My friend's M1008 started to have a loud rattle. We pinpointed it to be coming from the harmonic balancer. It looked ok, but we decided to remove it and try the one from my old 6.2 (just to be able to run the truck until all parts for the serpentine swap are complete). Upon removing we noticed the balancer was rubbing the water pump housing. How can this happen? My old balancer does the same. There seems to be no play on the shaft.
Can these go out of round or does the rubber get stretchy (can't get any movement in it by hand tho) making the outer ring bounce around? The waterpump was replaced a couple of years ago and the bottom housing seems straight where others have a little curve there. If it is the waterpump housing, the rattle should've been there before. Pretty sure we would've noticed the rather loud rattling tho so I kinda doubt that that is the issue.
Any ideas?
