Re: crankshaft pulley (hormonic balancer) wobbly ?
The harmonic balancer/dampener is a failure prone part on the V6. A loose bolt is usually not the problem. The inner and outer parts are bonded by rubber and the bond breaks causing the two halves to separate, often with devastating results. I would replace the part immediately; around $170 at the dealer. Also, do not reuse the old bolt, get a new one at the dealer, use Locktight, and torque in steps as specified in the manual. I have seen one failure result in a broken crankshaft snout, a big time problem!
