My initial attempt at removing the rear hubs ended in failure.
More research. I called the guys at the Daimler and Jaguar Spare Parts Club. They had the same Churchill tool I’d used earlier and as a member I could borrow it. An alternative suggestion was to take the axle to a engineering firm and have them press the hub off. It sounded so easy, but how? The oil seal retaining bolts looked inaccessible to me.
During a long search through the Jag-Lovers forums, I found a brief reference about someone using a Dremel tool to cut screwdriver slots into the ends of the oil seal retaining bolts, and removing them that way. I wasn’t convinced that this would work, but at least it was a way forward.
Interestingly, the Service manuals I have seen consistently show the bolts reversed from how they are on my axles, and I assume others, or this approach wouldn’t work. As I had already damaged the right side axle, I decided to try this approach on that side.
I have a small air cut-off tool which I used to cut the slots. I considered buying a Dremel tool but decided to save time and money by using what was to hand.
I first got the nut freed up (it and the bolt rotating together). Even this required a sharp crack on the end of the 3/8 drive socket ratchet, which only just fitted, to get things moving. Then, as carefully as possible, I cut a slot in the end of the most accessible bolt. Luckily there was enough of the thread protruding to make this reasonably straightforward. With a bit of practise I got better at this.
With a ring spanner on the nut, locking it, I began the process of screwing the bolt through the nut. Let’s just say it was painful and I resorted to an impact driver to get the bolt through the nut. Eventually success! I don’t know how long this took, 40 minutes at least, but it was shaping up to be a long slow afternoon!
Onto the next one, again being super careful cutting the slot. Unbelievable!. Two minutes later the nut was off. Maybe a bit longer for the third one, but not much. The fourth took a while but it was in behind the brake carrier, and was more fiddly, so maybe 15 minutes. All done!
Next step (now way ahead of expected schedule) was to work my way around the back of the disk with a block of wood and copper hammer. It needed a few solid whacks, but I could tell it was moving and before long the hub and axle shaft were free.
At this point I decided not to push my luck any further and headed for the fridge!
This approach now seemed so straightforward that I had no hesitation in following it on the other side. This was much faster, with only one stubborn bolt taking some time.
I took the hub and axle assemblies to a workshop where they were separated with a press.
The right hub only required about two tons of pressure, I must have been nearly there! The left side (which I hadn’t tried to remove) needed about 20 tons to get it off the shaft. This left me happy with my decision not to try and remove it at home. They also cleaned up the damaged threads for me. So no permanent damage done, as far as I can tell at this stage.
