This is weird and no one that i've talked to has heard of it before. The rear end started leaking and I was just adding oil to it until I got another gasket and plug. When I changed it I put the whole bottle of Trans-x limited slip additive and the oil. Since then it has been making a moaning sound only when I turn. I noticed it only does it when the oil warms up like when I drive for 15 mins. or more. I also added a second bottle which seemed to help slightly but not enough. Should I try to change the oil again or would I need to rebuild it? Can anyone help me out here? Thanks

 

I know it osunds goofy, but after you add the aditive get the car warmed upp and drive some figure 8's. It allows the fluid to get into the clutches on both sides of the posi and saturate the clutches. Sometimes it helps, sometimes it doesnt.
