Scott - none of that. Imagine a small animal growling as opposed to a large animal growling. It is a bit like that, as opposed to a knock or rattle. Doesn't occur except at speed. Braking doesn't affect it. Cruise at 55, throw it out of gear and let the engine go to idle - it disappears. Road noise only. Question: will tranny gears similarly growl?? It's been a while since the tranny was serviced - but I've not noticed any unusual oil or grease drip or stain underneath..
