My "rear end" got toasted in the Titan today .. I guess it is a problem in the 05's... fuck, I am going to have to be without the truck for awhile.. Good thing I got the extended 100,000 mile warrantee!!

Degsy, I guess I cant drop the duc off for awhile

What's happening to the Titans exactly? Are they leaking oil from the differential or is it shoddy components from Nissan?

The 04's and early o5's had an issue with the rear diffs. It was not a nissan part, I think it is Dana. Its covered under warranty and beyond, nissan replaces it free.

I dont now anything about the mechanics, but I think the gear is getting chopped up or something. It cannot handle the torque??

I can't be certain, but I dont believe there have been cases on late model 05, or any 06 or 07. I also understand it to only havebeen an issue on a small number of the 04's and early 05's. This info is based on info from various Titan forums.

When you install the shaft through the rear diff, you have to set drag on the bearings (about 15 lb/i I think) AFTER you tighten the holding nut to over 200lb/ft torque. If they screwed up this little bit of install magic (wrong torque, not enough drag), the failures will come thick and fast. Dana rear ends will handle 3 times the torque that truck can produce...if installed correctly.

Don't blame Dana, their stuff is top notch. I bet the replacement parts are Dana too. Nissan won't make any diffs that big in house.

My bet? Snobby newbie truck owners towing in overdrive in their leather-clad, Eddie Bauer, dvd player, nav system toy trucks from Nissan. (sorry Manny and Evan, just ball-bustin'...LOL)

My Dodge has 110K on it and hardly a problem yet. One set of brake pads, one set of tires and an alternator.

Yes, Dana is top notch, and the replacement parts are Dana, but its not the same part. It was re-designed and the ones from 04 are no longer in production. Pretty sure its a well established issue that it was a dana part that caused the problem, but i really dont know what it was or why.
