ARB compressor spewing fluid....?

My ARB compressor starting spewing fluid this weekend while I was out. What does that mean? How do I make it stop? It still worked fine and locked up and released like normal, but there was grease underneath it, and since its mounted in teh cargo area it stinks....
Any and all help is appreciated.

sounds like the seals in the diff are bad. Take of the line at the diff and see if gear oil is in the line.

I am sure there is grease in the line. When you say the seals in the dif are bad, are you talking about the O rings in the ARB itself? If so, I just replaced them last year. There is no way they would be bad already.
