I even touched them lightly with an impact to be sure.. They didn't move. We went through all the ball joints. the lower ball joint on the right was easily tightened a little more than one turn. The lower ball joint on the driver's side was next to loose. It took three and one half turns. Test drive. No clunks.

After his next track session we had a clunk. The nut on the driver's side upper endlink stud was almost finger loose. Keep in mind, this is the same nut we tried to move with hand wrenches and couldn't budge it. The same nut I burped with an impact wrench. After one track session it was loose.

The flanged deep quenched nut is the issue. For a trackside fix, we used LocTitie, let it sit about 90 minutes and turned the driver loose. He completed hiss session with no clunks afterward.

The real fix is to use special anti-vibration washers on this 12mm stud. They are not cheap. You'll pay $1.25 to $2 for a single washer setup, but $8 to permanently solve a problem is cheap. Check out the video.

Did you lift your car using the floor jack in the front/center like that? I don't think there's a suitable lift point there (with the aluminum shear panel in place).
