2 Removing the Existing Differential

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 caps from the differential housing.
HINT : Be sure not to mix up the left and right hand bearing
caps. Later it will be necessary to know which cup
came from which bearing and which shim came from
which side.
c Carefully spread the housing (Fig.3.) enough to remove the
differential center. (Refer to your vehicle’s service manual).
NOTE : Do not spread the housing more than 0.50mm
[0.020”].
c Once the housing has been adequately spread, the differential may
be removed by pulling forward on the differential carrier.
Figure 3.
NOTE : Keep the shims separated so that they can be
identified as to which end of the differential they came
from.
c Immediately release all spreader tension once the differential
center has been removed.
