i got my Felpro gasket Permatex Blue RTV and Valvoline SYN 75-140 gear oil it says its for limited-slip

Thanks in advance and Happy Trails

Mopar didn't put a limited slip in there, there is nothing else that needs to go in there. If you're still rockin the factory diff cover, all you need is a little silicone to seal it, a gasket isn't necessary. Lubelocker gaskets look pretty good, they're reusable.

Ok even tho it says limited slip which you just said we dont have in are libertys (i dont think so but that was the only way i could get the weight i need was with it added in to it) it will not hurt anything this is a first time for me to change rear diff fluid so just want to make sure
also i did look at those lubelocker gaskets but 22 bucks for one in is $$$ yes it is reusable and since the felpro was only 4 bucks i want with that

Wow, I had no idea they cost that much. I just used silicone without a pealed gasket. That's what they put on from the factory. The OEM cover is a pos in my opinion. Once the little plastic plug is removed it doesn't seal properly. Maybe if you put a new one in after you fill it with oil it'll be ok. Thats what I plan to do if I keep this cover, mine is wet around the plug, it isn't leaking though.
