I used Mopar 75W-140 gear lube with the Mopar Limited Slip Adative P/T# 04318060AB. It's a 4 FL OZ bottle, used it all last change, no issues what so ever.

Dealer scam... Mine attempts to charge me $120 per diff but I always laugh. It's very simple to do this on your own. Look for one of the how-to's and start doing it yourself. I do mine 1 week after oil change or next following oil change if I didn't offroad any during that time.

Agreed, when you go the Royal Purple route, they have it in the oil.
It's my understanding the MOPAR product which I used does not contain the additive, and is a seperate little bottle that needed to be added.
Either road you go down, it's all good.

Sometimes dealers suck... Had my 09 in for an oil change... I knew the diff service was coming up, but they wanted $139.00 for REAR ONLY...
Anyone want to tell me what they are doing for a "Rear Diff service" besides changing the oil???
Needless to say, I have four quarts of Royal Purple in my garage that will have new home this weekend...
Anything need to be looked at besides fluid?
2009 23k miles (yes, I don't drive her much)
