OK, I'm suspecting that I have a bad Harmonic Balancer in my 2000 f150 4.2L. The pulley on Harmonic Balancer is sticking out about an 1/8" farther than the rest of the accessory pulleys. The miss alignment is chewing up belts.

I did a search for Harmonic Balancers on various parts store websites but have been coming up with blanks. Does anybody know if this is a Ford only part? Or am I missing something?

 

I have only bought balancers from ford. I would make sure that the bolt that tightens the balancer to the crank is fully seated, you might not need a new balancer. You should use an impact wrench though, it will tighten the bolt but won't turn the crank.
