1. REAR AXLE TOTAL BACKLASH CHECK

If the drive system roars or the vehicle vibrates, use the
following procedure to measure total backlash in the rear
axle. Based on the measurement taken, determine whether
the differential carrier assembly needs to be removed or not.
(1) Place the shift lever in the neutral position and operate
the parking brake.
(2) Turn the propeller shaft fully clockwise and make an
alignment mark on the companion flange dust cover and
gear carrier.
(3) Turn the propeller shaft fully counterclockwise and
measure the deviation between the alignment marks.
Limit: 5 mm
(4) If the backlash exceeds the limit, replace the differential
carrier assembly.

2. GEAR OIL LEVEL CHECK

2-1 DIFFERENTIAL
(1) Remove the filler plug.
(2) Check that the gear oil level is within the specified range
from the bottom end of the filler plug hole.
Standard value (A): 6 mm
(3) If the gear oil level exceeds the standard value, add the
specified gear oil up to the bottom end of the filler plug
hole.
Specified gear oil:
MITSUBISHI
