SERVICE ADJUSTMENT PROCEDURES
REAR AXLE TOTAL BACKLASH CHECK
If the vehicle vibrates and produces a booming sound due to an
imbalance of the driving system, measure the rear axle total
backlash by the following procedures to see if the differential
carrier assembly requires 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 in.)
(4) If the backlash exceeds the limit, remove the differential
carrier assembly
and
adjust the backlash. (Refer to
