My harmonic balancer was replaced by the dealer after they thought that is what was making the noise in the first place. It doesn't look that bad to me. Iv seen much worse condition others have posted of their pulley. |
Your harmonic balancer does indeed look good from the picture. Sometimes though looks can be deceiving. If it was defective in another way (aside from the well documented tearing), the it could have had an effect on the bearings. Replacing the balancer could have solved the root of the problem, but the damage was already done (assuming the balancer was the issue).
