I've removed this bar multiple times while doing work on the car and am curious if that bar is required or not. Does it do anything of significance for my car or can I just remove it. As of right now removing the bar is the only thing that I can think of that would remedy this loud rattle. Any assistance or advice would be greatly appreciated. Thanks in advance. And if there has been any other threads regarding this topic, I apologize, I probably just didn't know how to word the search.
