Caution
When pressing in, apply a solution of soap and water to
the sliding part of the bushings, and then press them inwithout stopping one after the other.
If there is a pause during the pressing operation, the
frictional resistance will prevent installation.

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.
Specified gear oil:
MOPAR Hypoid Gear Oil API classification
GL-5 or
higher
[0.7 liter (0.74 qts.)]

8OW-90Below
-34°C (-30°F): SAE 75WREAR WHEEL BEARING END PLAY
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.
