Abstract: The vehicle differential includes a housing (40) having at least one bearing seat (41) that is aligned along an axis. The housing also includes a counter bore having an internal thread. A bearing assembly (20) located in at least one bearing seat (41) supports a pinion shaft. The bearing assembly (20) comprises a bearing (38) and a lock member (62). The bearing (38) is located in at least one bearing seat (41) and around the pinion shaft. The bearing (38) includes an outer race (45), an inner race (46) and rolling elements (47). The outer race has a raceway (48) that is inclined with respect to the axis. The outer race (45) also has an external thread (49) on the narrow/thin section of the outer race, that is located around the outer race (45) and that is engaged with the internal thread (43) of the housing counter bore to set the bearing (38) along the axis.

Abstract: An axle center for the forward axle in a vehicle having tandem drive axles includes a housing containing input, output and through shafts that rotate in the housing about a common axis on front, rear and through shaft antifriction bearings. The front and rear bearings, which support the input and output shafts, are mounted in opposition. The front bearing has an outer race provided with an external thread that engages an internal thread within the housing. That outer race is fitted with a locking ring provided with an inner flange that is engaged to turn the race and thereby bring the front and rear bearings into the correct adjustment. The locking ring also has an outer flange which is engaged with the housing once the front and rear bearings are correctly adjusted so as to maintain the correct adjustment.

Abstract: A vehicle differential includes a housing having bearing seats and a carrier provided with stub shafts which project into the bearing seats. The carrier is supported in the housing on two single row tapered roller bearings which allow the carrier to rotate, but confine it radially and axially. The housing also contains a beveled pinion which meshes with a beveled ring gear that is attached to the carrier. The two bearings are mounted in opposition and each includes a cup that is located in the bearing seat for that bearing, a cone that fits around the stub axle that projects into that bearing seat, and tapered rollers located between the cup and cone. Each bearing seat contains an internal thread and the bearing cup which fits into the seat has an external thread that engages the internal thread. Each cup also carries a locking ring which is engaged by an adjustment tool to turn the cup, but is later deformed into the housing to secure the cup against rotation.
