Axle Vent Mod Part 2

krh2

Administrator
I was inspired by Honeykeeper’s documentation of this mod. However, the brass 1/8" NPT x 5/16" barbed hose adapter would not thread into the hole on the axle. I did not want to “chase” the threads for fear of ruining them and not being able to use the OEM breather or the brass barbed hose adapter. I found out that Toyota part # 90404-51026 works perfectly with the threads in the axle.





Parts used:




6 ½’ of ¼” fuel line

Fram fuel filter G1DP (which came with clamps) so I didn’t have to use the hose clamps

Toyota part # 90404-51026 “union”

3 zip ties



The goods:















Remove tail light assembly (10mm) x2 after removing bolts slide fixture outwards towards back of truck.








Inside light well







Install filter and run hose down through bottom of tail light well. Then rout hose through the frame and zip tie to secure. Leave enough slack for maximum suspension extension.



























Remove stock breather (14mm)















Install new breather tube nipple (10mm)







Brass barbed hose adapter / OEM breather cap / Toyota Part # 90404-50126 hose adapter.







Video of the very basic OEM breather cap.

Why do this mod you may ask?



1- It is inexpensive (less than $25) and offers better venting than the OEM vent. I have read a couple of stories where Titan guys have gone to do this mod and when they removed the OEM breather valve they hear air escaping. That meant the axle/rear diff was under pressure signifying a faulty breather valve. That may explain the many reported axle seal failures on the Titan.



2- If you go off-roading and submerge your rear axle you could get water mixed in with your rear differential oil.



3- If you trailer a boat and have shallow launch conditions your rear axle will be submerged and have the possibility of getting water mixed in with your rear differential oil.




Shallow like this. I put a plastic bag over the vent and secured it with a rubber band. LOL







4- Another inexpensive reason to wrench on you truck. <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/003.gif' class='bbc_emoticon' alt=':smt005' />

Hmm, you didn't mention that in the instructions...when exactly do I take these multiple beer breaks? What is the best brand of beer to use? How do I know if I've used the beer correctly? How long is the install with said beer breaks?



Thanks

Hopefully my 'yota part comes in today, so that I can complete this mod. I didn't notice the tailgate assist mechanism in your pics, is yours an 04 model? I might have a harder time mounting the filter because of that. Will take a picture later.

I have an 04 but I did put in the hoppy gatre assist. Honeykeeper did a write up on the same mod and he has an 05 with gate assist. Heres a link

He didn't want to chase the threads and risk getting filings in the axle/differential housing or not being able to reuse the OEM vent which I don't think is a possibility or an issue.

I just used the tap to make sure the brass fitting was going to slip/thread in without damaging the initial thread so it really wasn't re-cutting all of the threads....but it's been awhile since I did it so his Toyota part makes the job easier if you don't want to tap the threads.

Also when a proper tap-thread-compound is used it retains most of the shavings as well as the groove in the tap. <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/004.gif' class='bbc_emoticon' alt=':bed:' />

Have you removed and inspected your OEM vent to see if it is operating properly?

Do you still have the brass threaded barb fitting and can you show us exactly what the thread difference is? <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/004.gif' class='bbc_emoticon' alt=':postwhore:' />[/quote]



I still have them both. shoot me a pm to remind me to post some close up pics.

Forgot to add, I did this mod a couple weekends ago when the 'yota part came in. Quick and easy, one of the simplest things you can do to improve your truck!
