The "y-shaped yoke" you mention is probably item 7 in this diagram.
According to the manual the sequence is:
remove hub nut
disconnect arb droplink from the damper fork
undo upper wishbone ball joint
remove lower fork connecting shock absorber to lower wishbone
Unbolt the inner end of the driveshaft.
This allows you to swing the suspension upright outward and remove the driveshaft.
Refitting is a reverse but the manual says that the difference between B and A in the attached picture must be 48mm.
Undoing the big bolt joining the damper fork to the lower wishbone was a right pig, lots of aluminium to steel corrosion!
