Can you check if the driver's side CV axle has any in/out play? Mine does have, especially if trying to move it from the inner CV case. Kind of like and as if the grease is this and the snap ring that holds the shaft in the transmission has play in it. Should have made a video of it.
The passenger front CV is tight with no play, so are both rear shafts. It is only the front Left (driver's) side.
I have had a clunking noise for a few years now that comes when I press on the accelerator pedal from coasting, which usually is an indication of a trans and/or engine mount, but even after changing all 5 mounts the clunking is still there.
This video is for an Explorer, but gives an idea of the play:
