2)4X4
3)OFFROAD PK
4)yes
5)Miles at 1st failure 8000, second 17,000
6) 2 fails
7)Yes
8)6000
9)Yes
10)yes four times

I have a six inch lift and 35 inch tires, both failures happened with the life, both failures I used the locker, the first failure I pulled a trailer, the second I didn't. So far I have not touched the locker, and it's only been 8000 miles. This sucks, my dealer told me they wouldn't fix it if it happened again.

Now that I am catching up on the posts, the dealer that changed out my first rear diff told me the same thing. It was the "spider gear" that completely blew apart. I too have noticed a differance in shifting. I took the truck in last week to have them document the fact that i felt like the rear end was going to go again. It is getting loose. Well it feels kind of like when my u-joints went out in my old Toyota. Give it gas and it takes a second for it to catch. Go down hill so your engine is in compression and the same thing. Especialy around 40mph. Here is a test for all the guys that have a new rear end to try. While on the freeway set your crusie control to 70-75mph. Be on level ground and then hit the cancel button. Anyone else notice something not quite right? My truck makes a nice clunk and the truck jumps. Not sure if this has anything to do with the rear diff but it sure can't help, escpecially while towing.
I want Nissan to give us some straight answers! Everytime my truck goes in to the dealer I keep thinking they are messing with it in some way or another to try and fix this with out me knowing what they are doing.

Electronic Control Unit, I think. The engine and transmission are computer controlled.

Has anybody using the $22 helper springs had a differential failure? I was wondering if axle wrap / wheel hop was a contributing factor. I have had the helper springs on for a long time and they seem to substantially eliminate the axle wrap / wheel hop I was having when I first got the truck. In this same vein, if you are taking sharp corners while accelerating heavy and you hear the tires chirping, this is likely the result of wheel hop, and is very hard on the differential.

Also, what about the Armada? Any rear differential failures? Does IRS make a difference?

Posts: 236 Replaced rear end "sloppy"

--------------------------------------------------------------------------------

I had my rear diff replaced at 9400 miles and now at 15,200 I have noticed something has changed. When I am driving and if I let off the gas and then reapply the gas, there seems to be some slop before catching. Also when shifting from park to reverse, the clunk has become much more loud and can be felt. The last time I was at the dealership I mentioned the "clunk" to the manager. He was the one who replaced the first one for me. He stated that this "clunk" is normal and it is just breaking in. Is this true? I am not one who is harsh on my truck, however the noise seemed to be louder after a 2,500 mile road trip. I have not bothered checking the fluid since the whole thing was replaced only 6000 miles ago with sytn. and nissan recommends a 30,000 mile change. I guess im just looking for some advice on this since the rear end does not seem as smooth as it once was.
Thanks

They talk to each other when they think I cannot hear them. And yes, they are out to get us.

To answere your question P's Titan I live in Nampa Idaho, and no Tom I only wish I lived in HI. My dealer is Nissan Bronco M.
I have a six inch suspension lift Pheobisis on my titan, it looks like something out of hell, I get compliments all the time on how good it looks. I have 35 inch mud terrain tires and 18" a#s kicking wheels.

Both my failures my titan was replaced with a 2005 rear end. That tells me that they tried to fix the problem knowing 2004 was a problem. Little do they know that it is in the new trucks also.

My partner has the same truck. The only thing that has gone bad with it is the brake problem, which he had taken in about four times. I would keep my truck if there was a different rear end to put in it. A Dana like Tom said.

Armando,soon there will be another rear diff-matching ft gearsets too I hope.
The multiple failures of some owners are the only fly in the"bad gears-luck of the draw" explanation.If some (1/200 ,0.5%) of the spider gears in some lots are bad,but the vast majority-99.5%-are good ,then how in the world do we explain that some owners have multiple failures?The chances that they would get bad gears 5 times is 1/200x1/200x1/200x1/200x1/200= 1/16x10,000,000,000- 1 chance in 160 billion-no chance really.
Now we could write them off as "BAD OWNERS-" and the single failure guys as winners of the 1/200 unlucky lottery.It sure would be nice to have one explanation for the single failures and the multiple failures and the "why 4x4's" are over represented..Maybe they are over represented on this forum-maybe they are used harder?They are ~200 lbs heavier-4%-sure doesn't seem like much extra weight,but maybe it could be enough to tilt things a bit??
I'm certain the Nissan already has an answer or answers-they have many hundreds of failures to study.
We will know if they fixed it soon enough-If we have 8-10 2006 failures at this time next year(same number of 2005's we have now) we will know that the problem wasn't fixed.If we have very few-3 maybe-then it was fixed.
Obviously I'm just thinking-guessing- out loud.I don't have any particular feel for diffs-but they very,very,rarely fail at 10,000 miles-I'm certain of that.Charlie
PS Anyone with a particular interest in statistics is welcome to pump these numbers thru and give us a statistically significant number for 2006.You will need to make some guesses-how many 2004-2005-2006 trucks we have here etc.Lotta bias-we are probably being sought out etc.
