4.9.1 Re-Shimming the Backlash
NOTE : This step is only necessary when adjusting for
incorrect backlash.
c Reapply the spreader to the differential housing.
c Remove the bearing caps.
c Remove the differential.
c To increase the amount of backlash, reduce the shim thickness ‘D’
(Fig.5.) and increase the shim thickness ‘E’ (Fig.8.) by the same
amount. Reverse this step to decrease the backlash.
c Remount the differential as before.
c Release spreader tension.
c Check backlash again as before.
4.10 Profiling the Seal Housing Tube
c Without using sharp, jagged tools such as pliers (usually your
hands are the best tool for this job), bend the seal housing tube so
that it closely follows the profile of the differential housing and
protrudes through the bulkhead port in the differential housing.
(Fig. 17.)
Figure 17.
c Check that the contour of the tube will not interfere with the ring
gear, differential, or the cover plate.
