Diff Breather Help

[004Gunner]

I only have 1 breather hose mounted in my engine bay and was wondering if the other hose may have dropped down somewhere. Can anyone tell me if their 3rd gen has 1 or 2 breather hoses mounted to fender apron? There should be 1 for the transfer and 1 for the front diff, right?

I have two mounted next to each other. 1 Front diff, and 1 Tranny.

Where they are located?

Should be two right next to each other.

alp - If you're looking at the engine bay, it's to the right side, towards the firewall.

So far I found only one on my 1999?

I looked all over today and could still only find the 1. I didn't trace it back but I'm pretty sure the 1 was from the front diff. If it weren't for half a glacier being stuck underneath my runner I would've removed the skid plates to trace it.

Ok I just checked the '02 FSM and it definitely shows 1 breather hose for the transfer and 1 for the front diff. Now I'm wondering if this was yet another difference between the '99-'00 and '01-'02. I remember Thai discussing the 2 breather hoses from the factory and I think he had an '01 or '02.

Ahh yeah, I know for a fact that there are two on 01+. Hell you found a project for yourself, add xfer and rear diff breathers.

I would not look forward to adding a transfer breather at all, assuming that is the one I can't find. I would like some more replies from some pre '01 runners though. Come on guys, it's not that cold outside!

Just talk about Clear Corners and you will have 100,000 replies! haha

Alright, so I threw on the boots and went outside for ya. I just have one also. I never really looked for the front ones before because I've always heard the front diff/tranny/t-case breathers were all up in the engine bay high enough. Either way, I wouldn't worry about it. I've crossed too many flowing streams and mud holes to count over the past 9 years with mine and never had any water in any of my junk. I'll have to take a look and find em one of these days though, unless you do first.

breather extension

You transfer case breather has no extension:

check out this post:

Let me know if you have plans extending it...I might go and do it in the summer.

good luck

Thanks guys! :thumb3: Foureigner: I actually found the thread you linked to when I was searching this site.

I doubt I'll be doing a transfer breather extension. I really just needed to confirm that the gear oil was flowing out of the front diff breather and not from a leaking transfer breather. :thanks:
