shafts the differential assembly 26 includes the gearset 42 that is operable for transferring drive torque from the differential casing 40 to the output shafts 44 and 45 fig1 in a manner that facilitates speed differentiation therebetween gearset 42 may be a helical type and may be disposed within the internal chamber 48 the gearset 42 includes a pair of side gears 68 a and 68 b the side gears have internal splines 70 a and 70 b meshed with external splines not specifically shown on the corresponding output shafts 44 and 45 fig1 in addition the side gears 68 a and 68 b include axial hubs 78 a and 78 b respectively which are retained in corresponding annular sockets 82 a and 82 b formed in the main body 46 and the end cap 50 of the differential casing 40 the side gears 68 a and 68 b also include annular chambers 84 a and 84 b a spacer 86 may be located between the side gears 68 a and 68 b for limiting the amount of axial endplay of the side gears 68 a and 68 b within the differential case 40 a cross pin 90 extends through a passage 92 in the spacer 86 and controls endplay of the axle shafts 44 and 45 fig1 the outer cylindrical surface of cross pin 90 is sized to closely fit passage 92 as such the longitudinal location of cross pin 90 is defined.
