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..
