Hi, Does anyone know what a humming sound when decelerating may be or what part it my be coming from? This is what happened. I was driving slowly in the back yard and my rear tire side wall got cut. I changed to the small spare tire , drove to the tire shop the next day about 15-30mph for 10 minutes. Everytime I would get up to 30mph the car would start bucking like a bull and the tod lights would go haywire, so I kept at 15mph. When the dealer put the new tire back on the rear (same size.) My vx started humming when I let off the accelerator . Sounds cool like some space vehicle but I know its not good. Its been like this for a year now can't seem to find out where or what it is. Took it to a few shops they can't find it. Thanks for any info. someone can give me. Ray.
