Got The Shakes

[imnutz66]

Have an 08 Sierra vith a vibration problem since new - first trip back to dealer, balanced tires, vibration became intermitent above 45 - would be decent for 4mi then shake for 1/2mi, go back to ok for 4mi, then shake again for 1/2mi. this was with cruise on at 65. 2nd trip to dealer, road force balance, replaced 2 tires (wrangler st), now above 50 mph vibration is steady and doesn't vary, only with speed. Any one had this problem? Any ideas?

thanks

I had a S10 Blazer that drove me nuts over a vibration,we changed tires,rims etc.Finnally figured out it was the torque convertor.Changed it out and not a problem after that,when the trans built up press. the torque conv. would just go nuts shift into o.d or not ,jump back and forth etc.Could allso be in your brakes somewhere.
