Just had same issue of disagreement on which oil to use. Most non Volvo garages still have old spec for the 2003-2008 AWD models which specs different oils at both ends of the rear drive shaft. Volvo now supply same oil for both ends. Part no 31259380. This is an API GL5 75W-90 oil and same as the original spec for the front transfer box/bevel gear. Don't get put off by the label on the bottle which says for use in bevel gears on all AWD models post 2013 and does not give any indication of the oil grade or viscosity. Very helpful Volvo !
