2006 GMC Yukon Chirping

Flagcoach · August 10, 2016

I have a 2006 Yukon that we love, but recently we have been having a few issues. All of a sudden I have a horrible chirping/ticking coming from under the hood. It seems like it is on the drivers side (but that could be because that's the side I am on). I have run Risolene through it thinking it is maybe a lifter. I have replaced the tension pulley and another pulley that had a little noise. Belts look good. I am still having the issue. It gets louder and more noticeable as I am accelerating (super embarrassing at stop lights). It seems to get better once the RPM's drop, but maybe there is just enough road noise that I can't hear it. As mentioned, I love this truck and want to make it right. Any suggestions.

I have included a clip. You can kind of hear the clinking chirping. As I accelerate it becomes more pronounced. It sounds like it is coming from near the bell housing.

Thanks for everything!

Try again,the clip didn't make it.

Thank you to everyone who looked at my post. I apologize the clip did not come through. After more research I have found that the starter splines are not lining up with the flywheel causing the horrible sound. I am putting a new starter in this afternoon, and I am hoping I can just enjoy my beauty of a ride again. Thanks for everything!
