the birfield only touches the inner axle and the brass bushing in the spindle (and the flange splines)....the 'cage' is inside the birfield....centrifugal force will spin any extra grease off the birfield
if the birfield touches anything inside the knuckle other than that brass bushing and the flange, then you are contacting non-machined surfaces and have some MAJOR problems
you'll see once you are in there....
