Expect some resistance when prying up on the vibration motor. There was some aggressive double sided tape under it and it was stuck pretty firmly.
Some instruction guides also suggest optional use of a suction cup with which to tug on the glass while separating the plastic backing. I found this helpful. Also, if you have a spudger of more rigid plastic, use that one here. My blue spudgers got chewed up pretty badly during this process.
I too bought a used LeapPad 1 unit and harvested the screen. If you do this, be aware that the steel frame that holds the screen differs between the first and second generation LeapPad. (i.e. LeapPad vs. LeapPad 2) The screen is held in the steel frame using very aggressive double sided tape. A heat gun or hair dryer will aid in loosening the adhesive on the tape. Be very careful when prying the frame away - it's all too easy to damage the ribbon cable (this is my second attempt). I used a butter knife to gently pry underneath - it's quite challenging. Also, the LeapPad 1 screen had a slightly wider ribbon cable. I had to use a Dremel cut off wheel to cut away some of the frame. Much to my relief, when I connected the new screen all seems to be well and it does work.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
