I'm not a diff expert, maybe Bfit, SR Performance guys.
BUT!
I believe they are Limited Slip Diffs, and require a GM spec oil + an ounce or 2 of a special additive.
I'm sure someone with a better understanding will chine in......

Thanks that’s all very helpful. I looked at an ac delco
product and additive and it needs to come from the states, which takes some time.
Cheers
