rare front differential oil leak

[vidvis]

Ira - you were right. Geez, I've been working on my own vehicles for 30 years and even when I go back and compare the two substances, it is still hard to tell the two fluids apart. If not for seeing the oil/liquified grease seep out from the halfshaft end cap, I would still be looking for the cause.

The halfshaft was still under warranty and has already been returned and replaced with a new one.
