For those of you with AWD, is it normal to have a little drivetrain growl on the highway? I have never had an AWD car. I have owned plenty of 4WD trucks and I know there is a little front differential growl out of them on the highway, but figured the Caddy would be real quiet. It is a similar growl, so maybe it is just typical for all AWD/4WD's ? Or maybe there is a TSB out there to fix this on 2008 cars?
