First post, hoping you guys could help me diagnose this problem. I am driving a JKU 13 Automatic Rubicon . I do plan on taking my JK in for service for this issue but I am curious if anyone else out there had the same problem and what they did to correct it. This noise manifests itself only after the truck is warm and when driving between 40-60 mph. I recorded this with my phone right next to my gear selector. Any and all leads are appreciated. https://soundcloud.com/agm2010/rattle-2

 

Did you find a resolution to the problem? I have a similar issue seems to only happen when accelerating and if I push on the transfer case shift handle the rattle stops. The dealer has been no help. Any thoughts from anyone out there?
