Push the front axles (CV joints) inwards as much as possible.
This disengages the seal COMPELETLY from the CV joint and leaves a gap that the grease can flow through.
By the way this is the way Dave Lenzi greases his front bearings.

It seems to me that even with the zerk you have to push the front axels inward. In that case, why not just buy a Chuck Aulger front bearing greaser from JimK and forget about drilling the knuckles?
