he's probably referring to the ball instead of the actual set screw. The set screw will not come loose. The ball on mine came loose too. I just used a longer set screw so you can go all the way into the knuckle to grab as much plastic as it can. I do this for the bottom screw too. Then lock tightened the ball to the set screw. Basically made it one piece like the other cars.
