The wider end of the seal goes against the inside of the control arm. The narrower end of the seal goes over the end of the shaft and sits snug against the shoulder on the shaft. If you think about it it makes sense, because when the bushing threads into the control arm the rear of it needs to make it inside part of that seal. It has to be this way so you can fill the pocket with grease. Otherwise how the heck would you get grease into that little space?
