Like Chris said, there is a cap for the upper balljoint. it looks like you didn't put the snap ring on your upper balljoint the goes in the gap between the knuckle and the bottom portion of the ball joint. you definitely need those on there. you don't want your knuckle coming loose going down the road.
the threads on that bottom balljoint do look pretty tall. what did you torque the upper and lower to?? I usually put a jack under the knuckle and torque the bottom to 60lb., then the top (using the adjuster) to 50lb., then bottom 140lb. and top to 80lb.
