I got a rental 02/07 titan CC this weekend and was checking it out... The tailgate is light but I dont think its that when I let it go it sounds like there is a piston letting it down slowly... I remember about the torsion bar or whatever they were called some people would add to help but I looked and nothing... I remember the 05 guys talkin bout a piston welded to the bed... but this one doesnt have anything... it sounds like its inside the tailight or something... is there a difference in (well of course from 04 cuz it didnt have anything) the 05s - 07s? How does the tailagte of the 07 work? Can it be done to an 04? Ive never really seen the mechanism for the 05 or any of them... I just remember reading bout them and MAYBE seeing a pic of how it attached to the bed in an 05... I dunno...
