llA0065SERVICE ADJUSTMENT PROCEDURES
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.

CHECKN03FEAE
(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.

IncorrectREAR WHEEL BEARING ROTATION SLIDING
RESISTANCE CHECKNOOFJAA
(1) Remove the drive shaft from the companion flange.
(2) Remove the brake pad or caliper assembly.
(3) Attach a spring balance to the hub bolt, then, pulling the
balance at a right angle to the hub bolt, measure the
rotation sliding resistance (rotation starting torque) to see
whether it is within the standard value.
Standard value: 12
N (2.6 Ibs.) [rotation starting tor-
que 0.7 Nm (6 in
Ibs.)] or less
(4) If the rotation starting torque exceeds the standard value,
check the tightening torque of the axle shaft companion
flange. If it is normal, replace the bearing.
LIMITED-SLIP DIFFERENTIAL CHECKNOJFIAA(1) Block the front wheels and move the shift lever to neutral.
(2) Completely release the parking brake.
(3) Jack up the rear wheels and place a rigid rack at the
specified part of the side sill.
(4) Disconnect the coupling of the differential and propeller
shaft.(5) When one wheel is slowly rotated, check whether or not
the wheel on the other side turns in the same direction.
(6) If it turns in the opposite direction, replace the viscous unit.

_ CAUTION
When servicing brake assemblies or components, do not create dust by sanding, grinding or by cleaning
brake parts with a dry brush or with compressed air. A WATER DAMPENED CLOTH SHOULD BE USED.
Many brake components contain asbestos fibers which can become air-borne if dust is created duringservice operations. Breathing dust which contains asbestos fibers can cause serious bodily harm.
