Differential Breather Mod w/pics
On my old truck, I did the full diff breather mod - all the way to the engine compartment. On my "new" 96 4Runner, I just wanted another 6-12" of stream crossing capability (top of the wheels). Here is the link for those of you who want check this install out. It took me a total of 20 minutes from start to finish.
Required "extra" parts:
1 Toyota differential breather (in addition to your stock breather)
Up to 12" of vacuum tube (get the same diameter tube as the threads on the breather) I used 7" length tube because that's all that I had.
2 squeeze-on hose clamps
1 zip tie
I hope you find the write-up informative and helpful. Its REALLY easy to do, and just might save you excess wear and tear on your rear diff. Later!

That's an interesting take on it...it should still keep you safe from the water though.
A lotta other people (myself included) route the end much higher up, but I dunno...you will probably be safe.
I'm sure they'll chime in with links to their pics. I have none...

Yeah, I would have gone with a longer tube if I had one. But for now, I will stick with the 7". I can always buy some longer tube. But this was free for me (I had all the parts sitting around in my garage)

The original pics to this thread probably dont work anymore because picturetrail cut me off.
This is an idea for the front and the rear...

I believe the transfer also has the same style breather and you may want to extend it too. But, I think it's pretty hard to get to.

For the rear diff. breather (I finally got to it last week) I just ran tubing up to the gas cap with a new union and breather from Toyota. I'd been waiting on the front, based on what I'd read on the tight space. Unless you've got real flexible tube, its going to get pinched by the tight angle it has to make, and are probably better off getting an elbow fitting so the tubing will lie flat, at least that's my thinking anyways.

Hey 96Runner,
Where did you get that yellow tubing? I would like to get some of that so I can replace mine. Nice looking picture and set up. Please let me know where the heck did you get that tubing. Thanks.

For the front diff on 1st gen's - you're stuck with modifying the stock breather. The replacement unions are too long and don't fit under the oil pan. A 90deg. union would be great, but you can't thread one in because the hole is too close to the rest of the case - union won't spin w/o hitting the case. Like was said earlier, just pop the top off of the original, attach your extending hose (& maybe some sealant to be safe) and clamp it down.
Has anyone been able to extend the transfer and tranny breathers on a 1st gen?
