First of all, it arrived in the same condition it left the manufacturer. Really Moog! I've seen people do just that when they have no idea how to fit a trunk clip over a dust cover. They ignore it and let a flat ring of wire rip open the trunk. You need better control. I solved your confusion in a bad way by sending the part back. I needed a car so I used Toyota silicone to fix your bad job. I hope the next time someone buys a Moog ball joint doesn't have to deal with it. Even after this shoe has been repaired, it is still in use. Possibly because the part does not come from the Detroit axis. If it were, I'd be turning in a ditch.
