just noticed a rumbling noiseeven when i knock it out of gear at about 30 mph.sounds a bit like a wheel bearing groaning.anyone else heard this on 04 octy vrs. 42k on clock

does the noise get louder the faster you go ?

is it noisier on a left or right turn ?

could be wheel bearing , if you have access to a jack you could jack up each wheel in turn and feel for play , also spin the wheel and feel for roughness
