I have a 2007 Hummer H2 Suv and when its in park idling if I touch the brake pedal or turn the steering wheel it vibrates really hard and makes clicking noises that sound like the fan hitting the shroud. Does anybody have any idea what this could be? Any help would be greatly appreciated.

 

Check and see if the power steering fluid is low.

 

I checked, the powersteering fluid. It was fine. I took it to the cadillac dealership and found out that my powersteering pump was going bad on me, they replaced it and my extended warranty covered it. Now im back up and riding again! Thanks

 

Glad it was a cheap fix for you.
