anyone had this problem before? 03 expy xlt when the truck is at a complete stop or i'm about to take off if the tires are turned i can sense a little rattle or shake sort of like if the tires are gripping the ground that good. it's been like that since i got it. after i got it ui put on another tires only work i'v done is the front brake pads also it's NOT a 4x4. any advice or suggestions are appreciated thanks. oh also if the tires are straight you won't feel it ... also it could be the same issue but if i stop like in gravel but i'm going a couple of miles per hr doesn't seem to stop well i feel the same problem thats with the tires straight though. sorry buot the long post :
