Hello all! Have a 2008 Chevy Silverado 1500 Z-71 4x4. 3 Days ago a noise started when I turn only right. It sounds like I'm driving over very fine rumble strips. Only does it from about 30 MPH and doesnt seem to get any louder as I go faster. It does very well seem as if the sound gets faster paced, but not scaled.(when going 30 the sound is not half, of when I am cruising 60) Truck has the extended warranty, but really don't want to deal with the dealership unless I have to. Any thoughts as to what I can check out? I've checked fluids, tire pressure and for debris. The sound almost sounds as if my Michellin LTX tires has a baseball card scraping against the treads. Best way for me to describe the sound. Thanks in advance for all your responses. I've done quite a bit of searching, but have not seen anyone with the sound as I have referred to. P.s. I feel no vibration in the cab what so ever. Just a light humming/vibration noise.
