Turn the 8 mm nut and
check
the pinion gear turns
smoothly and
quietly without binding.
If
the pinion gear does not turn smoothly or quietly,
the pinion gear, ring gear or bearing may be dam-
aged or
faulty.
They
must be checked after disas-
sembly; replace them
if
necessary.
BACKLASH INSPECTION
Hold
the pinion gear with the 8 mm
nut.
Set
the
differential case into a jig or vise wi
th
soft

Remove the oil filler
cap
and set a horizontal type
dial
indicator
on the ring gear through the filler
hole.
Turn the ring gear back and forth to measure the
backlash.

Remove the dial
indicator.
Turn

ring
gear 120

and
measure
backlash. Repeat this procedure once
more. Compare the difference of the three measure-
ments.
SERVICE
LIMIT:
0.2
mm (0.01 in)
If
the difference in measurements exceeds the
ser-
vice limit,
it
indicates that
the
bearing is not
installed squarely. or the case is
deformed.
Inspect
the bearings and case.
If the backlash
is
excessive. replace the ring gear left
side shim
with
a
thinner one.
If the backlash
is
too small. replace the ring gear left
side shim
with a thicker one.
The backlash is
changed
by about 0.06 mm
(0.002
in)
when the thickness of the shim
is changed
by
0.10 mm
(0.004 in).

Twenty-three different thickness shims are
