Hey guys, my truck has recently developed a ticking/clicking sound coming from the front passenger tire. If I were to describe it, it sounds exactly like a stone in the tire.... but its not. I jacked up the truck, inspected each tire and nothing is in the treads (no nails, stones etc...) The sound speeds up or slows down depending on my speed, sounds like about 1 click per tire rotation. The sound stays the same regardless of if im turning or going straight. I can't get the tire to make the sound by rotating it by hand.... Anyone have any ideas before I bring it into the shop?? The truck has 9300 k's on it and is still under warranty.
