I have had one for approx. 5 years. I will warn you to be very sure that the plastic cap on the top of the center vertical beam is securely covering the hole. If not, water will accumulate and possible freeze in winter and crack the tube. Unfortunately I know this from personal experience. Luckily Warn sells a replacement swing out assembly... for $400.
Mine doesn't rattle, but the swing out tended to sag over time. Also the grease fitting for the pivot wouldn't allow grease to enter. I always had to take the fitting off to re-grease. On my 2000 TJ I had to remove the stock license plate holder. It interferes with the latch. I believe the kit comes with a relocation bracket. (at least mine did back then.)
