Well ive got it out eventually
I tried using bolts through the holes on the shaft with nuts behind the head of the shaft to act as a puller + would not budge, kept stripping the threads
Couldnt get a bar all the way through the diff
I ended up wrapping a strap round the head of the shaft + towing it out, didnt like it though + rangie moved about a foot sideways while doing it
The last 1/4 inch of the splines had twisted + the diff centre was empty, all the bits in the bottow of the casing, lots of bits
At least i can now get on + finish it
Cheers for looking
