3. To disassemble the axle housing assembly,
carefully position the axle housing assembly on a
clean flat surface, then separate axle housing from
the planetary assemblies.
4. Position the axle housing assembly with the output
end of the axle shaft in the up position. Using a No.
5 or 7 internal retaining ring pliers, remove the
retaining ring from the axle shaft.
5. Reposition the axle housing with the splined end of
the axle in the up position. Using a No. 4 or 5
