e)
Use tool (E) and a torque wrench to
measure the torque required to turn
the pinion shaft. Record this torque
measurement.
f)
While turning bevel gear (51), use tool
(D), and tighten the bearing adjuster
nut on the side adjacent to the bevel
gear until there is zero backlash.
g)
Loosen the bearing adjuster nut to the
nearest position where the bearing
adjuster nut lock can be installed (maxi-
mum of one lug movement).
h)
Use tool (D), and tighten the bearing
adjuster nut on the side opposite the
bevel gear until the torque required to
turn the pinion shaft increases to 0.2
to 0.5 N-m (2 to 4 lb. in.) more than the
torque measurement recorded in Step e.
i)
Put an alignment mark on bearing cap
(46) adjacent to one of the lugs on bear-
ing adjuster nut (48).
j)
Put an alignment mark on bearing
adjuster nut (48) three lugs counter-
clockwise from the mark on bearing cap
(46).
k)
Tighten bearing adjuster nut (48) until
the two marks are in alignment. If the
bearing adjuster nut lock cannot be
installed, tighten adjuster nut (48) until
the lock can be installed.
I)
Use tool (C), and measure the backlash
between the bevel gear and pinion. The
backlash must be 0.20 to 0.42 mm
(.008 to .017 in.).
NOTE: The differential preload will be kept only
if one bearing adjuster nut is loosened and the
other adjuster nut is tightened the same amount.
m)
If backlash is too much, loosen bearing
adjuster nut (49), and tighten adjuster
nut (50) the same amount.
n)
If backlash is not enough, loosen bear-
ing adjuster nut (50), and tighten
adjuster nut (49) the same amount.
o) Tighten bolts (47) in bearing caps (46)
and (48) to a torque of 475 ± 50 N-m
(350 + 37 lb. ft.).
