If you're struggling with how to remove the rear wheel hubs from a keyed, tapered rear axle shaft, check out my HD video how-to on the use of an OTC hub puller: http://www.4wdmechanix.com/HD-Video-Tool-How-to-Using-the-OTC-7394-Hub-Puller.html.
There's only one way to preserve these parts and get the rear hub loose...Also works on the AMC Model 20 axles and even later model 4x4s with unit bearing front ends and frozen axle shafts...
