2000 5.0 V8, AWD, 132k miles. Started suddenly the other day. Coming from the rear only when turning somewhat sharply and accelerating.

 












I'm guessing the differential clutches need servicing.

Thank you! I did a little searching and believe you are right. I have a slow drip from the differential, so this all seems to be related. I had been putting off changing the oil, but will do that this weekend and add a friction modifier which some folks also recommended. I have no experience with differentials, so I did not even know there are clutches in there!
 






I replaced the differential fluid, including the additive and in a few miles of driving the noise is still there. I'll drive it a bit more and see if I get lucky.
