According to the dictionary these words do not help to define what has been done; the descriptions are not distinct (and so cannot be used incorrectly); a description of the actual activities done on an item should be more helpful.
Rebuilt: repair, especially to dismantle and reassemble with new parts
Recondition: restore to a good or satisfactory condition; repair; make over
Refurbish: to furbish (to restore to freshness of appearance or good condition) again; renovate; brighten
Restore: to bring back to a former, original, or normal condition
