I did mine on my own by taking it apart on the car bit by bit, and then reinstalling it bit by bit.
I fitted poly bushes , it will be coming off again this year to fit standard bushes.
However, I will drop the lot completely this time.
the parts separately are heavy (especially the diff) and not easy to get to the bolts to remove, and afterwards to tighten. (yes especially the diff!) try holding it in the right position to put the bolts in !!!
It looks far easier to drop the lot and then strip it, so I will go that route, learnt from experience.
