ADJUSTMENT
1. Loosen stop lamp switch and ASCD cancel switch (or brake
switch) by turning it counterclockwise by 45°.
2. Loosen lock nut (A) on input rod, then rotate input rod to set
pedal to the specified height, and tighten lock nut (A).
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch and
ASCD cancel switch (or brake switch) until its threaded end con-
tacts stopper rubber.
4. With the threaded end of stop lamp switch and ASCD cancel
switch (or brake switch) contacting stopper rubber, rotate switch
clockwise by 45° to secure.
CAUTION:
Make sure that the clearance (C) between stopper rubber
and threaded end of stop lamp switch and ASCD cancel
switch (or brake switch) is within the standard.
5. Check pedal play.
CAUTION:
Make sure that stop lamps go off when pedal is released.
6. Start engine to check brake pedal depressed height.

TOTAL PRELOAD INSPECTION
1. Turn companion flange in both directions 20 times or more to set
bearing rollers, then check total preload with special service tool.

If the preload value is out of standard, adjust by changing side
bearing adjusting shim thickness (side retainer side).
–If preload value too large, increase the side bearing adjusting
shim thickness.
–If preload value too small, decrease the side bearing adjusting shim thickness.
DRIVE PINION PRELOAD ADJUSTMENT
Removal of differential case assembly
1. Unfasten the retainer tab using a flat blade screwdriver.
2. Remove the retainer by pulling it and tapping carrier case using a plastic hammer.
3. Remove the differential case assembly from the carrier case.
CAUTION:
Be careful not to damage the carrier cover mating surface.
Removal of drive pinon assembly
1. Hold the companion flange using cam sprocket wrench or flange
wrench, remove the drive pinion lock nut.
2. Remove the companion flange using puller.
3. Temporarily install drive pinion lock nut.
CAUTION:
Avoid damaging drive pinion threads, install the drive pinion lock nut unit it flash with drive pinion
end.
4. Remove the drive pinion from the carrier case using a copper hammer.
Preload Adjustment
1. Install drive pinion adjusting washer and drive pinion bearing adjusting washer onto the drive pinion, then
install drive pinion into the carrier case.
CAUTION:
Install the removed pinion height adjusting washer and drive pinion bearing adjusting washer or
same thickness washers to drive pinion.
2. Apply gear oil to the bearing portion.
3. Install drive pinion and drive pinion bearing into the carrier case.
4. Install the companion flange without installing oil seal.
5. Apply oil to drive pinion nut threads and seating surface, then temporarily install it.
6. Turn companion flange several times to seat the bearing.
7. Tighten the drive pinion nut while measuring preload using preload gauge.
8. Select drive pinion adjusting washer and drive pinion bearing adjusting washer so that standard preload is
obtain when the drive pinion nut is tightened to specified torque.Tool number : ST3127S000 (see J25765-A)
Total preload (without oil seal)
: 1.56 - 2.65 N·m
(0.16 - 0.27 kg-m, 14 - 23 in-lb)
