As of early last week I noticed a ringing sound coming from the front of my truck. Or what seems like the front of my truck. First it started at 50mph and would quite completely at 60mph. Then the next day it would start at 30 and stop at 40 and so on and so forth. The only way I can describe this sound is like running your finger around the edge of a crystal wine glass. It started after I picked up my truck from the body shop that a close friend owns but on the way to the body shop I hit a pothole that was unavoidable. The truck doesn't drive any different and still runs very strong. I just wanted to see what you guys thought before I just drop it off at a shop and start throwing money at it.
