REAR AXLE TOTAL BACKLASH CHECK
N03FAAF
If the vehicle vibrates and produces a booming sound due to animbalance of the driving system, measure the rear axle total
backlash by the following procedures to see if the differential
carrier assembly required removal.
(1) Place the gearshift lever in the neutral position, apply the
parking brake and jack up the vehicle.
(2) Manually turn the propeller shaft clockwise as far as it will
go and make mating marks on the companion flange dust
cover and the differential carrier.
(3) Manually turn the propeller shaft counterclockwise as far as
it will go and measure the movement of the mating marks.Limit: 5 mm
(.2 in.)
(4) If the backlash exceeds the limit, remove the differential
carrier assembly and adjust the backlash. (Refer to P.3-20.)
GEAR OIL LEVEL CHECKN03FCAA1. Remove the filler plug, and check the oil level.
2. The oil level is sufficient if it reaches the filler plug hole.

(1) Support the vehicle on axle stands positioned at the
specified locations and remove the rear wheel.
(2) Separate the parking brake cable from the rear brake.
(3) Remove the caliper assembly and brake disc.
(4) Place a dial gauge as shown in the figure, and then
measure the play when the axle shaft is moved in the axial
direction.Limit: 0.8 mm
(.031 in.)
(5) If the play exceeds the limit, check the tightening torque of
the companion flange of the axle shaft; if it is correct,
replace the wheel bearing.

Caution
1.Be cautious to ensure that the differential carrier oil
seal is not damaged by the drive shaft spline.
2. The drive shafts for models equipped with the
limited-slip differential are of different length and,
in addition, the right drive shaft has a two-part
serration; be very careful to install each one on the
correct side.
NOTE
The left and right drive shafts can also be distinguishedfrom each other by the identification color of boot band

3.Be sure to thoroughly remove any oil or grease, etc.from the threaded part of the bolt and nut used for
installation to the companion flange,
because any
oil, grease, etc. on these parts might cause later
loosening even though tightening is at the specifiedtorque.
