Hot gear oil smell - found this
Coming back from hauling the TC last weekend, I thought I smelled hot gear oil. Wrote it off as no big deal given the few hundred miles of hauling. Today after hauling a single load of water, smelled it again from area between bed and cab. Got under the truck once it cooled down and found this. That's the rear of the transfer case and there's a film of oil (or grease?) sprayed on the underside of the bed. However the seal and everything around it looks dry.
Is this normal? Does the seal look okay to you guys? Is it supposed to be seated all the way up against the body of the transfer case?

Differential fluid has a stink all it's own. It's hard to mistake it. But if the transmission fluid from the transfer case is spraying on the exhaust, it could smell pretty bad.

Thanks guys. It didn't look right to me either. I've replaced u-joints on older trucks and done a good deal of wrenching but never really messed with a transfer case. Called the dealer, they said they've seen a couple like this, and she's scheduled to go in tomorrow for repair. Here's hoping the transfer case still has oil in it and isn't damaged.
Guess it pays to stay aware of your truck and keep a sharp eye, uh.. nose out. Oh and yeah, it really did smell like hot gear oil - just not as pungent and only a few wafts. Would've been real easy to ignore. If you have an F350 dually, might be a good idea to get under it and take a quick look at that seal.

It did to me just not as strong. Moral of the story, pay attention to the smell of your truck when you've exercised it. Thanks again for helping, gents.

Mine did the same thing. Get ready for a fight, kept telling me unless it was actually dripping then it wasn't a leak. Two dealers said this. Keep looking until you get a dealer that will actually do something about it. Finally found a good dealer here that was going to do something about it, but Long story short, mine stopped slinging the fluid (have verified that it is full).

Sorry to hear you had to fight to get yours addressed but thanks for sharing. I'm wondering if this is a recurring and common thing I need to keep an eye on.

Thank you. Have you towed/hauled heavy since the seal was replaced? We've hauled heavy but not abused the rig in any way. I only have ~16K miles on the truck and wouldn't expect to have a seal going out already unless there were some defect?

I'm at 110,000 miles and the underside of my truck is dry as a bone from one end to the other (knock on wood).
