Ball joints? (greasing)

[10 CYL]

My GTS is on axle stands as I am refurbishing all the suspension, however I now have to grease the ball joints.
My question is how much grease do I pump in, is there a way to tell that I am not over greasing.

thx

From what I’ve read on the subject you do it until you just feel the boot start to expand. Too much and it will ooze out making a mess. Not done it myself yet as it’s on my list to do in the next couple of weeks at the same time as the brake fluid.
