diff change question

[wikkid]

There seems to be 2 fill plugs for the diff on my 04. One has a red tag that says limited slip fluid only. After i add the 4oz addidtive, do i have to crack the plug above it for the 2 quarts. Dont remember last time messing with the bolt on top.
Thanks

the top plug is for the diff cooler so the bottom plug is the only one you need to deal with. I actually made that mistake by filling the upper one. I finally realized I had the wrong plug when it was taking more oil that I ever put in before. I had to drain it and refill. Felt like a ********.
