Hey, my truck has started some things lately that I don't know exactly how to fix. Not long ago I had to replace a sensor, because my speedometer stopped working. Now I am noticing that the truck does sort of a jerking motion while driving, more so when I'm in a higher gear. Also the ABS light comes on occasionally, and when I hit the brakes I hear a strange ticking noise coming from somewhere behind the dash, or maybe down from my brake pedal. I'm thinking I need to replace a sensor, but if anyone else has had these specific problems I could use a little help please! -Caleb Hart.
