I've got a seasoned MultiCAM router that they no longer have much on parts for. The stepper motors on the X axis are the Warner KML092F-102. (1.4V, 7Amp)

The second motor has suddenly developed some slack to it. On all the other axis, you cannot push the motors by hand at all with it powered on. However this one now allows for about a 1/2" of back and forth by hand. It is resulting in some pretty funky looking circles and curves.

I would like to replace the pair if this one is bad. I am open to a substitution motor, and could test other circuits and conditions if you think the problem could be something else.
