2011 DD13. Does the vibration damper wear out?

Hi guys. Like the title says, does a 2011 dd13 dampner wear out? I wasn't sure if it is like a harmonic balancer as in a fluid or something does the balancing or more like a fixed weight that doesn't go bad. I have a bad engine vibration and it is there moving or not. So I was wondering if I should buy a new one. It doesnt look too hard to remove and install. The other thought I have is maybe the pressure plate is off center, but I don't know how to check that. Thanks, Rob.

 

Thanks, the truck got a new crate engine before I bought it. But judging by the amount of things bolted to the engine that I have replaced (egr valve, actuator, cooler, radiator, well you get the idea) I doubt they put a new one on. The engine has about 140,000 miles, the truck has about 700,000 miles.
