It shouldn't make noise. If it does, replace it!
I would contact the local parts store and replace the harmonic balancer if you think it is bad. a bad balancer can cause failure in the crankshaft bearings because of the shake.
Am unsure of what you are asking. The harmonic balancer is a lifetime part of the engine and does not need replacement based on a time or mileage requirement.
You dont repair it...you have to replace it.

you don't -Buy a new one
There is not much you can do with a bad balancer other than replace it with a new one.
Remove belt, balancer bolt and get a balancer puller to remove the balancer. Unbolt and unplug sensor to replace it. An air impact wrench that is strong will get the bolt loose.
