High Speed metalic noise & vibration
midwestdave33 posted a topic in 2014 - 2019 Silverado & SierraI have a 2014 6.2L LTZ Wheelchair Accessible Silverado built by SVM Mobiltiy and I'm having a VERY loud metallic "clanking" or "vibrating" NOISE when I hit the speed limiter in my truck at ~100mph. The truck is still pulling hard @ 100mph and the onset of the noise is NOT gradual its sudden and immediate and very audible. Does anyone else have this issue? At first I thought driveshaft vibration or a warning noise from GM when speed limiter was reached... PRE-EMPTIVE STRIKE: -Yes, I do this on private roads -Yes, the dealer has inspected both road force and the driveshaft and have found no issues. -Yes, I'm in a chair from a car accident. -YES, I have safety equipment including a 5 point harness. -NO, I was not driving, my father was. and no we weren't speeding, it was caused by a blowout. -NO, that did not take away my love of racing. -YES, I HAVE SPEED RATED TIRES ok, I think that covers the pertinent details....
