Measure
1. The distance from the side gear face to the case
half face (figure 16).
A. The thickness of the straight edge must be sub­
tracted from the reading.
B. Add the measurement of both sides together.
This is the side gear spread.
2. The thickness of the original reaction blocks and
reaction block thrust washers together (figure 17).
3. If the combined reaction block and thrust washer
thickness is not 0.000 to 0.1524 mm (0.000 to
0.006 inch) less than the side gear spread, adjust
the clearance by:
• Selecting new reaction block thrust washer of
the correct thickness to obtain 0.000 to 0.1524
mm (0.000 to 0.006 inch) clearance.
• Reshim the left and/or right clutch disc pack.
The side gear backlash must be maintained.
Refer to “ Right Side” and/or “ Left Side Gear
Backlash Adjustment” in this section.
• Some older locking differentials had select
fit reaction blocks without the thrust washer
between them. These models require replac­
ing the reaction blocks with the correct thick­
ness reaction block.
