Do the diff ASAP. The manual says 30k iirc, but it should be more like 15k. There's a cabin air filter. Go ahead and change that too.

Why doesn't the manual put it as a requirement? I would done it long ago!

What about the auto transmission fluid and driving belts?

MacCool

What does Nissan know about differentials...? I'd go with anonymous internet advice.

My 7A went out at 50,000 miles replaced under warranty. Nissan designed this unit to not be serviceable and claimed it was designed to last the life of the vehicle with the original fluid. The service director told me that they can't open the transmissions for repair, they can only change the fluid or replace the entire unit. The part costs $9,740, the lowest price I have seen is $8,045. Installation a couple grand more.

Nissan was astonishingly stupid and short sighted with the design and strategy regarding the transmission. The heads are the same way. When you look at it through that lens, it isn't hard to imagine maybe they are also wrong about the differentials, better to be proactive with the rear diff.

Interestingly, when I picked up the car the service director came out and launched into what sounded like a well rehearsed speech in defense of Nissan transmissions, saying that there are very, very few failures and that the 7A and the CVT are getting an undeservedly bad rap. I have read otherwise about both.

i dont understand where your sarcasm is coming from. i stated what the manual directed, was not going off some internet opinions

MacCool

Why do you think the manual doesn't state it as a requirement?

kenchan

not sure... nissan must be idiots cause the internet PROFESSIONALS state it's a MUST DO or ring blows up and shitt... lol

I suppose you haven't changed anything that I listed, since the manual didn't state as a "requirement"?

MacCool

Quoted you directly. The Internet Expert said you should change the fluid. You were distressed because the manual hadn't warned you of this. Nissan should be at least as smart as Chuck33079

I figure that the manufacturer, who is also on the hook for warranty claims, knows better. You're correct. I follow the recommendations in the manual. I see no reason to try to second guess Nissan, no matter how dirty the oil "looks".
