Removing the Differential Center
IMPORTANT:
SPREAD THE HOUSING FOR REMOVAL AND INSTALLATION OF
DIFFERENTIALS (IF APPLICABLE)
Spreading the differential housing with a differential case
spreader is a step which is critical to set up bearing pre-load
on cast iron differential housings (See Figure 3.). 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.
Unbolt and remove both bearing caps from the differential housing.
HINT : Be sure not to mix up the left and right hand bearing
cups. Later it will be necessary to know which cup
came from which side.
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”].
Once the housing has been adequately spread, the differential may
be removed by pulling forward on the differential carrier.
Figure 3.
NOTE :
The differential center is heavy and quite difficult to
handle when covered in oil. Take care not to drop it.
Relieve any tension on the spreader immediately after the
differential has been removed.
