I wanted to pump some grease into the ball joint and tie rods with my grease gun but found what looked to me like years of old grease and dirt mixed in next to the boots and all around the zirk fittings. I spent well over an hour chipping the old stuff off and making sure none if the ball joints had failed and that there was no play. Everything was fine until I went to pump new grease in. I would get one or two pumps in then it would start spewing out of a little hole on the boot. Are these holes there for a reason and if they are damaged, is there a way to get a new boot or am I going to have to get new ball joints?
