I have a pretty good vibration only in the front of my vehicle. Tires have been balanced, alignment done.etc No audible noises such as clunks, roars, howling.etc at all. Only vibration/shudder. I ask is a wobbling harmonic balancer normal because I know if they go bad they can cause the engine to vibrate pretty roughly. Also harmonic balancers are overlooked when mechanics go to diagnose the reason for a vibration. I happen to catch this myself while I was laying under my vehicle with a flash light. The pulley in front of the HB is not wobbling, just the HB part is wobbling. 2000 Ford Explorer AWD 5.0 V8
