Control Cable AdjustmentNCAT0111Move selector lever from the ªPº position to the ªLº position. You
should be able to feel the detents in each position. If the detents
cannot be felt or if the pointer indicating the position is improperly
aligned, the control cable needs adjustment.
1. Place selector lever in ªPº position.
2. Loosen control cable lock nut and place manual shaft in ªPº
position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park lock.
3. Tighten control cable lock nut.
:12-14N×m (1.2 - 1.5 kg-m,9-10ft-lb)
4. Move selector lever from ªPº to ªLº position again. Make sure
that selector lever moves smoothly.
5. Apply grease to contacting areas of selector lever and control
cable. Install any part removed.
Park/Neutral Position (PNP) Switch AdjustmentNCAT01121. Remove control cable end from manual shaft.
2. Set manual shaft in ªNº position.
3. Loosen PNP switch fixing bolts.
4. Usea4mm(0.157 in) pin for this adjustment.
a. Insert the pin straight into the manual shaft adjustment hole.
b. Rotate PNP switch until the pin can also be inserted straight
into hole in PNP switch.
5. Tighten PNP switch fixing bolts.
: 4.9 - 6.8 N×m (0.5 - 0.7 kg-m, 44 - 60 in-lb)
6. Remove pin from adjustment hole after adjusting PNP switch.
7. Reinstall any part removed.
8. Adjust control cable. Refer to ªControl Cable Adjustmentº.
9. Check continuity of PNP switch. Refer to AT-53.
Differential Side Oil Seal ReplacementNCAT01131. Remove drive shaft assemblies. Refer to FA section (ªDrive
Shaftº, ªFRONT AXLEº).
2. Remove oil seals.

Precautions
lWhen installing each rubber part, final tightening must
be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lWhen removing each suspension part, check wheel
alignment and adjust if necessary.
lUse Tool when removing or installing brake tubes.
lAlways torque brake lines when installing.
