i did mine myself on a 98 4-door. it took about 1 1/2 hrs. i had never done one before. i had to take the strut bolts off on both sides @ once & also had to remove the factory supports to get it on. then put the factories back on loose & alighn everything up before tightning it all up.
just keep in mind that they don't have to be torqued down too tight. my dubby did his & tightened one of the factory bolts too tight & snapped it off :madfawk:
