A reasonable solution, but installation and purging of the air are CRITICAL.

If just installed with the line and fitting full of air and then a grease gun applied, you can blow the grease seals as all that air and then grease blow through the bearings.

Just fill both line and fitting with grease before installing and remember just a small volume of grease is needed when lubing. This is NOT like greasing king pins!
