Even though it was easy to put together,the instructions are very vague as to how to actually assembly them. Once on the car they are tight and solid. Total time from start to finish was about 30 minutes. I don't notice any sound. They come with white arrow indicators for quick removal and reattaching. I only use them to haul my kayak so I remove them each time. 5 minutes to reattach. Overall a good buy.
