I discovered the axles both feel a little loose, and if I twist them back and forth on their play, banging the play one side to the other, it kinda makes the sound. I don't know how play the axles should have, but I'm guessing its 'none'.
So maybe I have bad axles? Car has 115k miles. Looks like original axles. I know there is some driveline snatch I can feel at low speeds if I'm rough with throttle on/off. Is there a definitive bad axle test?
Car has never been lowered. Stock. Ap2. Axle nut retorque done 2 years ago. No clicking now or ever.

Are the trans mounts oil filled like motor mounts are? One has a brown film like you see on blown diff and motor mounts.
