Default Dampener

Is the item bolted on the left side of rear end housing on a std. C5 called a harmonic balancer? I have a problem with one and am not sure I am using the correct name to describe it. It is two steel donuts rubber mounted and bolt on with an angle iron and two bolts.

Harmonic balancer is on the FRONT of the engine, at the end of the crankshaft.

I believe it is more of a vibration dampener. I don't know what GM calls it but a parts man should be able to help you.

C5 is a 2000, there are no modifications to it. Std. Small V8, automatic, 53000 miles. Vibration at 850-900 rpms, more prevalent when the A/C is on.

Its highly unlikely that the differential damper is faulty. Deteriorating T-Tube rubber components and the engine harmonic damper are far more troublesome. What makes you think its the problem?
I think these cars just vibrate at idle. I experience it every time I come to a stop. Its annoying, but about the only thing you can do is a tune up and run good spark plugs to settle the engine down.
