    The only problem I see with this is that beer is optional. Come on now.

    Your choice, but I wouldn't. You don't need to be 4 wheeling to run through lots of water.

    Im changing out my rear diff fluid so i figured do this mod while im under the truck. Instead of getting 1/4 fuel line i got 1/4 clear plastic line, looks bout half as thick. My question will that be take the heat and pressure coming out of the rear or is it just going to melt?

    :notsure: I'd go get some fuel line. It's not that $$ and I wouldn't want to take the chance of it melting or getting torn up...

    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..

    Remove and Replace. Not worth taking a chance.

    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.
