Description:
Combination jack, grease pot and axle nut wrench. In use, the wrench would be used to remove and hold the axle nut, the jack used to lift and prop the axle while the wheel was slid off, and the grease daub in the handle used to lubricate the axle hub. The notched bar would form the third side of the triangle to hold the jack in position with the axle elevated. The tool folds for relatively compact storage.
