FRONT DRIVING MECHANISM (FM/FE models)
DIFFERENTIAL

They must be checked after disassembly; replace
them if necessary.

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 read backlash.
STANDARD:
SERVICE LIMIT:
Remove the dial indicator. Turn the ring gear 120°
and measure backlash. Repeat this procedure once
more.
Compare the difference of the three measurements.
SERVICE LIMIT:
If the difference in measurements exceeds the
service 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.
Backlash changed by about 0.06 mm (0.002 in)
when thickness of the shim is changed by 0.10 mm
(0.004 in).
