Nut splitters work well; I use a Sykes Pickavant but sometimes access can be tricky.

If you do what Groucho suggested, drill through the nut with a suitably sized drill bit parallel to the thread but far enough away not to damage it. If you do this diametrically opposite each other and then whack it with a sharp cold chisel and a heavy hammer, it will split easily and save you the cost of a nut splitter :D

Are you sure a good quality socket, metric, or AF will not grip on the bolt on the drive flange? It doesn't look too badly damaged to me but certainly needs replacing,

Worth noting that the bolts on the drive flange are neither metric nor AF - the heads are Whitworth and they are BSF thread. (Just about the last bit of BSF on late Series 3, unless I am mistaken - same bolts from the very first Landrovers!)

Trying to use the wrong size socket (or a shifter) may explain the condition of the heads. Also worth noting that these bolts are often overtightened and stretch. The resulting necking of the shank makes them a looser fit in the hole and may lead to movement on the flange, with resultant oil leaks, although this is often also a pointer to loose wheel bearings.

On the flange bolts you have a choice
remove the grease nipple and use a small pair of stillsons
Hammer on a socket that will fit
or weld a nut on the bolt
If they are original bolts they should not bottom in the hole so they should
not be that tight .........

Update -

Checked out the Supercheap Auto link (thanks Sleepy!), went to Mittagong in the early hours of the morning, they don't stock nut splitters...

Neither do Bunnings, Home Timber & Hardware, an auto store in Mittagong & an auto store in Moss Vale - none of the people had any idea what I was talking about...

I'll try another Supercheap when I'm up in Sydney...

I'd like to save the bolt, which means no cold chisel - I was asking my grandfather for advice, and asked him (in all seriousness) how cold the chisel had to be :oops2:

Don't bother looking at those cheap places for a nut splitter
Thats what they will be Cheap.......
You probably won't get a nut spitter under the diff centre nut anyway.

Why do you want to save the non functional bolt on the flange
with the rounded head ? Its Quite obvious that the previous owner didn't have the right size socket. Unless you are realy attached to that bolt
throw it away.........

I hadn't considered the space under the nut - you're completely right (it's very, very close).

And I didn't realise that the non-functional bolt was non-functional :angel: - not to mention easily replaceable...

I'll go out and have a good whack - I'm worried about the diff though; if I essentially cut off the nut & bolt, can I replace the bolt (i.e. how is the bolt attached to the back of the diff? Anyone have a pic?)

As always - thank you all!

Cheers,
Dave

The bolts on the diff housing are stud bolts which press into the inside of the housing.. Here is a pic..

If you split the nut carefully they are soft. you should still have the stud left.
They are splined and tap in from the inside......
Don't snap the bolt in the flange or you will have to drill it out.

Thanks - that's very helpful (and timely!)

How are they pressed in? Would I be able to do it?

Tap em in with the hammer..........
