100 Series front diff rebuild

Hi guys



I have 2001 petrol live axle front-end Landcruiser with blown front diff and have decided to remove/replace the diff myself and then have diff rebuilt.



Can you offer advice on :



Workshop Manual avaliability?

Who is best in Melbourne Australia to rebuild the diff?

What are the gotcha's in removal and refitting of the diff?

Any upgrades that I should do while the diff is out?



Hope you can help



Regards



Ken
