I have a 2005 hummer h2 sut and I have noticed that when I get above 70mph the truck has a vibration. I recently got rid of air bags (leaking) and went with the coil springs. I did have a new balance, rotation, and alignment done yesterday. That seemed to help, but still see a vibration. Any ideas?

 

Probably a rear drive shaft u joint.

Do you feel the vibe in the steering wheel at all?

Could be a bad cv joint in the front.

 

I do feel it a little bit in the steering wheel. What should I be looking at for a fix?

 

I was just trying to determine if it was coming from the front or rear of the truck.

From the front hard to determine over the net. Likely a cv joint. But really after that kind of shooting in the dark. Could be wheel bearing, hub or even a steering component.

Wish I was more help for you.
