G'day John.
It's been a while since I did one but it would be easier with the inner cover off but I think can be done in place with an internal puller. (pic att)
To remove the inner cover the pinion nut, pinion, bush, spring and washer comes off. The cover comes off with the bearing. It may be tight on the shaft so may need a few taps on the shaft with a hide mallet and pulling on the cover at the same time.
Cheers
