vibration under acceleration - flex disc?

[jst2878]

I had this same problem. It took me two different shops, the later having a roadforce wheel balancer. They resoved my problem by finding two bent wheels that were not identified by the first"inexperienced" tire shop. Give this a check at a place with the premium wheel balancing machines. When the x is lifted up take a quick look at the flexdisc and look for tears, but it's prob not that. Good luck
