So....this is my first time here. I've had my 2005 fx35 for almost a year now. Love it, but it started making a loud Clicking noise up front (only under load.) Like if you stopped on a hill, then got in the gas a little it was a sound like an axle slipping or some thing. I guess its more of a clunking than a clicking. Well now that sound is gone. But the awd won't engage. I stopped on a gravel hill today and only the rear tire will spin. Not good. Has anyone had this happen before? Thanks for any help!
