Assembly and Installation
52 MAINTENANCE MANUAL
A. Install four capscrews and washers or bolts,
nuts and washers into the case halves. The
distance between the fasteners must be
equal. Tighten the fasteners to the correct
torque value in a crisscross pattern opposite
each other. See the Section 8. Figure 5.26.
B. Install the other fasteners into the case
halves. Tighten the fasteners to the correct
torque value. See Section 8.
16. Check the rotating resistance of the differ-
ential gears. The differential assembly must
rotate freely.
Check the Rotating Resistance of the
Bearing of Case Halves Assembly
1. Make an inspection tool using an axle shaft
that matches the spline size of the differen-
tial side gear. Cut the shaft to approximately
12-inches (304.8 mm). Weld a nut onto the
end of the shaft. Figure 5.27.
2. Place the case halves ensembly and ring gear
into a vise. Install soft metal covers over the
visejawstoprotecttheringgear.Figure5.28.
3. Install the tool into the differential until the
splines of the tool are engaged with one side
gear. Figure 5.28.
4. Place a torque wrench onto the nut of the tool
and rotate the differential gears. As the differ-
ential gears rotate, read the value indicated
on the torque wrench. Figure 5.29..
• If the torque value exceeds 50 lb-ft (67.8
N.m), disassemble the gears from the case
halves. Inspect the case halves, spider,
gears and thrust washers. Repair or replace
parts. Assemble the parts and repeat Step 2
through Step 4.
