I have a 04 Dodge Ram 1500 Hemi 2 wheel drive. Recently I've been noticing a loud click coming from underneath/front of the truck. It tends to do it more when I'm about to come to a stop. It may do it a couple times at a stand still but otherwise I can't replicate it. When starting out or at higher RPMs it won't ever do it. I can't narrow it down to any one thing. Bad caliper maybe not fully engaging?? Any help would be greatly appreciated. Thanks

 

I'd start be lifting each wheel and spinning it. Looking for/listening to it and try to isolate it that way.
