My tailgate assist torsion bars or whatever they are, are not working right. Does anybody have a pic of what they are supposed to look like with the tailgate open? When I open my Tailgate, it goes about 2/3rds of the way down, then meets with resistance, then a loud BANG as they get past where they are catching. Closing yields similar results. I notice at the ends of the bars, where they loop back toward the center of the truck, there are holes for them to go in to, but mine don't. I can try to post pics if that will help. Please let me know.
