Hi, Armada guys and gals. I'm a Titan owner and got my truck almost rattle free. May be some one can help me out. I got a rattle (more like a click or a ticking sound) in the dash some where between the nav. system and passenger door. Sometimes it sounds like its under the nav. system. This is not the ground fix. It occurs on wash board roads or on roads with frost heaves or sharp bumps. In time with the bumps not RPM's. It's mostly at highway speeds and is not constant. Yesterday it reared its ugly head driving around 25 MPH on a frost heave street. I tried everything I can think of, short of pulling out the whole dash. If anyone has any ideas or knows what this is please post a reply. For the record I didn't do the ground fix. I have not had the exact same symptoms as the people who did do the fix. Thanks.
