Note: The following procedure controls bearing preload. The procedure provides the same results for new bearings and for used bearings.
Assemble differential group (15) .
Heat bevel gear (16) to 135°C (275°F) for a maximum of four hours. Install the bevel gear on the differential group.
Install four large pins (25) partially into bevel gear (16). Install four small pins (26) into large pins (25) and press all pins (25) and (26) so that the pins are flush with the surface of bevel gear (16). Torque 12 bolts (17) to 300 40 N m (220 30 lb ft). Make sure that the bevel gear is seated on the differential group shoulder.Note: Bolts (17) for the bevel gear must not be substituted with other bolts. Bolts (17) must only be replaced with identical parts.
Press bearing cone (4) and bearing cone (22) on differential case (21). Make sure that the bearing cones are fully seated.Note: If you heat the bearing cones, allow the parts to reach a uniform temperature. Then use a driver or a press to reset the bearing cones. The limit for heating the bearing cones is a maximum of 135°C (275°F) for a maximum of four hours. Lubricate the bearing cones with SAE 30W gear oil after the bearing cones have cooled in order to prevent rust.
Remove intermediate housing (14) from center housing (27) .
Position center housing (27) in an appropriate supporting fixture so that the open side faces upward. Use a lifting device to lower differential group (15) and bevel gear (16) into position on three dowels in center housing (27) .
Install intermediate housing (14) on center housing (27). Tighten the bolts.
Install bearing cups (5) and (23), bearing sleeves (1) and (18), and two pins (24). Lubricate the threads of adjusting nuts (3) and (20) and install the nuts in intermediate housing (14) and in center housing (27) .Note: If you freeze the bearing cups, allow the parts to reach a uniform temperature. Then use a driver or a press to reset the bearing cups. The limit for freezing the bearing cups is -29°C (-20°F). Remove any frost and wipe the bearing cups dry. Lubricate the bearing cups with SAE 30W gear oil in order to prevent rust.
Lubricate the O-ring seal and install the O-ring seal on pinion housing (9). Install pinion housing (9) on center housing (27). To install the front differential, torque the eight bolts to 300 40 N m (220 30 lb ft). To install
