All 4 of my doors have been rattling since day one, I've tried all the solutions that are on this forum and they work for a little bit but don't completely get rid of the problem. So about 3 weeks ago I came up with the simplest solution.....I took about 2 inches of electrical tape and wrapped it around the door catches, no more rattling! i also wrapped the mounting studs for my bed extender and all i hear now is engine noise.
