- Raise the temperature of bearing cone (20). Use the proper equipment to handle bearing cone (20).
- Install bearing cone (20) on the axle shaft. Make sure that bearing cone (20) is seated against the shoulder of the axle shaft.
Note: Allow bearing cone (20) and the axle shaft to reach a uniform temperature.
- Use a suitable driver to reset bearing cone (20). This will ensure that bearing cone (20) is seated properly.
- Apply a thin coat of clean SAE 30 oil on bearing cone (20).
- Use Tooling (H) to install Duo-Cone seal (21) in the axle shaft. Refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install".

Illustration 2 g01274269 - Lower the temperature of bearing cup (19). Use the proper equipment to handle bearing cup (19).
- Install bearing cup (19) in the end of axle housing (1). Make sure that bearing cup (19) is seated with the mating surface.
Note: Allow bearing cup (19) and axle housing (1) to reach a uniform temperature.
- Use a suitable driver or a press to reset bearing cup (19). This will ensure that bearing cup (19) is seated properly.
- Use Tooling (H) to install Duo-Cone seal (18) in the end of axle housing (1). Refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install".

Illustration 3 g01274267 - Lower the temperature of bearing cup (15). Use the proper equipment to handle bearing cup (15).
- Install bearing cup (15) in the opposite end of axle housing (1). Make sure that bearing cup (15) is seated on the mating surface.
Note: Allow bearing cup (15) and axle housing (1) to reach a uniform temperature.
- Use a suitable driver or a press to reset bearing cup (15). This will ensure that bearing cup (15) is seated properly.
- Lower the temperature of ring gear (17). Use the proper equipment to handle ring gear (17).
- Align the dowel holes in ring gear (17) and axle housing (1).
- Install ring gear (17) and dowels (16).
- Peen axle housing (1) near dowels (16) to retain dowels (16).

Illustration 4 g01274293 - Attach Tooling (A) and a suitable lifting device to axle housing (1). The weight of axle housing (1) is approximately
205 kg (450 lb) . - Install axle housing (1) onto the axle shaft.
- Raise the temperature of bearing cone (14). Use the proper equipment to handle bearing cone (14).
- Install bearing cone (14) on the axle shaft so that there is slight end play. When bearing cone (14) is cool, apply clean SAE 30 oil to bearing cone (14).

Illustration 6 g01047406 - Install Tooling (G) on the axle housing.
Note: Tooling (G) will be used to measure the seal drag torque that is required to rotate the axle housing.
- Use Tooling (G) to rotate the axle housing.
- Record the torque that is required to rotate the axle housing as Torque (X).
- The torque that is required for bearing nut (13) should be equal to Torque (X) plus the axle bearing preload rolling torque.
Note: The preload rolling torque for new bearings is
1.0 to 1.8 N·m (8.85 to 15.93 lb in) . The preload rolling torque for used bearings is0.5 ± 0.9 N·m (4.43 ± 7.96 lb in) . - Use Tooling (G) and Tooling (E) to obtain the correct rolling torque for the axle housing.
Note: Make sure that the axle shaft has zero end play. If the axle bearing preload rolling torque exceeds the specification, back off bearing nut (13) by 1/8 turn and reseat bearing cone (14) against bearing nut (13). Repeat Steps 22 through 26.
- Use the following procedure to assemble the planetary carrier:
- Apply a thin coat of clean SAE 30 oil on all parts of planetary carrier (6).
- Install bearing (12) into planetary gear (11).
- Install two thrust washers (10) and planetary gear (11) into planetary carrier (6).
Note: Retaining ring (4) (not shown) must be installed in the planetary carrier assembly before the final planetary gear is installed in planetary carrier (6).
- Install planetary shaft (9) into planetary carrier (6). Make sure that the spring pin hole in planetary shaft (9) is aligned with the spring pin hole in planetary carrier (6).
- Install spring pin (8) into planetary carrier (6) and into planetary shaft (9).
- Install spring pin (7) through planetary carrier (6) and in spring pin (8).
- Repeat Steps 27.a through 27.f for the installation of the other two planetary gears.
