As I had a Ball joint loosen in the front Left control arm, I removed both left and right and checked/adjusted the Lash. Both were a little loose after 20+ Track days. First you have to remove the ball joint from the spindle, and then remove the Ball joint from the Control arm -- it is screwed in, but you need a 1 59/64" Ball joint socket -- here's a link: http://www.amazon.com/gp/product/B003IOEQ1O/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 Once the Ball joint is out, you need to remove the c-clip: An the Hex Plate retainer: At this point before dis-assembly I checked the Lash (see below) it was over a quarter turn loose, both sides. Then unscrew the plastic hex adjuster cap to expose the ball: Remove and clean. My wear patterns were fairly uniform: Then re-assemble, and tighten the plastic adjuster until it contacts with the bottom of the ball, back off 1/8 of a turn and replace the retaining plate and the c-clip. Add a couple of squirts of grease and re-assemble in the control arm. Torque spec for the control arm is 100 ft-lbs.
