 miles or less think i will just bite the bullet and buy one from the dealer

thanks for the suggestions
