Just got my 2000 suburban's wheels rotated balanced and aligned. Now from 45 to 55 mph the steering wheel will shake out of my hands. It doesn't happen all the time and it seems to be set off by bumps. If this sounds like anything anyone has encountered before please let me know some info. The Alignment was way out of Camber for a while would have messed the tires up that bad that it would do such a thing? Please any info would be helpful.
