Wonder if any water got in there when I was at the boat launch last weekend? AMSOIL 75w140 severe gear being ordered tonight for a diff fluid change.

 

Looks just like mine. Rusted solid . I just got my axle vent kit from Cajun yesterday. Don't know how long its been like that but so far no seal leakage. Will be replacing this weekend.

 

Old news...

 

but new news for new owners.

Definitely a needed upgrade.

 

Adding the axle vent is a good mod in many ways. that 30 or so dollar upgrade will save ya a headache down the road hopefully.

 

Finally changed the axle vent using the Cajun kit yesterday. You got to do it. Its not a joke. I don't know how the axle seals did not blow out or leak but this was clogged shut. While I only have 69000 on my 05 it could have cost me a lot more not to do it. CHECK THOSE VENTS !

 

Rear diff fluid change after swapping my axle vent for breather kit:

Don't go mudding and everything will be cool.

 

Not true, don't follow this advice, even if you don't go mudding!

 

So FishinAlaska are you saying this mod is unnecessary ? Even rusted closed like mine were. If you want to climb under ever couple thousand miles and check to be free that's up to you or you can do the upgrade and forget it.

 

No, that's not what Fishn said at all. He was replying to the other poster who said you could avoid this mod if you stay out of the mud. That's complete hogwash, and this is the first mod any owner should do, hands down.

 

In my diff video in this thread I show you how bad my vent was without mudding, only after 2 years and 30000km.

 

Well, it looks like this is something I'm going to have to check into when I can. I really know nothing about this rear axle vent kit, but I got a 2013 with 30k on it and I'm willing to bed that me axle is going to be the same story as all of the previous posters. Thank you for bringing this problem up for me! I forgot all about it!

 

This is an absolute must for anyone that owns a Titan. Why flirt with disaster??

You can do it one of two ways. Buy the kit from Cajun (~$40) or do some sourcing on your own and save a few bucks. If you self-source, just be sure you get the right fitting (I ordered one from Nissan, a perfect fit) and plan on going to multiple parts stores to find a fuel filter without the check valve. I think, all told, I spent about $20-25 and a couple of hours sourcing time, plus 20min to install it.

I guess there's a third option. You could do nothing and pray it doesn't bite you, then complain about how crap Nissan is when you have to shell out for rear axle seals. But that's not smart.

This type of mod was the first thing we always did to every truck we've ever owned in my family. Used to run the lines up to a t-fitting mounted to the firewall and vent both diffs there, with a nice (chrome) Moroso valve cover breather as the vent cap. This is way easier than all that.

For the DIY inclined, you can use either Nissan part #38323-C601A and 3/16" ID tubing, or Toyota part #90404-51026 and 1/4" ID tubing (this is the fitting commonly used in the complete kits), or Toyota part # 90404-51319 and 3/8" ID tubing. Get a cheap filter - no check valve - for the open end of the tubing such as O'Reilly's Part # 7-07103 (for 1/4" ID tubing).

The threads on these fittings are 1/8 BSPT (British Standard Pipe Taper thread), NOT 1/8" NPT (as you will find in your local hardware store) and NOT M10 straight thread metric. You might be able to force a 1/8" NPT fitting in - some folks have - but I wouldn't recommend it. There is a very slight difference in thread pitch - the correct 1/8" BSPT has 28 threads per inch, and the common 1/8 NPT is 27).

The Nissan and Toyota parts should be available for around $5 at local dealers. If you have trouble starting the new fitting, you can chase the threads in the axle with a 1/8"-28 BSPT tap (Sears has them for about $7 http://www.sears.com/vermont-america...-SPM8597308225).

Easy mod - hope this helps.

 

No, I am saying do the mod regardless of what you do in your truck, this is a must, OEM vent is crap and it clogs up very easily with dust and rust from normal everyday driving.

 

BTW I had axle seals go out in my old 01 F150 and my sons 05 F150, very common in those trucks too, not sure if it is due to a bad vent or just bad design.

 

Sorry FishinAlaska. That was not the way I read it. My bad.

 

I still need to do this on my truck.

 

Cajun has the Axle vent kit in stock and ready to ship. I use the Toyota nipple which works. Shoot me a pm, call or text number is on the website Cajun Bpipes | shreveport, LA 71129.

 

Biggest hoax ever. The early seals leaking problem was supposedly fixed but either way another hole in your axle is just gonna cause more problems...

 

You would think that somebody that puts that much time and money into building a quality overland vehicle would actually know more about it, but apparently not...I would hate to buy one of your builds and have my seal fail (potentially out in the middle of nowhere) because you thought $30 worth of parts were a hoax.

 

There's one in every crowd...

 

Uhhhhhhhhhhmmmm, nobody is adding any holes to their axle...folks are just changing out the thing the factory clogs the hole with, for something which lets it vent as it should. If this were a hoax, why'd the factory vent the front axle the way we're now venting the rear axle? Either you're being obtuse on purpose, or you have no idea what you're talking about.

Feel free not to mod yours. Just keep your dadgum mouth shut about having to swap your axle seals when it happens.

 

This is what my axle vent looked like at about 25k miles, completely clogged and rusted shut, no air could go in or out. After the issue was "supposedly fixed on earlier models"

 

Wow. I missed the sight link for "tactical overland vehicles." I'd have to call you a poser if you're building so-called overland vehicles and you're not high-venting the axle vents. First time you ford a stream, you'll have water intrusion and you'll only find out a few thousand miles later. Yeah, you really know your stuff.

 

WOW This BoneTac guy is quite the clown. He has another post where he has a 1/4 ton Titan. HUMMMMMMM. I have never seen one. Mt axle vent picks were earlier in this post. Rusted completely shut.

 

Wonder if 06 Hemi is trolling us again?? Lol
