I changed the oil in the front and rear differentials of my Wrangler today. It has the Trac-Loc rear and I put in Mobil 1 gear oil that says has limited slip additive. The manual says to add four ounces of limited slip additive. Do I still need to?

Drive it a bit and see if you experience any chattering when turning. If not, you are good to go, otherwise you should add only a little at a time until it stops. You can add too much so be conservative when adding.
Try it as is. If it does not bother you leave it.
No, It's already in the gear oil. Take it for a test drive and confirm.
No. It's limited slip oil. I used Mobil 1 LS oil in my 04 Silverado w/G80 locking differential. Used a Kendall limited slip oil, I think it was old stock, in a 60 something positraction about 6 or 7 years ago. No additive necessary.
