I am restoring an early 1949 CJ3A. it appears someone had replaced the original Dana 44 rear axle with a Dana 41 or the early version came with it. Axles and hubs show to be the same. This Dana 41 has the semi floating axle. The outter wheel bearings are shimmed correctly to spec. When i torque the new hubs and drums on the old axle the hub binds up tight. Had anyone had experience with the problem? I would appreciate any input.
