The plastic piece that holds the rear swaybar appears to have pulled off. I'm trying to put it back on and it appears that it just has 2 screws that hold it in. I tighten the screws all the way, it seems solid and then I compress the suspension and the sway bar pulls right out. I'm trying to figure out if its just those two screws that hold in the piece that holds the sway bar on or maybe i"m missing something.
