Looking to get some input on an sound that I've been hearing for about a year. I have a 2013 2 Door JK and I've been hearing what I can only really describe as a hissing sound that seems to be coming from the back left tire. I only hear it when I'm driving and turn left, it's not terribly loud and can only hear it with the window down. Breaks, calipers, shocks and bearings are all new as well as the tires. I'm pretty handy and can't figure it out, I even broke down and took it to a dealership and they couldn't figure it out. Someone told me that it could be the axle being slightly bent but I don't wanna pull that off without getting more opinions. All and all it seems to just be annoying me more then it is an actual mechanical issue but I don't wanna be wrong. If anyone has any input or suggestions I'd greatly appreciate it.
