Diff Breather Mod for Dummies (Pics)

Neubs · 10-02-2008, 08:38 PM

I did the diff breather mod today and figured I would post a quick "how to" for anyone who is considering doing it. It is a simple quick mod.

Everything you need:
1. Toyota Part numbers:90404-51026 Camary Union and 90930-03136 (Breather Union)
2. Drill
3. 3/8" drill bit
4. Teflon tape
5. 6' of 1/4" fuel line
6. Screwdriver (flat head)
7. 14mm and 10mm wrenches
8. Hose clamps
9. Zip-ties
10. Wirecutters or razor knife
11. Can of Skoal
12. Ice cold beer (optional)

Step 1: Take old breather out using 14mm wrench

Step 2: Wrap new fitting with teflon tape.

Step 3: Install new fitting/union using a 10mm wrench.

Step 4:Remove cubby to gain access to fuel filler (Pull up and out)

Step 5: Drill mounting location for new breather.

Drill bit poking through:

Step 6: Install new breather.

A look from the inside.

Step 7: Attach the new fuel line and tighten clamp (using a little dish soap will aid in sliding the line on the new breather). I ran the line parallel with the filler neck and drown the frame rail not out the bed pocket as pictured)

Step 8: Run the 1/4" fuel line and use zip ties to secure it.

Step 8: Install and tighten final clamp and be sure to leave enough line for axle movement.

Step 9: Re-install bed pocket and you are done! Enjoy a cold beer.

Thanks, I know this has been covered before, but I just wanted to post something that will instill confidence in those wanting to do this but were wary of their mechanical abilities. I know pics help a lot so I tried to document the whole thing the best I could.

with the stock location of the differential breather there is a risk of getting water into your axle housing if you traverse deep water. By moving the breather up out of the way you reduce the chances.

great writeup for the caveman in all of us. Thanks

Agent475 · 10-03-2008, 08:01 AM

Did you get these parts from a local dealer? "90404-51026 Camary Union and 90930-03136 (Breather Union)"

Is there anything that will substitute? I HATE dealerships at this point...

slimcubby · 10-03-2008, 08:55 AM

Hmm I had no idea about what this was until I watched the video... My question is... if I do only light offroading and never go into deep water since I am not 4x4 is it something that I should still maybe do? Keep in mind I live in So Cal and get hardly any rain as wel...

(i may have answered my own question but want your opinion please)

I ordered mine from TRDparts4U. Seemed a little cheaper, and what I paid in shipping I saved in gas/time. Had everything in just a few days.

Yeah, I called the local dealer and had the parts the next morning for $10. Check your dealer's website, they often have coupons that will save you some coin. Hope this helps.

They actually referred me via email to: www.toyotapartsales.com for the parts.
