I have a 2016 viking vi... I thought my middle carrier bearing went out again, so I to the inside out to change it but its tight and still looks good. But there was a grey greasy film all over the front of the tranny where the shaft hooks to the tranny. No smell, just a lite grey oily film. Motor oil looks good and full. Getting g ready to change the belt and add a clutch kit. Has anybody else had this grey greasy film before?
