"Recommended Chemical Products and Sealants".
CAUTION:
Remove any old sealant adheri ng to the mating surfaces.
Also remove any moisture, oil, or foreign material adhering
to the application and mating surfaces.
2. Install the carrier cover to the gear carrier. Tighten the bolts to the specified torque. Refer to DLN-217, "Disassembly and
Assembly".
3. Install the front final drive assembly. Refer to DLN-215,
