There's an "O" ring on the output shaft that is either worn or missing.
It seals inside of the slip yoke to prevent this.
You will probably have to remove the extension housing to replace it.

thanks stuart1
i have the diagrahm and its called a spline seal, dropping this extension housing is something i can do in the drive weay? looks like six bolts and a gasket, that output shaft isnt going to want to come out also, anything to whatch out for other than a big pan to catch the fluid
thanks again
