Harmonic damper replacement

Wow what a difference. I was experiencing quite a bit of vibration from the shift and pedals idling. I also would get the occasional vibration that would come and go at highway speeds. I have gone over the drivetrain on this truck a couple times and never found any bearing issues… looking at my damper the other day I could see a bit of rubber popping out at different areas of the unit. I had a used one in which the rubber looked much better.

Pulled it and replaced it with my known good one and took it for a spin. Vibration is gone, engine has much less vibration and even less noise, it was like night and day difference.

If you guys are experiencing these symptoms and have not looked at the damper, check it out and see. The bottom one is the used one I went with. If you zoom in you can see the difference in the rubber between the two.
