Hello all , well my car is acting weird again. When I am driving down the road I am getting a whirring sound from the rear end of my car, the noise is still their even if I shift it into nuetral and coast. The drivers side axle bearing went bad on me a few months ago and I replaced both bearing and seals, when I reassembled it I just coated the bearings with gear oil, should I have packed them in wheel bearing grease?. Any ideas would be apreciated, I will be working on the car friday.
