4B1–5 DRIVE LINE CONTROL SYSTEM (SHIFT ON THE FLY)
4. If vacuum is not applicable as much as –400mmHg,
and if there is resistance on the intake side, replace
with a new check valve.
VSV Assembly
Inspect the vehicle side harness as follows:
412RS071
Legend
(1) Grey
(2) Blue
1. Remove connector.
2. Shift transfer lever to 2H and start the engine.
NOTE: Do not move the vehicle while inspection.
3. Make sure that there is continuity in the vehicle side of
harness. If there is no continuity, check transfer shift
switch and wiring.
Inspect both VSVs as follows:
F04RS004
1. With battery not connected (Usual).
A–C:There is continuity
B:Closed
2. With battery connected
A – B:There is continuity
C:Closed
3. If 1) and 2) fail, replace with a new VSV.
Axle Position Switch
412RS048
1. With ball (1) being free
A – B:There is continuity
2. With ball forced into the switch
A – B:No continuity
3. If 1) and 2) fail, replace with a new switch.

Motor Actuator Assembly
Inspect the function of the motor actuator assembly as
follows:

4C–45 DRIVE SHAFT SYSTEM
Universal Joint Reassembly
1. Install spider to flange yoke. Be sure to install the
spider by aligning the setting marks made during
disassembly.
2. Apply a molybdenum–disulfide grease or a
multi–purpose type grease NLGI No. 2 to inside of the
bearing cap.
Grease Amount: Approx. 1.2 g (0.042 oz)
401RS011
3. Using either a mallet (or copper hammer) or a press,
install the needle roller bearing into the yoke so that
the snap ring can be installed in its groove.
CAUTION: The needle roller bearing cannot be
installed smoothly if it is set at an incorrect angle
with the flange and excessive hammering will
damage the needle roller bearing.
401RS012
4. Align setting marks (1) and join the yokes.
401RS028
5. Install snap ring.
NOTE: Discard used snap rings and install new ones.
When the bearing cap is in position, select and attach a
snap ring of suitable thickness so that the end play of the
spider pin is held within 0.1 mm (0.004 in).
Snap ring thickness and Identification color
1.5 mm (0.059 in); Blue
1.53 mm (0.060 in); White
1.59 mm (0.063 in); Yellow
