Im currently having some abs issues in my 03 silverado. I think its coming from the left front but im not positive. Every time my tire rubs (barely hits the washer resi) my abs light comes on and it beeps. every time i go over a small bump in the road, the same thing happens. it only does it when my drivers front tire rubs a little so i think its coming from up there. Any ideas? Im thinking i should check my connections and the wires, but i took a look and they arent rubbing at all and look to be in good shape. kinda lost for ideas, and its extremely annoying. Any help would be great. thanks.
