I have the same problem on my 2003 GMC Sonoma. After 30 minutes of freeway driving the car starts a high speed vibration that increases until i slow down substantially. No hot tires and had the brakes checked. It started after the brakes were checked for what i thought may be caused by them. I had a clunk sound when i came to a stop and let off the brake. that stopped after the first brake service where they basically cleaned out the dust and re-adjusted them. The high frequency vibe is a little un-nerving and makes we worried to drive. Any ideas?
