In this video issue and easy way to modify the rear axle vent on the Nissan titan. After time, dirt and corrosion, The axle vent on these rear differentials do not allow enough air to move through the axle when the temperature rises. When the temperature rises so does pressure in that pressure has to go somewhere. So the weakest link is not active and see you. I have seen countless cases of people replace an axle seals due to a leak in 200 miles down the road that axle seal leaks again. I’ll do because the accident was not properly venting here at The axle vent on these rear differentials do not allow enough air to move through the axle when the temperature rises. When the temperature rises so does pressure and the pressure has to go somewhere. So the weakest link is the ask and see you. I have seen countless cases of people replacing the axle seals due to a leak in 200 miles down the road that axle seal leaks again. I’ll do because the axle vent was not properly venting air out of The differential. Below is a parts list I have made to help you do this modification quickly. All these parts can be purchased at your local auto parts store. Thank you for watching if you have any questions or comments Feel free to leave something in the conversation. Thank you

Thanks Aaron for the quality of your videos and the parts lists/details that you add. 2005 Titan - I'd replaced the driver's seal some time ago, but the passenger is now replaced this weekend thanks to a refresher course watching your video - and, while I was there, took your advice to come over to this video and have made the vent modification - having the parts list and links (some parts were not available from link, but having the part detail was easy to find another option). Made the setup easy - had everything I needed out of the gate! The donate link is handy too and has been used. Thank You!!

I just did this breather mod to my 2010 nissan titan SE and used a 1/8 BSPT to 1/4 barb fitting since I couldn't find a fitting with a bigger barb size. I hope this helps people looking for the right 1/8 BSPT (British Standard Pipe Thread (28 per inch)) fitting. Don't use 1/8 NPT bc the thread count (27 per inch) and design of the thread is different.

[@Jackmanis]

Where did you get yours? I bought one from autozone and it was a different thread pattern then the OEM valve.

Hey Arron, I enjoy your videos and know exactly what I need to do to keep my 08 Pro4x running. If you ever have a chance please do a video on the full install and removal of the alternator on a gen 1 Titan. There are not many videos on this on KZbin.

Just a heads up; the brass fitting is a 9/16. The 14mm won't work. Good tutorial! Worked a treat!

[@ryanh.2049]

I just pried off that little metal cap on the existing vent with a flat head. Then put the hose over it with a hose clamp.

How did you manage with just a flat head? Seems like the metal cap is one piece

[@jasonray2069]

Great video, but the fitting is a 10mm 1.0 not 5/16

[@douglasdever6134]

Logical location, just get the vent high enough to keep the location out of the deepest water to be in. No need to go up much higher since flooding the cabin could result in electronic getting soaked and those inside the cabin are not waterproof. Plastic fuel filters are great for that application. However, one point....clean the area where the vent is before removing. When you pulled it out some dirt fell down the side of the axle, and most likely some fell inside the hole. And if the new fitting is tapered, do not use any tape, could not tell if that new fitting was tapered or not.

[@brandonbelchersr9496]

What year titan is your mod on? I hear this thread pit will not work on a 2010! Believe the gentleman said his 2010 had to be a 9/16 threaded barb??

If your axle seals are blown go to summit and buy complete axles. They come with abs reluctor, wheel bearings and seals pressed on. Make sure you check as shorter axles fit elocker, and I believe they are $250 each however non locker Titan axles are $150 each…. Getting seals and bearings pressed will cost much more.

Great video! Im new to the titan world. Just bought a 2004 with 165k miles. I heard this is a common issue. I love the truck and want it to last me awhile so i want to do this. My question is, so the differential already has a vent, its just not enough to release all the pressure?? If so, the fitting you put in would be the same size it already had, or at least the exit would be the same size. Can you please elaborate on this concern I have. Im sorry it probably is a dumb question so be easy on me lol thanks! New subscriber!

[@shmonsterman1356]

[@jasonwadley1191]

Do you need to secure the fuel filter in the frame? Or do you just wedge it in there and hope it doesn't come loose. I purchased a 2015 Titan with only 103k miles and I love it. I am going to do this mod to the rear dif because I believe that if I take all of the necessary preventive maintenance on it then it should last a lifetime. Thanks.

I can confirm that the filter he links to in the description does vent both ways.

[@tombraun722]

Are leaking wheel seals often due to bad wheel bearings ?

[@DeathAngelHRA]

Your seals can leak from too much pressure if the axle vent is plugged or if there are metal shavings in your gear oil, that will destroy seals, which in turn will destroy the bearings and possibly the axle shaft which will of course cause metal shavings.

[@awolo06]

He explained it in the first 2 minutes of the video. When the factory breather fails air pressure builds up during operation and usually blows the seals out.

[@Taylormade2350]

Islts a common issue with these but obviously not every single one will see the issue happen.

[@Chevy-hw6lw]

However it’s possible you didn’t have issues , particularly if you don’t off road or tow much . If you use your truck for mostly small short trips. Because in those cases the rear differential doesn’t even have time to get hot enough to build up pressure. Not saying that I wouldn’t do this modification, I absolutely would.

[@azoutdoors2344]

Does this happen to Frontiers as well? I've got a 2016 Frontier Pro 4X that has oil vapor seepage out of the rear differential cover, and Nissan refuses to cover it under the power train warranty unless it leaks liquid oil. The vehicle is only four years old with 21k. miles on it.

[@sdr157]

I'd look the next time you rotate your tires, the vent is on the passenger's side of the rear axle.

[@jesseplz]

You started video saying the vent is insufficient and when pressure builds with hear it blows the seals. Your fix deals with water intrusion. Seems like two different issues?

[@andrewybanez200]

they jam because of the location causing pressure to not be able to get released, and when working properly can allow water in. so it's kind of a double fix.

[@emailjlira]

@@andrewybanez200 I did this mod, but wonder if over time the vent mod tubing will get clogged and you'd run into the same problem?

[@StraTgik805]

[@scottiefc]

Hey Aaron, right above the vent there's a hose going to the back of the rotor by the axle bearing what's that for? I was changing my axle seal bearing today and on the passenger rear rotor dust cover notice some fluid all over the bottom of the back of the rotor dust cover. I tried to smell it and couldn't tell what it was, but I think its coming from where that hose goes to.

[@90acurals]

The only stupid questions are the one you don't ask, the leak should slow down a bit as you fix the over pressure in the diff. However, it will still continue to leak, so it is best to get it fixed regardless

Aaron, I have wanted to do this for some time. I do on occasion have to drive trough fairly deep puddles. My concern is condensation being drawn into the fuel filter and water making it into the diff. Is there another type of open/solid filter that could be used? I also live in a mostly humid climate. Here is a video with the issue I mentioned. Thanks kzbin.info/www/bejne/fnvVp4GMZdmdqLM

[@AaronHinesAuto]

That is pretty interesting. yes I'm sure moisture could work its way into the diff. but placing the hose 4-5 feet off the ground and tucked out of the way has to be better then just having an open vent on the axle tube, 12'' of the ground. if you change your differential fluid every 30-40k miles like you should. i wouldn't think you would have any issues. but anything would happen i guess. i have came across this the other day, claims to block water. wheelersoffroad.com/i-25489659-differential-breather-kit-170112.html
