I'm not convinced that this is right. These are very tight tolerances (on some cars more than others, possibly) and without a vent on the other side, you could have yourself a bit of an air seal happening. I don't believe they're greased from the factory (on the LCA side) and I think there's a reason for that.
The QA1 LCAs have spaces at the points of the hex (IIRC) on the torsion bar socket...unless someone knows different, I suspect that these might be there to vent extra grease.
