Snow Storm? Yes. Double Leaks?!?! YES!....HELP!

Head scratcher here. Since a large snow storm just started....what perfect timing!

So I had to get to work in a hurry this AM, so I ran out 75+ the whole way to work (about 40 miles highway). Since this put me right at the fuel light, I stopped for gas. Was about to get back in and saw some drips....that's where this started.

Leak #1: puking rear diff breather tube. Before we all say "too much oil", let's point out I checked (not changed) the fluid back in JUNE.... been running around a long time since. Also, I've never had the cover off, so it's stock, didn't install ARB locker, etc etc. It's stock and this is a fluke occurance.

Leak #2: T-case. I'm assuming I'm getting the leak around the speed sensor. Since these are simple little beasts, I'm not as concerned. I'll just fill and go. It's something I can definitely give myself piece of mind by doing in an autozone parking lot.......even in work clothes.

Mine is lifted 4" with 33's, so nothing crazy. I've run over 70+ on many occasions, no problems whatsover; some rare times even 80+. The difference here is I was 75+ the entire way, most times I'm not. It's odd that I'd randomly have an issue due to heat in the drivetrain, but I won't rule that out; it seems like the only thing that I could count on causing a double whammy on a "quick" ride to work.

What do you guys think? Either way, I'm headed to a parts store to top off my fluids - that's step 1. But keep in mind we're getting a foot of snow today, so finding the root cause (or giving me piece of mind) is imperative.

Figured I'd mention that I haven't had the truck wet (no deep water) either; I know that can cause purging issues.

.........did a flush of the xfer case and rear diff and put some RTV on the speedo pinion.......thought that was the "cure".

Apparently not since it's bleeding red again today. Might be time to re-seal the SYE adapter case and replace the star washer. That looks to be todays culprit.

STILL don't have a reasonable explanation for the rear end burping up the vent. Like I said, no water, didn't fill it anytime soon, no ARB/regear.

Could of been the vent was plugged, let it build up pressure till the pressure overcame the blockage. And when it did it puked fluid along with air.

Something as simple as moisture and freezing temps could cause the valve to hang up on you.

That's kind of what I was thinking as well. I blew the vent line out with the air hose (gently) just to confirm it wasn't plugged. I hope what was in there.....isn't anymore. I haven't had any gear oil since though, so that's a good thing.

Haven't had time to get to the other leak; had to get my other truck back together so I could at least have 1 acceptable winter vehicle. But over the weekend I got underneath to see what I could see and I don't think it's the SYE adapter; I think it might be the case instead........so out she comes again. Oh well, at least I know how to do it, just sucks having to do it in the COLD! Why can't stuff break in the summer! hahahaha
