Abstract: A cargo trailer wheel hub puller has a housing provided with a hub which loosely supports a bushing internally provided with threads. A pin passes through a hole in the hub to maintain the bushing in the hub. The bushing is provided with a collar which abuts an internal wall in the housing. A threaded rod passes in thread engagement through the bushing. The end of the rod inside the housing is provided with a contact pad which is adapted to apply a force against a vehicle axle while a torque force is applied to the other end of the rod so that the housing, which is attached to the structure of the trailer wheel hub is forced outwardly over the vehicle axle. The bushing is made from a milder steel than the rod so that, upon wearing out, it can be readily replaced by removing the pin and replacing the bushing.
