So I just got my truck from the driveline shop with a nice new shiny front diff that was only 1900. I'm now worried I'll blow my rear diff. The truck is an 04 with 122k and I've only had the truck since spring. I don't know the history of the diff and I assume with the amount of miles it has been replaced at some point in time. I'm not a gear head at all I might as well be a blonde when it comes to vehicles so please bear with me. When I was driving the truck when the front diff went I stopped on some ice and spun the tires to see if my fronts were spinning. I noticed I left a patches with both rear wheels. As far as I know don't most rear wheel drive vehicles come standard with just an open diff or a one wheel peeler? So I'm now assuming I have either a posi. or some type of locker. Did the titan come stock with this or was it an upgrade? Or has someone updated it?

Both tires can be easily spun on ice or snow, so that is not an indication of a locker. Also, 122K miles is not a lot, and most people should never have to replace their diffs. Now, if you can leave tire marks with both wheels on dry pavement, that would be an indication of a locker.

Adding to what what said above, I can sometimes leave tire marks on pavement from both tires when doing a burnout. I have the e-locker but it was unlocked at the time.
The only locker that came with the Titan is the e-locker. If you don't have a button on the dash then you don't have the e-locker. The off-road package had the e-locker in it.

122k is not a lot but scrolling the site I read of tons and tons of rear diff failures in the 50-70 range. I don't see anyone reporting a diff failure at 100+. I really don't want to abuse the truck by leaving rubber on the asphalt. Is there any other way of finding out what I have without cracking open the pumpkin and posting a picture of what I have. I'm also going to be ordering the breather mod kit.

Very true why worry about something that isn't broke yet. I'd just like to know what I have. I was in the market for a truck and wanted something different and the titan looks awesome. I didn't do enough research before buying to ask the right questions. After joining the site and having problems I have fears of the other common problems. But hey seems after replacing the rear diff and exhaust manifolds I'll have a bullet proof truck for years.
This is wisdom incarnate. If it's not giving you any signs of failure (noise, leaks, vibration) you should just drive like you normally would and you will be fine. Of course, if "like you normally would" includes thrashing the living daylights out of the truck, maybe you should consider an upgrade to avoid lunching the whole thing at a bad time. But it doesn't sound like that's the kind of driving you're doing.

Really only worry about the seals failing, but you can prevent failure on that by contacting Cajun and getting the diff vent mod.

I don't abuse the truck on the pavement. I live up in the bush on a rough dirt road. There's always pot holes mud and gravel with some hills. 4x4 is needed to get home in the winter. Spring time there's washouts and it feels like I'm mud bogging to get home. I always do lots of fishing in the summer at remote lakes. My truck is covered in scratches from branches.

exactly why to do the vent mod. All it takes is for the oem vent to get covered with mud for it to fail and potentially leading to pressure buildup and then your seals may fail.

Just sent Cajun an email to purchase the kit. in the meantime while I wait for the kit should I go try and pop the little and clean it out?

I went outside and checked out my rear axle. I see some fluid leaking and I was able to give it a quarter turn tighter. Is there a rubber seal it that's goIng? I also see where the vent is the previous owner did some kinda home vent job on it. I should probably still buy the axle vent kit from Cajun so I'm able to go in through some water eh?

The vent will be fine in water, that vent is a check valve of sorts, that is actually why they fail when the get dirt build up, and are designed to, but do not always, let stuff flow in one direction.

thats the original diff from 2004. it has the steel cover and holds less fluid than all the others.
def do vent mod. the leak is not really a leak its just where someone filled it and never cleaned it off. dont overtighten the plug . u can take it out and teflon tape it if it is leaking for good diff fluid see the link below
