Do they not need 'splash' onto the upper pin for lube ?
As they don't have CV joints as such, but Tracta Joints up to '53 ? I fink ... o_O

Mines an early series 2 and does not have the rialko set up just a large spring and a cone, but yes they are always nicely covered in grease, not been any issues at all in over 5 years.
Im not really sure how the drive shaft u/js get their lube as they still have the standard rubber u/j seals fitted to everyday props, so no oil or grease can get in there.
