Other than complete replacement of the rear diff, you could switch to a TruTrak LSD differential. Problem is, you lose the E-LOCKER.
1) Nissan won't sell just the gears because their fix has been to just replace the rearends under warranty. I was wondering what was gonna happen when guys such as you, who are out of warranty, have a failure. Answer--they try screwing you into buying a complete new rear axle/diff assembly....total BSCarrot Top said:My questions are:
1) Why can't the broken gear just be replaced vs buying a new rear end?
2) Are parts (ring, pinion, spider gears) available to purchase to repair rear end by a qualified repair shop?
3) Can I keep my locking rear end after replacing broken gears?
4) Has somebody else repaired theirs? If so how much did it cost you?
5) If I have to buy an axle from the dealer how much is a fair price for the part?
6) Has anybody put an other brand/size axle into their Titan? Other then a Dana 44.
7) Is there any other options I have not thought of?
That is the same as I was told. There is no updated differential. They will just keep replacing them until your warranty runs out and then it's the owners pay. There is no fix, that why they don't sell the parts. Just a roll of the dice when the rear will fail.Carrot Top said:Here is my update from the Driveline Shop. They called Spicer regarding the OEM Locker and found out there are no changes to the original 2 spider gear model. There is no 4 spider gear model. They even told the Driveline shop that the OEM Locker is prone to failure. Nissan is replacing rearends with no better a model then the Titan had before. Based on that info I am not going to pay for another OEM Locking differentiial that will break again.
I went ahead and had them order me a Detroit TrueTrac differential. Mr rear diff is making noises now so time is of the urgency. I would recommend every Titan owner to regularly change their rear diff oil for the first signs of metal on the magnetic plug. (absolutely check it right before the warranty expires at 60,000) Then get your Titan in to Nissan for replacement. Get yours covered under warranty before it expires like mine did. It will cost me $1000 to fix with the TrueTrak.
Question for anybody who has replaced their Locker with the TrueTrak. What did you do with the electrical wiring running to the rear diff and the module attached to the rear diff. Does it just stay there or does it have to be removed from the housing?
I think you are right! When I had two new diffs start whinning at about 2k and both had dates of 10-16-06, something smelled fishey. Later I noticed others that failed after mine had replacements with that same date. The are feeding us re-runs. A friend with a 07 had his diff fail and his new diff had a date within 2 months of the date his failed. My truck is a 2wd and the problems I had was leaking wheel seals and whinning comming from the ring and pinion. I think they sent them back to factory or local shop and adjusted the r&p and sent them back out. About what I would expect.Herbpov said:Does anyone know what they do with the rearends that they take out? I'm beginning to believe that they rebiuld them and use them as replacement rearend. That's maybe why the replacement ones have a different part number. Just something to think about.
I wouldnt blame you..I couldnt wait neither till my trutrac was done being installed. I love it. Everyone loves it, you'll love it, just be carefull when its wet, itll really put you sideways in a jiffy.Carrot Top said:thclimer,
Yes, I installed the finned cover as soon as it was available in 2005. After reading all the posts on rear end problems I didn't want to take any chances. I also did my first rear diff oil change after break in at 1200 miles. The original oil was so black and burnt smelling you would have thought that it was in there for 50,000 miles! At that time I went with Mobile 1 75-90wt synthetic. After I got the finned cover I switched to Mobil 1 75-140 wt synthetic per Nissans recommentation. I have regularly changed my rear diff oil every 20,000 miles. Always Mobile 1 since the original break in oil.
I think I took too good of care of my rear diff. If I hadn't been so paranoid about taking care of the rear diff I think it would have failed earlier under warranty. Saving me the $1,000 to pay to fix it now out of warranty. I think all the locking diffs are a bad design and are prone to failure.
I hope the TrueTrak will last the life of the truck. Can't wait to get it back from the shop.
