I have a nine inch rear end with a limited slip 3.25. I don't drive this car every week, but a few months ago, I noticed a slight humming noise from the rear end after the car warms up. The rear end housing looked wet so checked the lower two housing bolts and they were loose. I tightened them up and added a little gear lube but the humming still persists after a few minutes of driving. It's not as loud as before, but still there.
I'm just fishing for possible answers so could it be old gear lube or lack of limited slip friction modifier? I've owned this car for about 7 years so I don't know how old the gear lube is. Thanks.
