4. Remove bolt s and take off differential bearing caps. Caps
and each side of housing are marked with either a figure
or a letter which must match when reassembling, Figure
18.
5. Place rear axle housing spreader (J-5231) in place on
housing with dial indicator mounted as shown and
spread housing .020" by turning the spreader screw. Do
Not spread housing more than this amount or leave
spreader expanded for a long period as this may cause
permanent damage. (Clamps should be used to hold the
spreader to the housing). Spreading the housing to re-
move or Install the differential assembly is necessary due
to the preload or side press of .005" to .009" between
bearing cups and housing.
