Hello. The crankshaft pulley and harmonic balancer is one unit on your vehicle. There is a strip of rubber that separates the two components, that will perish over time. This is typically why it begins to wobble. You will need to have the harmonic balancer replaced before any more damage is caused to the engine. This is a common problem associated with this generation of engine. A technician from YourMechanic can come to your location to inspect the shaking issue and guide you with any needed repairs.
