Bad Vibrations

Chat up some of your friends or mechanic who know the difference in the feel of a wheel balance issue vs. a driveline vibration. Go for a drive-they generally are distinct from each other. Driveline vibration is generally higher frequency than wheel balance, but both are relatively low frequency. It is hard to describe but driveline vibration is frequently audible as a low frequency constant booming noise, possibly a rumbling. In a bad case it could cause stuff inside to rattle with the vibration/sound. Wheel balance is lower frequency (wheels turn slower than driveshaft).. more of a shake which can also set off rattles.
