86' 3/4 ton 4X4
I've got what sounds like a clicking sound coming somewhere from the rear end when moving slowly forward. It progresses with speed to a rhythmic rubbing type sound. Before I go digging into the wrong system for no reason, I was wondering if this is a tell tale sound of something specific, like the rear U-joint, rear (drum) brakes or wheel bearings, or differential. Thanks for any input.
