    Easiest mod yet ran the line up the brake line, back on top of the frame then up to the back of the front corner of the drivers side cubby. I tighten the union on the axle bout three fingers tight then another quarter turn, is that tight enough?

    Quick question. I went wheeling a week ago, and stopped in some fairly deep muddy water (getting close to my door sills) to try and practice getting out if I get stuck in deep water/mud.

    Is my diff now flooded and full of mud? Did I royally f*ck up and now need to flush my diff, or can I just add the breather mod for the future?

    Edit: Crawled around under my truck, I don't think it got that deep. I did get an underbody wash, but judging by the mud splatters on the diff, that didn't do anything, and the area around the breather is clean.

    I assume you haven't done this mod?....I would recommend cleaning it.. just cause you don't know.. there will always be that what if.. even if it didn't look like it..

    Doesn't matter if your breather was clean or not. The whole point of this mod is because the stock breather snaps closed when the diff cools quickly, and causes water to get sucked in through the oil seals. So if ANY part of the diff got wet you're at risk.

    Eh? So how does relocating the breather fix the oil seals problem?

    you put a real breather out of the water and when it cools down fast, it sucks in air instead of water

    You replaced the breather that shuts with one that doesn't, and move it higher so the diff can still breath while it cools to equalize pressure.

    Ah, I see! So Toyota probably used a breather that shuts on purpose, thinking "Ah, if the diff is submerged water won't get in!". But the oil seals then become the weak link, and water gets in anyway.

    Well, I already flushed the fluid. Didn't see anything that looked like mud or water, but it was murky and full of first-break-in shavings anyway, given the truck is still new. I'll be avoiding deep puddles until the parts needed for this mod arrive.

    It's a good thing I bought extra fluid, btw- my diff sucked up a good 3.5 quarts.

    This was the first mod I did when I had my tacoma. Bought a tundra and I'm wanting to do the same for it. Can anyone tell me if these parts will fit my tundra:

    Toyota Part numbers:90404-51026 Camary Union and 90930-03136 (Breather Union)

    Anyone do this to a tundra? I ran the one I did on the tacoma into the fuel compartment and can't do it with the tundra from what I can see. Ill have to find a good place. Any advice?
    Thanks

    Why do you have to run it up into to the gas tank fill door? Why not just tack it up in the negative space between the bed and body that you can see in step 4?
