Rookie question, I'm sure, but I'm trying to put the front suspension back together on my wife's 55. I got a set of Polyplus upper bump stops from CCP and can't seem to get the stinkers to press into the hole. I've tried a bit of grease, a clamp, twisting, a hammer, and even using a string to help pull it through. No dice. I tried to search for help, but it doesn't seem like anyone else has struggled with the upper bump stops.
