2007 LTZ 173K miles.
I am hearing a strange whoop whoop noise coming from the truck under certain conditions. The noise is not very loud but loud enough to be noticed. It sounds like its mainly coming from the front left but it could be anywhere.
These are the conditions I am hearing it from:
- Turning to the right...even slight right. Never seems to do it turning left.
- When hitting a nice size dip in the road. More noticeable if truck is really loaded down and heavy.
- From a stopped position. Slowly rolling back about 6' and slamming on the brakes. You get a whoop whoop.
The noise does not really sound metallic IMO. But it is repeatable all of the time. I also think I can feel it in the steering wheel when the noise occurs. Also it does it either braking or not breaking.
A year ago, I replaced the replaced lower ball joints but not the arm (bushings), upper control arms and rear shocks. Last week, the motor mounts and tranny mount were replaced for the typical busted mount symptoms. Tires are Michelin and were installed about 2 years ago and have plenty of tread left.
Thanks guys.
