A bad assumption on my part led to the incorrectly installed UCA. I definitely took note of the ball joint orientation when I installed the passenger side arm. My mistake happened when I applied the same steps
on the drivers side from the previous day as "I've done this before". Instead I should have applied the same "steps" that led to success on the passenger side.
What I learned from the mistake is to be a more methodical builder and examine each part for correctness AND use the proper thread locker where noted. Had a heck of a time unscrewing the ball joint from the UCA to the point I would not re-use it for cosmetic reasons. That particular brand/part# joint is readily available. $17.00 mistake and a bruised ego is all the damage done.
I'm learning and more importantly, having fun!
