Apply high concentration isopropyl alcohol (90% or greater) to the vibration motors through the openings in the bottom of the midframe.

Allow the isopropyl alcohol to soak for one minute to dissolve the adhesive securing the vibration motors to the midframe.

Apply a similarly sized pre-cut adhesive to the new vibration motors if one is not preinstalled. Test-fit the vibration motors before installing them with adhesive to ensure they are in their correct locations.
