So I've been noticing for months that the cover over the ultrasonic sensor in the driver side front wheel well has been out of place. I could stick my finger between the opening of it, and the painted edge of the wheel well. Today I tried to pop it back in place, and put the hole in it over the plastic stud sticking out of the sensor. Then I went around and took a look at the one on the other side, and saw that the edges of this little rubber cover were tucked behind the wheel well liner. On the driver's side, the edges are on the outside of the liner. How is this supposed to go?
