Maybe sludge isn't a good word to describe what I'm seeing. The gray is just as viscous as the rest, thats why I think it's some sort of addative. That and it smells almost as nasty of some addatives I've smelt in the past.

Whats odd is that it's open rear so I don't understand what or why someone would have used an addative.



That's easy to explain. sometimes people try that to quiet a noisy pinion or bearing.
