Leaking rear grease
There is a valve on the left rear end that seems to serve as a connect valve for the rear steel brake lines and a breather for the rear end. I notice fluid leaking from it at the cap onto the rear and it smells like rear-end grease, not brake fluid. I cleaned the cap off last week and it does move freely up and down. I have heard rear end grease will leak out if the breather cap is not functioning right, but not sure what the leak is being caused by. I did not pull out the drain plug to check level yet.
Any suggestions and should I be concerned?

Normally there will be a greasy stain around the cap due to oil vapor escaping. How much of a leak do you have? Is it dripping constantly?
Have you checked the lube level in the differential?
Have you driven into high water recently?

I just got the truck, so I do not know how the PO drove it. It takes about a week of driving to show up on the axle. It is a decent amount to cause a drip off the axle. Guess I will monitor it for a while and check the level.
