I need to swap out a worn rear wire wheel hub on my 73 Midget, and was wondering if anyone had done this before? I have heard two different sides on how to do it from folks around here, so I haven't done it yet for fear of screwing something up (I don't want my wheels falling off!) On one hand, I have heard that the axle shaft and the hub must be swapped as a unit, that I need to purchase a new axle to go along with my new hub. Other side says just pull the old hub off and press the new one on, as long as the splines on the axle are ok. Which way should I go?
