If the ring & pinion are ok you could have a TruTrac installed and it would be much stronger than the stock rear end and half the price.

I agree for the money and peace of mind get a true trac installad. If that doesn't do it for you then PM me and I have a fresh stock carrier, and bearings on it still, finned cover and bolts for cover out of my 06 I will sell for 200 bucks, and all plus shipping to ya. I had true trac installed. This carrier is less than 16 K on it and just came out this weekend.

My understanding is that because of the nature of these rearends, and the fact that the dealerships are simply replacing the entire unit 'wholesale' when a failure occurs, that Nissan doesn't sell just piece parts for the rear ends. They carry axle seals and bearings, but not any of the other parts, like the spider gears, ring gear, etc.
Yes just the spidergears, I shered off 3 teeth. ring and pinion is fine.
yes sir the rear

oh, i meant what caused the spider gear to break?
typically on the rears i've serviced :rofl: it was the thrust washers breaking down allowing the spider gear to slip out of place.
then a driver must have dumped his clutch once and broke where the pinion bearing mounted to the housing... that ended up breaking the ring and pinion.

The Rears in the early Titans gave them a bad reputation (along with the brake shudder issues, both now solved). Spider gears would break, sometimes breaking the ring and pinion afterwards. R&P was not the weak spot. Nissan only replaces entire axle assembly. No Aftermarket parts available, except the Truetrac. in your situation, Truetrac would be best. Another newer model rear like from an 06 would be a good alternative, but still entails labor for the install. Nissan had an extended warranty on this, but I don't know if this is still in efffect or applies to yours, based on when you bought.
I also have an 06 Rear in the shed, should you wish to purchase it. but I highly recommend the Truetrac, for about $550 or so, plus Install. it is virtually bullet proof. I love having it back there, never worry about it failing.

I took a look at mine since it was just there in the box and just came out, the spiders look fine, and the carrier isn't a bad unit less being limited slip or posi unit, then again it is very clean with less than 16K on it. The true trac is by far a beefier unit in my opinion, I wasn't necessarily afraid of my 06 rear, but I will have around 7K pounds towing back there in the near future and I didn't want a traction issue more than anything in a campground somewhere. That was really a more of a concern for me but I still think the carrier I took out would have done the job. I had a late 06 truck, and I would have felt safe with just a Mag Hytec cover on the old carrier, for additional oil capacity for keeping the heat down. The limited slip was more of a concern than the strength of the old one, I have a 2WD so I don't spend time out in the woods with it and such, but it is nice to know it is there, there is a peace of mind with it now, knowing it will be tough to tear a rear out of it now. Once again, if you insist on saving money, I will sell it with the finned cover for two $100 bills and shipping.

Fact of the matter is not selling something you don't need, but rather the supply of only piece parts to a Titan rear end is NON-Existant. IF you got three teeth of spiders broke, there is a high likely hood of ring or pinion damage. Not sure if you have ever seen that kind of damage before but telling him he is being told to buy stuff he doesn't need is not the answer. It is a simple fact, you cannot buy the carrier, nor spider gears, nor ring and pinions from Nissan, that is a plain and simple fact. So you have a few options, pieces from junkyards, not easy either, not many parts there yet, truck is still only approx 5 years old in production. Scenario two is find someone that has replace theirs and knows it is good carrier wise if ring and pinion is good. If ring and pinion are not good, hope you can find a complete rear either junk yard or third party individual that has one, of course only 06 and later till 08 cuz that won't fit due to different axle diameters I believe. And again piece parts for this do not exist. So really, I don't think anybody is trying to sell him something he doesn't need, he is merely stating less the aftermarket, in which there is still only on option, the only way is junkyard or new from factory. That's the deal PERIOD. I'd really like to see him find just three spiders, it's a very unlikely scenario. Since you don't know why the spider broke, it appears you are not very well versed in a Nissan Dana Rear end, or you don't read much here. It is substandard metal used in early rears that is causing issues, most rears if they had a ring and pinion problem it was due to after effect from the spiders. I don't know of any ring and pinion failures, but I have seen first hand from my bro-in-laws 04 his failure of his spiders.

Typically speaking you did not refer to a specific rear end in which the thrust washers were breaking down, and was that a Nissan Titan Dana rear end or just rear ends in general, and dumping a clutch in a Titan would be an impossible feat to start with. There are no production Titans with a standard transmission ever made. So to compare another rear end to the Titan Dana is not correct unless you have inspected one. Nissan does not sell parts for one so I fail to see how you could have gotten parts, Dana will not sell them since it is a Nissan spec'd rear and is proprietary. Therefore I can only conclude with no third party support or manufacturers support other than complete rear ends that your comment of replacements earlier was not on a Nissan Titan rear end. So then that possible explanation is not on this rear end and is pure speculation without using a Dana from a Titan for analysis.

I kept the old rear-end when we put the TrueTrac in. Both spider gears are missing teeth. My tec. looked at the spiders and said the heat treatment was gone/absent and that probably caused the failure.
I'll take some pics. of the spiders, ring and pinion.

titanblue, You mentioned that Nissan had an extended warranty on that, do you know any details on that? Was it past the 5yr/60k?

No, I don't have any solid info. But I recall a few people got the axle replaced when slightly past Warranty. Say 65-70K.
I put a TrueTrac in mine around 20k, but both axle seals leaked around 55K, and when the second seal was being replaced, the dealer said the fluid was dirty. So, they gave me an 08 Axle Assembly for fear of damage inside the Diff. Easy Warranty work for them too, I think. Something to do. Nice to have new, if better, but I lost my TT. That was disappointing to say the least. I wish they had been willing to investigate the wear, and just change the fluid, but that isn't what dealers are all about. My new Axle has a 12mo./12K Warranty, so good to about 67K miles. I just passed 60K yesterday.

I just destroyed the spider gears in my 05 Nissan titan and tore it all down and now I can't seem to find parts anywhere. I have narrowed it down and am almost positive it has the 3.357 gears but can't seem to find the spider gears and two bearings for the differential!!! Any help or suggestions would be greatly appreciated
