I replaced the water pump 2 years ago with a carquest unit with a lifetime warranty. When I was recharging the AC I noticed that there was a quarter inch of oscillation at the fan. It spun smoothly on the clutch, but when the pump was turning it had the movement.
So I removed the pump and found 30 thousandths of radial runout at the tip of the flange Somehow the front bearing shifted.....
New pump from warranty exchange has 5 thousandths in. radial runout and 3 lateral runout, so even the new one isn't perfect. I don't think the quality control at the Mexican factory that made the pump is very high.
Has anyone else checked their pumps to see how well made they are? I'm disappointed in Carquest - I hope I don't have to replace them every 2 years......
