Had a shop take the cover off the rear diff on my 2006 4WD Titan to diagnose a whine/grinding noise.

Confirmed as spider gear issues, Ring and Pinion are fine.

Is this the TrueTrac I want?

I will also be replacing carrier bearings and races, as well as servicing axle seals since we're in there.

Just want confirmation on the part above. Thanks!

It says '93-'05, which is confusing, but its the right part number and mentions the 32 splines.

That's it.

That install kit looks like it has everything for a complete rebuild except axle seals & bearings. The axle bearings are Timken Set 10 and include the bearing, race, and retainer. You can buy Nissan axle seals or National makes a less expensive seal.

Do you have the factory e-locker? If you do, their are a couple of other things you need to do.

 

[El Equis]

Nope, no e-locker, so not as involved as it could be.

In hearing about how the TrueTrac performs, I may feel like I have a locker after installation.

For driving on the streets, TrueTrac is ideal. It works at any speed, in any gear, 4WD and 2WD, is automatic and mechanical in its operation, requiring no user intervention. As an added bonus, Nissan's active brake limited slip ABLS, which is quite lame by itself, assists the TrueTrac in engaging on zero traction surfaces, such as glare ice. It really is quite nice, and I'm sure you will be delighted.

As far as install, I would have the installer back out the TrueTrac bolts and retorque them with red loctite 272. There were a few instances where they have backed out after install, which may have been from a problem at the factory. A couple of people have replaced the factory bolts with bolts drilled for safety wire. Anyway, you can't mess with the bolts after install, so the time to do it would be before install.

The details on the torq spec and sequence are in this thread:

Note: loctite 272 is the higher temperature version

I was all set to go - I thought. The shop that inspected the differential seemed willing to do the work (install TrueTrac, replace all bearings, seals, and races, service axle seals) but today they tell me "we can't get these parts - Nissan will only sell the whole differential, carrier and all, or sell whole axle assemblies - $2K plus.

So how do I find a shop that trusts the parts I bring in? I told the guy I am just copying what other Titan owners have done with success, I took the damn PDF off this site that lists part numbers and they won't use them since they aren't Nissan parts and can't warranty their work. Kind of ridiculous.

Why would I use the Timken Set 10 axle bearings and not the ones from Nissan? It's 2 X $23 instead of 2 x $59, so I'd like to use the Timken for sure if the quality is comparable. I think I need a Nissan Axle Seal part number....

I am going to get every damn part needed and find a shop that will put them on. Hopefully I don't have to shop around - I guess I should find a place that specializes in drivetrain work.

My dealer used Timken when my axle seals / bearings were replaced under warranty. All of the parts are available aftermarket except the ring & pinion.

Here is the Nissan axle seal, you would need two of them.

They probably wanted to rape you on the parts. Call around to transmission, 4wd, differential shops and tell them upfront that you are supplying the parts and want a bid on the labor.

Do any of you know if this Detroit Truetrac Posi Nissan Titan 913A582 will also fit a 2011 Titan? I am looking for a solution to the terrible open diff and ABLS but the posts of bolts backing out is giving me second thoughts. I plan to drive this truck 20k miles per year and don't want to stress about the diff.

Thanks!
