After replacing the water pump on my 02 2500, I noticed a vibration around 1500 rpm, if I put it in N and coast and hold the rpm it seems to stay the same. The truck idles fine no vibration, no smoke, and no starting problems. The alignment pins were a bit sloppy? How much off center would the HB have to be to cause a small vibration? and when I put the balancer back on, the washer on the balancer bolt was too large for the bolt? looked like there was a part missing? I doubt a washer in an eccentric position could cause this?
Thanks for looking!
