2. On 46, 48000 remove two dif-
ferential carrier mounting nuts,
one on each side of the lowest
nut. Install two special flat wash-
ers over studs, then install Rear
Bracket J-8973-16 with bent edge
toward front and slot to the right,
using nuts just removed. Qn 45000
install bracket as shown in Fig-
ure 6-114.
3. Take cable assembly and hook
Front A t t a c h i n g B r a c k e t
J-8973-15 over c e n t e r of front
frame cross member. Pull cable
tight and position cable all-the-
way in slot of rear bracket so one
of the stops is to the rear of the
bracket.
4. Position Engine Height Plate
J-8973-14 vertically with wide
end centered against front flange
of engine pan. Pull cable down
and place in lower notch of plate.
See Figure 6-114.
5. M e a s u r e perpendicular dis-
tance from machined surface im-
mediately in front of slinger on
rear pinion flange to top of cable.
This distance is given for 45-46-
48000 models in Figure 6-114.
b. Adjusting Rear Universal
Joint Angle
If the distance measured in Step
5 above was not correct, the pin-
ion nose must be moved up or
down as required. This is done
by shimming the upper control
arms.
Adjust rear universal joint angle
using the following procedure:
1. Place a jack under pinion
nose. Because of the geometry of
the rear suspension, the pinion
nose will tend to move downward
when released and must be held
upward.
2. Loosen nuts and bolts retain-
ing upper control arm brackets to
frame. See Figure 6-113.
3. Using jack, raise or lower
pinion nose as required to get
correct measurement from pin-
ion flange to top of cable.
4. Install shims as required be-
tween brackets and frame. See
Figure 6-113.
5. Lower jack from under pinion
nose and retorque bracket to
frame attaching nuts and bolts to
25-35 ft. lbs. Recheck measure-
ment on Kentmore set-up. If di-
mension is off, loosen bracket to
frame nuts and bolts and repeat
preceding steps to obtain correct
reading.
6. Remove all parts of the align-
ment set, being careful to avoid
kinking cable in handling and
storing.
