Install the axle shaft assembly on the opposite side and push it
in until it fits against the differential thrust block. Then,
measure the clearance (t) between the bearing holder and the
axle case flange and determine the thickness of the shim to be
installed by the following formula :
Measured clearance (t) + 0.3 mm (0.012 in) = thickness of
shim to be installed.
