2.6 Removing the Differential Center
IMPORTANT:
YOU
MUST SPREAD THE HOUSING ON DANA 35 MODELS
Spreading the differential housing with a differential case
spreader is a step which is critical to set up bearing pre-load on
cast iron Dana 35 differential housings. 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 Remove both bearing caps.
c Carefully spread the housing (Fig.5.) 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”].
NOTE : Be sure not to mix up the left and right hand bearing
cups and master shims. Later it will be necessary to
know which cup and shim came from which side.
c Once the housing has been adequately spread, the differential may
be removed by pulling forward on the differential carrier.
Figure 5.
NOTE : The differential center is heavy and quite difficult to
handle when covered in oil. Take care not to drop it.
c Relieve any tension on the spreader immediately after the
differential has been removed.
