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.

 Unbolt and remove the bearing caps.

HINT : Be sure not to mix up the left and right hand tapered

roller bearing cups or pre-load shims. Later it will be

necessary to know which cup came from which bearing

and which shim came from which side.

 Carefully spread the differential housing (Fig. 3.) just enough to

remove the differential center (Refer to your vehicle’s service manual).

NOTE : Never spread the housing more than 0.5mm [0.02”].

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

removed by pulling forward on the differential center.

Figure 3.

NOTE : The differential center is heavy and quite difficult to

handle when covered in oil. Do not drop it!
