2 Removing the Existing Differential

2.6

Removing the Differential Center

IMPORTANT:

YOU MUST SPREAD THE HOUSING ON CAST IRON 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 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.

 Remove both bearing caps.

 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.

 Once the housing has been adequately spread, the differential may

be removed by pulling forward on the differential carrier.
