Hey all.. My opal has a small shimmy in the front end. I don't beleve it to be tires. I remember a post about a shimmy that occurs between 70 and 90 mph.. this is what is happening. Any help would be great on where to start looking. Car has been aligned, and tires rotated and it sill shimmies in the same place. Thanks! Adam J. Green '94 Opal and Emerald MTX
