This might be a dumb question but well what is the long aluminium bar that goes from one side to the other in the trunk called? its the one that says maximum 75lbs and 30kg. Ever since i got my ssr, i have been getting this really loud and annoying squeky sound. after i got fed up, i opened up the trunk and thought maybe it might be the bar. so i completely took it off and am left with two loose metal things that are on both sides. I am new to trucks and i really dont know what that is or whats its real purpose. any help would be greatly appreciated since my local GM dealer doesnt even want to touch the car. (we dont get SSRs in this part of the world).
