Original 1946-48 Packard Dealer Service Manual, Section II. This Shop Manual dated 12/47 covers the Reconditioning of the Rear Axle of the 21st and 22nd Series Models. This is what the Dealer used to service and repair these Cars. It has information, illustrations and procedures for servicing the Rear Axle of your Car. It is in good condition with minor wear and soiling [see photos]. Very rare and informative tool for the Packard Owner.
