Starts and Idles fine. When driving, there is slight vibration and sound that increases with speed.
The best way I can describe the sound is that it sounds like I am riding on heavy-heavy snow tires or monster truck tires.
I can't tell where the vibration is coming from but I can feel it, I think it is coming from the front end. I am not sure if it something to do with the axel, belts, transmission or anything else that turns or increases with speed.
At certain speeds above around 35-50 miles per hour the sound and vibration go away for a little while.
Any ideas on what I should check or read to diagnose this problem.
