Axel seal help for my 62 Dodge Lancer

I agree, the puller is necessary to get drum off.i bought a snap on one, wasnt horrible expensive but made the job a snap. The big nut is supposed to be 40 foot lbs or something. Lots of people think it holds the entire car together and get carried away. Buddy did it after i told him to be careful tightening it. I have to cut it off.
The axle has a flange, not tapered ends, the drum is held in place by the lug nuts.
So I guess I better plan to get inner and outer seals and new bearings. It looks like the only way to get at the outer seal is to press off the bearings. Does this sound right?

to further confuse the issue, the rear axle bearings listed on Rock Auto are cone bearings with separate races, the bearing shown in the repair manual appears to be a roller bearing, one piece that is housed in a recess at the end of the axle housing. I was hoping to have the parts in hand before I pulled it apart but I guess that was wishful thinking
Thanks, Bill
