2001 2x4 SD 7.3 noise in rear differential only while making right or left turns. The sharper the turn - the greater the noise. After you are straight, all is well. The noise is like that of anti-lock brakes releasing, engaging, releasing. I do have limited slip, 3.73 rear. Anyone had this problem?

That is a common issue. You can stop the noise by adding some limited slip additive to the differential oil. If it was my truck, I would change the oil in the differential too.

Changed fluid to Valvoline syn/with additive 1000 miles ago. Helped, but did not eliminate problem. So I added a tube of additive. Problem remains. :|
