In total you will have to do this 4 times, two for the front and two for the back. The only thing to note it that in the instructions it points out the different sizes of ball stud cover and it is obvious which one goes where, but what it does not tell you, and it cannot be clearly determined in the pictures, is which way up the completed assembly goes. After trying it both ways and then looking for pictures on the Internet I can tell you that the longer of the ball stud housings connects to the upper wishbone.
The larger of the ball stud housings goes at the top.
