What to do if your harmonic balancer is wobbling?
When the harmonic balancer is wobbling, it would be best not to run the engine. The harmonic balancers function is to counteract the vibrations in the engine so damage doesn’t occur.
Can a bad harmonic balancer cause an engine to shake?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
What is the function of the harmonic balancer?
The harmonic balancer is an engine component found on virtually all rotating internal combustion engines and plays an important role in protecting the engine from dangerous harmonic vibrations and potential damage.
What causes a crankshaft harmonic balancer to slip?
The harmonic balancers found on many vehicles are constructed as two pieces of metal with a rubber layer in between to dampen the vibrations. If the layers separate or slip, the timing marks, which are usually stamped into the front of the pulley, can shift and thus throw off the placement of the timing marks.

How does a harmonic balancer work on an engine?
Also, the harmonic balancer has a pulley (either integral or bolted on) that connects to the engine’s drive belt. When the engine is running, the pulley turns the belt, which, in turn, causes the engine-driven accessories (alternator, A/C compressor, etc.) to rotate.
What kind of noise does a bad balancer make?
A faulty balancer can result in a knocking, rattling, or squeaking sound that corresponds with engine speed. In some cases, the noise is bad enough to be mistaken for an internal engine problem.
What happens when a harmonic damper goes bad?
One automotive part that frequently gets overlooked is the harmonic balancer (also known as a vibration damper or crankshaft damper). Although the component is often forgotten, when it fails, it can cause major problems—including severe engine damage.
