My ghetto car loader. Remove the adhesive from the center of the tape using a cotton swab dipped in rubbing alcohol.Place rear beam upside down,(track on the bottom) & gently slide car onto track. Tip beam on side & use razor knife to pry tape from edge of car. Grasp tape with tweezers & pull out from end of car. Presto, traveler reinstalled.
MUMMP later posted a better idea, use shaving cream to hold the bearings in place, it will readily wash out later. Point is, in a bind you don't need a car loader.
