If you remove the cotter pin at the top, you can take a big straight screwdriver and take some of the slope out, then put the pin back in.They are adjustable,and if it's already worn out give us a call we have the replacements in stock
DO what Tommy said and adjust all your tie rod ends to take up the slop. I did that on my 304 and it made a huge difference. So far, I haven't needed to replace then, as I got the adjustment done before they had hammered themselves to oblivion.
I apologize for taking so long to close the loop on this issue, but I did adjust the slop out of the ball joint as instructed by Tommy and it is now as good as new. Thanks Tommy for your help.
