I'm trying to trouble shoot this grinding/whining/"wha-wha-wha-wha" sound coming from under my 318i, it's clearly drive train because it only makes it when the car is moving.
During acceleration it more of a "wha-wha-wha-wha" sound like the drive shaft is out if balance, but when I let off the throttle/toss is out of gear/put in the clutch the grinding whining sounds starts and slowly goes away until I come to a spot.
Any way I can rule one rule one out that I'm not thinking of?
