2 Removing the Existing Differential

2.6 Removing the Differential Center
IMPORTANT:
YOU MUST SPREAD THE HOUSING
Spreading the differential housing with a differential case
spreader is a step which is critical to set up bearing pre-load
(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.
F Remove both bearing caps.
F 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”].
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.
F Once the housing has been adequately spread, the differential may
be removed by pulling forward on the differential carrier.
