Grinding noise during cold mornings
I have a 2005 Saturn VUE, 3.5 L, V6 (212 CI), FWD, with 186,000 miles that I purchased used in Michigan from a GM Dealer about a 7 years back. For the last couple of months in the mornings especially when the car is colder I get a grinding sound coming from somewhere in the middle to front end of the vehicle. After I drive for 10 minutes or so and or the temp is warmer outside the noise stops to exist. It only makes the noise when I accelerate and the car is moving. I have already had the wheel bearings and front suspension parts replaced....
I have sped up and taken my foot off the accelerator and the car feels as if it is backing off with a whining sound and grinding.... please advise...

 

Take the belts off and spin each pulley. It sounds to me like it could be a tensioner or pulley.

 

I have same problem, but it's a much deeper sounding cruching grind than a tensioner or pulley.
