Why is my car vibrating at high speed?
Why is my car vibrating at high speed? Vibrations in a car going at a high speed can be caused by numerous issues. Most of these issues are found in the front end of the car. Vibrations in cars are usually experienced in old cars, but they can occur in any car, regardless of whether it is a sprightly new impulse buy or a battered family heirloom. Why does my cell phone vibrate at high speed? Since I don't typically use any higher than 2500 RPM in highway speed, I suspect that it's somewhere around transmission, I'm not really sure...
