A differential has an input drive member 12 in the form of a sleeve which can be connected via a clutch pack 54 to a differential gear carrier 18, which carries two bevel gears 30,32 which each drive an output shaft 42,46 respectively. A further clutch pack 60 is provided. A ball ramp mechanism 76,80,81 actuates the engagement of each clutch pack 54,60 in turn to allow both output shafts to be driven and have differential rotation (via engagement of the second clutch pack 60) and through further actuation, to lock the differential (via engagement of clutch 54).
