ABSTRACT:
A differential of the helical gear type is disclosed for vehicles including an improved sectional spacer device having a generally C-shaped outer spacer section for maintaining the side gears in axially spaced relation, and a removable inner core spacer section for maintaining the axle shafts in axially spaced relation and for supporting the leg portions of the outer section against displacement toward each other. Spring devices are non-rotatably mounted in the housing for biasing the side gears axially inwardly toward the outer spacer section, thereby to reduce the clearances between the side gears and the outer spacer section, respectively, whereby differential backlash is reduced.
