My LSD is definitely grabby when turning forward and noisy if turning in reverse. Lube change a must this week. GM, Amsol or Royal Purple?

All three are good, just make sure to add the friction modifier if it is not included in the lube of your choice.

I recommend Royal Purple. It also comes with the Friction Modifier already added. When I had this issue early this past summer, I reviewed a bunch of posts here and most (if not all) had very good success with the RP product.
I tried it on my Solstice and all the noises went away on my rear diff.

Very happy with the Royal Purple product.

Ive always used Valvoline synthetic. Can get it pretty much anywhere around here. The specialty brands, not so much. Never had any issues/noise with the rear diff.

I guess we all have our preferences, in my case I went with the new GM revised oil and additive.

I used the Amsoil diff fluid and friction modifier, over 20k miles back. No issues of any kind, so far, but then, I never had any before the change. I just changed oil in transmission and diff, so it was all synthetic (if it wasn't before).

Probably a good way to go, although I've wondered about Redline oils.

Mobil1 and add a little friction modifier although it has it already.

I have the Final Solution to all your problems here:

Swap my open diff with your LSD and boom, no more annoying grabby LSD and no more dealing with friction modifiers :D
Why didn't I think of that?

Hello,

I used Red Line in my car's manual transmission and differential. I think it helped shifting in cold weather when the transmission is cold. Other than that it didn't either cure or cause any problems.
