Replacement
1. Raise rear of vehicle and place stand jacks under
frame side rails so that axle hangs freely to allow
sufficient working room.
2. Check wheels for freedom of rotation.
3. Separate rear universal joint, tape trunnion bearings
to joint, position propeller shaft to one side and tie it
to frame side rail.
4. Using Tool J-5853 with Adapter J-5810 and a suitable
socket on the pinion flange nut, rotate the pinion
through several complete revolutions and record the
torque required to keep the pinion turning (fig. 46).
If flange is to be reused, mark pinion and flange for
reassembly in the same relative position.
5. Install Tool J-8614-1 on pinion flange and remove
pinion flange nut (fig. 47). (Position J-8614-1 on
flange so that the four notches are toward flange.)
Discard nut and use a new one upon reassembly.
6
. Thread pilot end of Tool J-8614-3 into small O.D.
end of J-8614-2. Then with J-8614-1 installed as in
Step 4, insert J-8614-2 into J-8614-1 and turn it 45
degrees to locked position. Remove flange by turn­
ing J-8614-3 while holding J-8614-1 (fig. 48).
7. Pry old seal out of bore, using a screwdriver or a
hammer and chisel.
8
. Inspect pinion flange for smooth oil seal surface,
worn drive splines, damaged ears, and for smooth­
ness of
bearing contact surface. Replace if
necessary.
9. If deflector requires replacement, remove by tapping
from flange, clean up stake points; install new de­
flector, and stake deflector at three new equally
spaced positions.
