are you talkin about the rear? because in the fronts the strut bearings or like top hat thing comes off easyI had already removed the struts from the car. And the top hat is held on with a nut but it has like a rubber ring on the inside. But the nut is recessed (sp?) so you can't use a regular wrench. And you can't just use an impact or anything because the rod it's attached to will spin. So i had to use a T-handle allen wrench and an open ended socket. To hold the strut while i turned the nut. But like i said i was working alone in the parking lot and didn't have a whole lot of tools at my disposal. I'm sure others have much easier ways of doing it.
