shaft will be here tomorrow morning and assuming it no longer feels like driving a massage chair I’ll look at the pump.
If you mean the shaft to the rear.... it probably needs a new IRD.
Wrong vehicle - Fl1 have the dodgy viscous that seizes up, FL2 use a Haldex clutch on the rear diff, so I don't think they suffer the same set of issues as the FL1.
aha! but this one has its own issues 🙂 the shaft will not come out of the hub, eventually gave in and took the whole lot off and put it in the press - it just bent the hub knuckle casting! so a new casting required, never seen one so stuck. No sign of heat damage but it will not shift.
seems to be a bit of conflicting information out on the 'tinterweb , workshop manual download suggests the drive bolt on the front shaft should be 45Nm + 80 degrees, is there any update or other information contradicting this info?
