hey AN. good on you for tackling it yourself. i don't have the necessary tools for the job unfortunately.
sorry, i can't really help out much cos i've never done the work. however, the workshop manual refers to disassembling part of the suspension; i presume this allows more ready-access, and allows the 'intermediate driveshaft' to be removed. does that make sense, and have you done that?
you don't mention the bearings, but i presume you have new bearings to fit to the diff. i only ask cos my local service guys told me you cannot remove the originals and reuse them because of likelihood of damaging them during removal. having mine fitted on 29-30 Oct. can't wait.
