Can a bad harmonic balancer make a knocking noise?

A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.


If the rubber gasket on the harmonic balancer is ripped up will this cause a bad knocking noise How do you replace it if need be?

Hard to say. However, if the "rubber gasket" you're talking about is the center bushing on your harmonic balancer, that could throw your Harmonic balancer out of balance. This could easily make it shake to beat the band which in turn could be the knocking noise you're hearing. I suggest you get it looked at immediatly. If that is what happened, your engine won't survive long.


If the harmonic balance is bad can you repair it or replace it?
