I think this is the second time it happened- driving straight at about 30mph and POP! I'm like WTH? I look around expecting to see a broken window. Nothing, didn't feel anything either. Thought maybe a bird dropped a walnut and maybe hit my sunroof? But thinking back I heard a sound similar to this a few weeks ago and thought maybe I ran over a branch or something... man WK's have the most bizarre sounds. I've had a bad sway bar link on my ZJ before but it wasn't like that. Anybody experience a loud pop like your back window just blew out?
