I got 70 rear & can't seem to get the axle shafts to separate from the hub. Hub has studs not bolts holding shafts to it (unlike my 14bolt). I think it has some cone washers on the studs from what I can see. What's the best way to get the shafts out? I may take a big ass hammer & whack the center to see if it jars it loose. Any suggestions? Thanks.
