OK< what rear axle can I get! (again)

[Denee007]

I go from one problem to another despite fixing them, which is good!

I took the truck around the neighborhood to make sure it was running ok after finding I had a couple bad "new" wires! While driving around the neighborhood, I felt/heard a subtle grumble, or growl. I turned off my AC, and just coasted in neutral.
Got it back home, jacked up the rear, and ran it again. The rumble is definitely coming from the rear end! Also the new yoke that I put in with a new seal is spraying 90wt all over the place sliinging from the yoke/driveshaft!
I honestly don't remember why I didn't hear this before! I thought the axle was OK! I didn't complete the parking brake cables until I was sure the rear end was OK, that's why I went and got the new wheels too.

So, back to the drawing board! should have gone by my poor instincts and bought another rear axle.
What axle will go in my truck? Sylvester, a guy that I know has a Ford rear axle out of a truck, has about a 100k on it. But what other options are available?
