The differential itself is the item with the 8 bolts on the inner part of it, and 6 on the outer flange of it. Is this is what you mean by the hub? If so, those 8 bolts all go through the differential assembly and a hub on the rear of that assembly. They have to come out to remove the differential. Leave the outer ring of 6 bolts and the outside flange in place, they hold both halves together as each of the 8 bolts has a gear and spring associated with it, alternating on opposite sides, internally.

If you are trying to remove the axle shaft you will have to remove the differential. In your top picture you can see the gear inside the differential. It has two keys that hold it in place. The axle will not slide out the other side with the keys in place.

do you have take the differential apartto get it off the axle?JJ

id="quote">No, take the nuts off the back of the 8 bolts, and the diff will slide off as a unit.Leave the bolts in it though, or the gears will fall out of place.That unit by the way has been apart before I think. Every one I have ever taken off has the nuts on the outside, not the inside.A hint for the ones with the nuts on the outside.I take an extra bolt, remove one nut and push the old bolt out with the extra, then use the one you pushed out to do the next one. This gets the bolt heads to the outside, so when you remove the diff the bolts can stay in and it doesn't fall apart.Not sure why they put the bolts in from the back at the factory, makes more sense from the front

I'll throw in my usual caution to stuff a small rag inside the bottom of the open differential case below the axle, so the keys don't fall in there. Hard to get them out without disassembling the diff if they do.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
