I have a crusty old stock 12 bolt from an el Camino in my car. When I don't drive it much, it gets clicky. Not loud, but you feel it too. An ancient GM tech (RIP) told me drive it in tight figure eights alternately in reverse and forward, slowly. Explaining that, he said it takes lubricant to areas that don't otherwise get it. Beyond that, he said change lube several times (it had sat for twenty years). Those things have always restored quiet operation for me. I know nada about gears. But sort of like how a guy periodically ought to do a few quick stops in reverse to adjust drum brakes, the figure eights work like exercise.
