Dana's Response about failures

[Sftail1990]

Personally the whole response in my opinion was hogwash. This issue has been happening for almost 3 years now. This whole paragraph was lets say shady:

2) Why are there axle assembly failures?

- Each model year has its own issues as there are small design changes, sometimes none between them. Your model year is 2005 for both trucks, I will concentrate on this. You should have the aluminum cover plates on both your axles, which goes directly with the 75W-140 synthetic gear lube implementation, both improving axle sump temperatures and providing a better cover seal. The steel plates had some cover leak issues. Also, from November 2005 and prior, there are some issues with noisy or differential failures (axle assembly internals - include diff case assembly & gearset). Basically, if you have a catastrophic failure, you do need a new axle assembly as the cause is more than likely a carrier housing issue we have found. I suggest getting a post November 2005 axle build date as a replacement, as the issue was fixed then. I have seen a few standard/open differentials break from overload, that is the only other catastrophic issue I have seen. I can not honestly answer what the cause was for overload conditions are, as I am not the driver, I would like to know under what conditions they failed first-hand. As I stated before, wheel seal leaks are still an issue in model year 2005 as well.

This part is extremely full of the BS : I will concentrate on this. You should have the aluminum cover plates on both your axles, which goes directly with the 75W-140 synthetic gear lube implementation, both improving axle sump temperatures and providing a better cover seal. The steel plates had some cover leak issues.

It had nothing to do with better cover seals or any of that, the oil was cooking the paint off the covers for goodness sake. It was nothing to do with seals there at the cover, he also never addresses that silly little thing they call a vent on the axle housing, what a joke it is. Also never said anything about the substandard metal in the spider gears.

This whole rear end issue is a joke and Nissan should hope that it doesn't happen to my 06, it should "supposedly" have all the fixes right? I personally can't see why a class action attorney hasn't been all over this one. Bro in law bought an 04 LE 4x4 supposedly "certified" by Nissan, with all the service records. Even had the rear fluid changed shortly before he bought it. Two months later .......rear end bye bye........... they say they found metal in the rear. Later they said they found water in the fluid too, I asked them well how could that happen, you guys changed it last. They always act like you had to do something to cause this, unlike the real cause that they have a crappy design and materials in the rear.

I have an 06 with 34k on it and I literally just picked it up an hour ago from having a complete front diff replacement (under warranty). However, the rear is still popping. I had them change the rear diff oil and they said everything is ok. I'm just not sure what the heck it is.

I have a Titan 4x4 LE loaded, just went over 60,000 mile warrenty. I baby my truck, the heaviest thing i carry in it is my 185 lb. body. I dont want to hear" we are working on this problem and you can buy a new an improved model" Nissan is pissing me off! I will not buy a nissan ever again! I will tell everybody that asks me about my truck its a peice of crap! in my business i come across alot of people that ask questions about my truck, and told them its the best truck ive ever had. Now i feel bad that i put those people that purchased a Titan in this position. If nissan or dana doesnt fix the problem for free- they can both go to hell
Sorry had to vent

Not to beat a dead horse, but I was just taking a gander at the tundra forums.(not that I would ever buy one) A couple of guys there were saying that the diff fluid levels on the titans came really low from the factory. Thus, probably causing overheating and combined with poor ventilation caused the leaky seals and pumpkin explosions.

I will still buy a titan but does anyone know of what I am talking about?

Do some more research. The cooking off of paint had was not with the synthetic diff lube. It also occurred in 04 where Nissan issued a TSB stating that some diffs had been underfilled during assembly. Low fluid will cause enough heat to cook paint of the cover.
