Both the rear axle outer grease seals were leaking on my 1972 4/4 and needed replacing. As usual for this sort of job I booked it in at my mate Bill's unit because he
(a) Has a very full set of tools
(b) Has a four post car lift. Whereas I can still bend down to work on the car, getting up is a different matter nowadays.
(c) Takes cash.
The first side was a doddle. The hub came off easily, the old seal tapped out of its carrier, and the whole thing was done in half an hour. The other side was a different matter: the hub would't come off for love nor money. We didn't have a suitable attachment for the slide hammer and a hydraulic hub-puller wouldn't shift it. Heating it up didn't improve matters and neither did cooling it down again. In the end discretion became the better part of valour. The next attempt will involve adapting an old wheel spinner to fit the slide hammer and trying to get it off that way.
If all else fails we were wondering about removing the hub and the half-shaft together. Does anyone know if the half-shaft is clipped or otherwise secured at the diff end or does it just pull out?
I've got a decent set of photos of the job which I'll post.
