1. Block the front wheels, raise the left rear wheel. and
support it with a safety stand as shown.
Hold the tire and turn it counterclockwise continu-
ouslv for more than one rotation.
lf the rotation of the wheel does not gradually
feel heavy while rotating, the 2WD system when
decelerating in a forward gear is normal.
lf the rotation of the wheel gradually feels heavy,
there is a problem in the system. Check the dif-
ferential fluid, lf the fluid is normal, reDlace the
toroue control differential case kit.

Troubleshooting
Most problems in the unit are to be diagnosed by identifying noises from the gears or bear'ngs'
care should be taken during diagnosis not to confuse differential noises with those from other drivetra'n components'

Maintenance
Differential Fluid
!@ Make sure lifts are placed properly lseesection 1).
1. With the vehicle on level ground, inspect differential
fluid with engine OFF.
2. Remove the oil filler plug, then check the level andcondition of the fluid.
Proper Level
o|I FII.IIR PI-UG4t N.m la.8 kgl.m, 35 lbl.ftl
The fluid level must be up ro the fill hole. lf it isbelow the hole, add the recommended fluid until itruns out, then reinstall the oil filler plug with a new
wasner.
lf the differential tluid is dirty, remove the drainplug, and drain the fluid.

Clean the drain plug, then reinstall it with a new
washer, and refill the differential with the recom-
mended fluid to the proper level.
NOTEr lf you disassembly the differential, check thefluid level again after the 4WD system check is fin-
ished. Add fluid if necessary.
Reinstall the oil filler plug with a new washer.
