I have read about some of the rear-end problems, but here is a question.

I had my oil changed at Jiffy Lube, and the guy said that my rear diff fluid level was okay, but that the fluid was foamy and had "completely broken down."

I took it to the dealer, who looked at it and said it was fine, and that it was "special fluid" that was supposed to be that way.  He then told me that Jiffy-Lube guy was probably an idiot.

After reading about some of the rear diff problems and the new differential fluid, should I go ahead and change this on my own? 

I fear that the dealer is just blowing me off and I don't want any future rear end problems.

What do you think?

The question I had was really not about Jiffy Lube, but about whether or not I should just go ahead and change the rear diff oil if the dealer won't do it.

Nissan now recommends a Synthetic for the rear differential on all Titans, Armadas, and the Infinity FX56.  The best you can get, in my opinion, is Amsoil Severe Gear Oil 75w/90.  You can get it very reasonable on my site at www.environmentalassociates.biz.  It is good for practically the life of your truck and it's backed by a guarantee from Amsoil.

That is what Nissan put in mine.
