In this video I fix my 2005 GMC Envoy, which is also like a Trailblazer, from a common whining noise issue. What I first thought was a power steering pump issue actually turned out to be a simple idler pulley fix. I replaced the original idler pulley with a genuine ACDelco unit and it worked perfectly. No more whining noise and it cost just about $25.

**EAGLE-EYED VIEWERS**
You may have noticed the pulley coming off the engine was different than the one I showed as the comparison with the bad bearing. This is because the pulley that I pulled off the motor was an old part I had laying around that I threw on while waiting for the new part to come in. The pulley I showed with the bad bearing was indeed the original part that was causing the whining noise.
