How many miles do you guys have on your trucks since you "removed" this part? I've not seen/heard/felt any ill effects from it not being on there either. However, if it is there to cancel out small vibrations, what effect will those small vibrations have on the other drive line parts after 30k-40k miles? I'm just wondering why they would go through the trouble of engineering and producing these if they really don't do anything at all. That said, if they don't replace mine under warranty I'm sure I'll just toss it as well. lol
