That is the type that is being discused.
If those are the type in question. And the OP has an issue with purging.
He can try this.
Loosen off the bolts.
Rotate the caps 180 deg
Tighten bolts and grease.
This will probably work.
However way to much emphasis is being put on the U Joints.
It takes a lot of miles to wear them out.
They are a bearing and like wheel bearings don't require greasing every 5000.
To do it gives a person a nice warm feeling.
Yeh I know what the book says and they are covering for the worst case scenario in really bad conditions which we just don't drive our units in.
