I have a 2006 Tiburon 2.7 and plan on replacing all 4 struts next week. I have bought pre-assembled/‘loaded’ struts. Will I need to still compress the spring to remove or install pre-assembled struts or is it just plug & play (unbolt and replace)? I have never messed with suspension before and keep getting mixed messages from several different sources. Figured I would ask before I end up in an emergency room from an impaled strut.
