2 Front Differential Carrier Assembly
Warning

If the bearings are not properly seated into the bearing cups, the washer selection will be inaccurate and the bearing pre-load will be set too low. Low bearing pre-load will cause premature failure of the front differential drive pinion gear.


Rotate the differential assembly 10 revolutions to allow the bearings to seat into the cups.
Note

Differential rotating tool DT-47793 differential rotating tool can be used to rotate the differential from the case side.

Differential Thrust Washer Selection


Differential Thrust Washer Selection

Callout Component Name
Warning

Improper thrust washer selection can cause insufficient taper bearing pre-load which will cause premature failure of the front differential drive pinion gear.


1 Front Differential Bearing Washer

Procedure

Place DT 47800-7 in the gap in DT 47800-2 which are both part of DT-47800 selection gauge kit , to determine the proper thrust washer. Choose the correct thrust washer. Refer to Taper Bearing Preload Selective Specifications .
Note
Continue trying different sizes of DT 47800-7 which is part of DT-47800 selection gauge kit , until the gauge will no longer fit into the gap. The correct thrust washer size is equal to the largest blade gauge that fits into the gap.

Match the size of the correct DT 47800-7 blade which is part of DT-47800 selection gauge kit , to the color code in the thrust washer specification chart. The washer color coding is on the outside diameter of the washer.

The gap in DT 47800-2 which are both part of DT-47800 selection gauge kit may not be even. Hold the top of the gauge and rotate the bottom of the gauge to even out the gap. Take two gap measurements 180 degrees apart. Average the two measurements and select the thrust washer that is closest to the average.

The washer color coding is on the outside diameter of the washer.
