rear end noise

When changing rear end oil is the additive you use to quite rear the same you would use in a posi rear end?

i added a 7 oz tube of the friction modifier to the 75w 140 full synthetic gear lube in our 2002 and it helped the gear noise about 75%. this is the noise you have at 60 MPH under throttle. the noise was not there at lower speed, and would go away when you took your foot off the throttle. I believe it to be gear mesh noise only.
