2.6 Spreading the Differential Housing
IMPORTANT:
Spreading the differential housing with a differential case
spreader is a step which is critical to set up bearing pre-load
when a differential is installed. Improper pre-load will result in
undue bearing wear, increased stresses in the differential center,
increased running noise, and ultimately, ring and pinion gear
damage.
c Unbolt and remove the bearing cap(s).
c Carefully spread the differential housing (Fig.3.) just enough to
remove the differential carrier (Refer to your vehicle’s service
manual).
NOTE : Never spread the housing more than 0.5mm [0.020”].
c Once the housing has been adequately spread, the differential may
be removed by pulling forward on the differential center.
Figure 3.
c With the differential center removed, relieve all tension on the
housing spreader.
