Makes a noise while rolling.down the road. It only does it when the.truck is. Moving. The faster it goes, the faster the noise is. There is no shake or vibration.

What is your question?

If the truck is rolling it makes the noise. We ruled out a bad tire. It kind of sounded like a knot on a tire. No shaking.or vibration. The truck still drives great except for the noise.

What makes this problem better or worse?

The faster you go, the faster the noise goes.
