A week ago I am driving about 20 miles an hour from one light to another and hear a loud pop. I am almost positive there was nothing in the road. The rest of the drive to work I monitered all gauges and they are normal. When I got home that evening rolled under it just to check and could not see anything that would explain the sound. Still to this day everything is operating normally so I am at a loss. On one hand i am relieved everything seems okay but on the other hand I am still concerned about what caused the noise.

I would call Road Side Service and have them tow it.
