If anyone is interested, I talked to a Hyundai mechanic and he printed out the instructions from their system on how to remove and reinstall this armrest and it is so simple to do. Lower down drivers side back seat and remove the plastic bolt cover down where the armrest swivels. Remove the bolt and raise up armrest and it will lift up and off the pin holding it on the passengers seat side. Replacement is the opposite. Took less that 5 minutes to take off and fix the cover and reinstall it.
