Thoroughly clean the parts of the service brakes.Note: When brake service is required, replace both friction discs. Replace all piston seals and all retraction springs. Inspect all surfaces for wear. Replace components, as required. Refer to Testing and Adjusting, RENR4317 for further information.
Illustration 1 g00451337
Apply 8C-8422 RTV Silicone Sealant to dowel (7) . Install dowel (7) . Seat dowel (7) in the bottom of the bore.
Apply clean SAE 30 power train oil to O-ring seal (8) . Install O-ring seal (8) and install pin (9) .

Illustration 3 g02111173
If necessary, install dowels (6) and (12) . Seat the dowels in the bottom of the bores.
Install seal (16) and seal (17) .
Apply petroleum jelly to seal (16) and seal (17) .
Apply clean hydraulic oil to piston (15) .Note: Install piston (15) evenly. Twisting or binding of the piston may cause seal damage.
Install piston (15) in the differential housing assembly.Note: Using a friction disc with less than 7.65 mm (.301 inch) of friction material will result in accelerated wear. Do not use the color of the friction disc as an indication of wear. The overall thickness and disc groove depth are better indications of wear.
Inspect friction disc (13) for wear. Replace the friction disc if the thickness of the friction material is less than 7.65 mm (.301 inch). Immerse the friction discs in clean SAE 30 oil. Install friction disc (13) , reaction plate (14) , and friction disc (13) .
Install cup (11) and spring (10) .
Install two springs (5) .
Install reaction plate (4) .
Illustration 4 g00451323
Install sun gear (3) .
Illustration 5 g00451163
Apply 6V-6640 RTV Silicone Sealant on the mating surfaces of the axle housing and differential housing.
Attach Tooling (A) and a suitable hoist to the rim of the axle shaft. Use the hoist in order to carefully install the axle housing assembly. The weight of axle housing assembly (2) is 365 kg (800 lb).
Illustration 6 g00450664
Install bolts (1) that secure axle housing assembly (2) to the differential housing. The torque for bolts (1) is 300 40 N m (220 30 lb ft).Note: If you install new service brakes, record the dimension in order to calculate wear. Refer to Operation and Maintenance Manual, SEBU7459 for further information.
Record the new dimension in order to calculate wear.
Repeat Steps 1 through 17 for the remaining service brake.End By:
Install the fixed axle. Refer to Disassembly and Assembly, "Fixed Axle (Front) - Install".
Install the oscillating axle. Refer to Disassembly and Assembly, "Oscillating Axle (Rear) - Install".
