Gentlemen,
I have installed extended zerk fittings to the top of my sealed upper rear ball joints and cannot get any grease through the bottom side of the ball joint. I have removed the zerks and I am getting grease all the way through the extension and into the top of the joints, but there is no grease coming through the bottom side of joint. The zerk fittings only penetrate the thin top cover of the ball joint. I do not have the rubber boots installed yet. The ball joint is not mounted in the car as I am modifying it on the bench. The grease that I am using is Lucas Red-N-Tacky grease.
What am I doing wrong?
Thanks!
