U-Joints?

Of recent, I notice a light, metallic click - click - click in the drive line that speeds and slows in frequency with speed of car. Really only noticable at low speed, like when parking or pulling in and out of the garage. My first thought was u-joints, but upon inspection, they seem OK, which is to say no freeplay in the joint itself. They are the one wing, one round cap type. Am I missing something? Any thoughts?
