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.

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.
