Leak?

As I was running the harness for my locker bypass, I noticed some moisture on the passenger side. 2012 PW ~46k miles.
Any ideas? I am no mechanic

Looks like your axle seal is on it's way out... orrr your diff fluid is so diluted with water it's leaking past the seal lol. Not sure if you drive through deep water or not. I'm leaning more towards axle seal.

From the pic I'd have to say axle seal as well, does it smell like gear oil and feel viscous? Seems odd having a seal failure on a relatively low mileage newer truck. Need more info

Axle seal. Keep an eye on your lube level. Mine used to do that, then it quite. Don't know why.

Haha. I doubt it is watered down diff fluid. I have changed the fluid within the last year and a half. Have not been in deep water since. If it is the axle seal, how big of a PIA is it to fix?

It did smell like gear oil. I made sure because it rained last night. Driver side is dry

Unfortunately you have to pull the carrier to replace the inner seal. Not that hard but if you're not mechanically inclined mAy want to pay to have it done. Maybe yours will heal itself like RustyPW's, like the man said, keep an eye on the level

Its because the fluid is now low from leaking

Yea, it's full of water now from Rausch Creek.

Worst possibility is bent axle. Ask how I know. Look at the side of housing. Is it all dry there?

Both my front and rear pinion seals with leak from time to time, just enough to wet the housing. Then it might not do it again for months. Fluid level is fine, just seeping every now and then. I'd make sure the level was good and no water and just keep an eye on it. Mine began this when I changed the factory gear oil to Amsoil Heavy Duty Synthetic. I've "heard" the synthetic oil molecules are uniform and smaller and will get past seals more easily.

I've read the same thing too, about some synthetic lubes.

Same here. Since the switch to Amsoil, my pinions weep from time to time. Plus, I over fill them too, so that's another cause, I'm sure.
