There were no signs of the problem, I checked the car over pretty good. Just put the shock back on and eveything looked ok. I agree all the ball joints should be replaced.

You are correct, it's not at the transition to the threads. I was at work this morning when I resonded and was in a hurry. I just went back and looked at your pictures again, and I will however stand by my comment that the final failure occured at the dark gray area. The light gray area had fractured at some time in the past.

Unfortunately my work days just went from 12 hours to 14 for at least the next few weeks. Hopefully I will have this Sunday off. If so, if no other engineer has chimed in by that time I will take a couple of your pictures and point out some things to you.

If time allows I will have one of our stress engineers at work take a quick look at a couple of your pictures and see if he agrees with my analysis.
