It's because of the low type 5x9 ball connector (only used in this position) which for some reason is slightly larger than the normal size.
If you want it as free as the rest of the car, use the 1mm higher version included in the 54075 set. But of course you need to be aware that it raises the ball by 1mm. The other way is to try to free up the ball cup...pliers, heat etc., there are different ways to do this, but I personally prefer to change the ball connector.
