19. ADJUST DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the drive pinion
using the backlash between the drive pinion and ring gear.
Preload (at starting):
New bearing
1.3 ± 1.9 N´m (13 ± 19 kgf´cm, 11.4 ± 16.7
in.´lbf)
Reused bearing
0.8 ± 1.1 N´m (8 ± 11 kgf´cm, 7.0 ± 9.7 in.´lbf)
If the preload is greater than the specified value, replace the
bearing spacer.
If the preload is less than the specified value, retighten the nut
with a force of 13 N´m (130 kgf´cm, 9 ft´lbf) until the specified
preload is reached.
Torque: 451 N´m (4,600 kgf´cm, 333 ft´lbf) or less
If the maximum torque is exceeded while retightening the nut,
replace the bearing spacer and repeat the preload procedure.
Do not loosen the pinion nut to reduce the preload.
20. CHECK TOTAL PRELOAD
Using a torque wrench, measure the total preload with the teeth
of the drive pinion and ring gear in contact.
Total preload (at starting):
Drive pinion preload plus 0.4 ± 0.6 N´m (4 ± 6 kgf´cm,
3.5 ± 5.2 in.´lbf)
21. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash.
Backlash: 0.13 ± 0.18 mm (0.0051 ± 0.0071 in.)
22. RECHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See step 13.)

HINT:
Perform the following before installation.
When using safety stands and jack:
(1) Jack up the rear axle until the bottom of the rear
pneumatic cylinder touches the rear axle and fit the
seating pin on the lower side of the rear pneumatic
cylinder into the rear axle.
NOTICE:

Do not extend the rear pneumatic cylinder in order to
fit the seating pin into the hole.

Make sure that the seating pin on the lower side of the
rear pneumatic cylinder fits in the hole in the rear
axle.
(2) Remove the safety stands with care not to extend
the rear pneumatic cylinder when jacking down the
vehicle till it sits on the ground.
NOTICE:
Make sure that the diaphragm (rubber part) of the pneumat-
ic cylinder is not deformed.
(3) Start the engine and replenish the rear pneumatic
cylinder with air.
(e) When using a swing arm type lift:
(1) Lower the vehicle till the tires hit the ground, and
continue lowering slowly until the bottom of the rear
pneumatic cylinder touches the rear axle.
(2) Align the seating pin on the cylinder with the hole in
the rear axle and install the rear pneumatic cylinder
on the rear axle.
NOTICE:

Do not extend the rear pneumatic cylinder by lifting
up the rear axle housing after fitting the seating pin.

Make sure that the diaphragm (rubber part) of the
pneumatic cylinder is not deformed.
(3) Lower the lift carefully so as not to extend the rear
pneumatic cylinder.
NOTICE:
Make sure that the diaphragm (rubber part) of the pneumat-
ic cylinder is not deformed.
(4) Start the engine and replenish the rear pneumatic

BRAKE PEDAL
ON±VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
151.1 ± 165.1 mm (5.949 ± 6.500 in.)
NOTICE:
Do not adjust the pedal height. Doing so by changing the
push rod length of the brake booster will structurally
change the pedal ratio.
If the pedal height is incorrect, check that there is no damage
in brake pedal, brake pedal lever, brake pedal bracket and dash
panel.

Even if there is damage, there is no problem if the
reserve distance is within the standard value.

If necessary, replace them.
2. IF NECESSARY, ADJUST STOP LIGHT SWITCH
(a) Remove the front door scuff plate, cowl side trim, side
panel, lower finish panel and No. 2 heater to register duct
(See page BO±89).
(b) Loosen the stop light switch lock nut.
(c) Push the brake pedal in 5 ± 15 mm (0.20 ± 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(d) Push the brake pedal in 5 ±15 mm (0.20 ± 0.59 in.), check
that the stop light lights up.
(e) Install the No. 2 heater to register duct, lower finish panel,
side panel, cowl side trim and front door scuff plate (See
page BO±89).
3. CHECK PEDAL FREE PLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the second point of resis-
tance begins to be felt, then measure the distance as
shown in the illustration.
Pedal free play: 1 ± 6 mm (0.04 ± 0.24 in.)
HINT:
The free play to the first point of resistance is due to the play
between the clevis and pin. It is 1 ± 3 mm (0.04 ± 0.12 in.) at the
pedal.
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance:
0.5 ± 2.4 mm (0.020 ± 0.095 in.)
