Brake Linings and Drums
2) Check the disk rotor for wear, dents or other
damage. If the inside surface of disk rotor is
streaked, correct the surface with emery cloth
(#200 or more). If it is unevenly worn or tapered,
correct or replace it.
Brake drum inside diameter
Standard value: 170 mm (6.69 in)
Wear limit: 171 mm (6.73 in)
3) If the deformation or wear of back plate, shoe,
etc. is noticeable, replace them.
4) When the shoe return spring tension is exces-
sively weakened, replace it.B: ADJUSTMENT
1. REAR DRUM BRAKE
The main brake is adjusted automatically, and so
there is no need to adjust it.
2. PARKING BRAKE (REAR DISC BRAKE)
For rear disc brake, adjust the parking brake after
bleeding air.
1) Remove the rear cover (rubber) installed at back
plate.
2) Turn the adjuster toward arrow mark (upward)
until it is locked slightly, by using a flat tip screwdriv-
er as shown in illustration.
3) Turn back (downward) the adjuster 3 to 4 notch-
es.
4) Install the rear cover (rubber) at original position
correctly.

Suspension
22.Suspension
A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out.
If relative movement (B) is observed between the
brake disc cover (A) and end of transverse link (D),
ball joint (C) may be excessively worn.
3) Grasp the end of transverse link (C) and move it
up and down. Relative movement (A) between the
housing (D) and transverse link boss indicates ball
joint (B) may be excessively worn.
4) If relative movement is observed in the immedi-
ately preceding two steps, remove and inspect the
ball joint. If free play exceeds standard, replace the
ball joint.
5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the transverse link. Front Transverse Link.> And measure free play of
ball joint.
(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with the
new ball joint.
NOTE:
When the transverse link ball joint has been re-
moved or replaced, check the toe-in of front wheel. If the front wheel toe-in is not at specified value, ad-
just the toe-in.
2. TRANSVERSE LINK’S REAR BUSHING
Check oil leaks at around liquid-filled bushing. If oil
leaks, replace the bushing.
3. WHEEL ARCH HEIGHT
1) Unload cargoes and set the vehicle in curb
weight (empty) condition.
2) Then, check the wheel arch height of front and
rear suspensions to ensure that they are within
specified values.
3) When the wheel arch height is out of standard,
visually inspect the following components and re-
place deformed parts.
 Suspension components [Front strut assembly
and rear strut assembly]
 Parts connecting between suspension and body.
4) When no components are deformed, adjust the
wheel arch height by replacing coil spring in the
suspension which wheel arch height is out of stan-
dard. RS-8, Wheel Alignment.>

6. OIL LEAKAGE OF STRUT
Visually inspect the front strut and rear strut for oil
leakage as instructed. If oil leakage reaches under
spring seat lower portion, replace the front strut and
rear strut.
7. TIGHTNESS OF BOLTS AND NUTS
Check the bolts and nuts shown in the figure for
looseness. Retighten the bolts and nuts to speci-
fied torque. If the self-lock nuts and bolts are re-
moved, replace them with new ones.

8. DAMAGE TO SUSPENSION PARTS
Check the following parts and the fastening portion
of the vehicle body for deformation or excessive
rusting which impairs the suspension. Remove the
contaminations on spring seat lower portion with
care because dirt, sand, etc. tend to accumulate on
it. If necessary, replace the damaged parts with
new ones. If minor rust formation, pitting, etc. are
noted, remove the rust and apply remedial anti-cor-
rosion measures.

Steering)
A: INSPECTION
1. STEERING WHEEL
1) Set the steering wheel in a straight-ahead posi-
tion, and check the wheel spokes to make sure
they are correctly set in their specified positions.
2) Lightly turn the steering wheel to the right and
left to determine the point where front wheels start
to move.
Measure the distance of the movement of steering
wheel at the outer periphery of wheel.
Steering wheel free play:
0 — 17 mm (0 — 0.67 in)
Move the steering wheel vertically toward the shaft
to ascertain if there is play in the direction.
Maximum permissible play:
0.5 mm (0.020 in)
3) Drive the vehicle and check the following items.
(1) Steering force:
The effort required for steering should be
smooth and even at all points, and should not
vary.
(2) Pull to one side:
Steering wheel should not be pulled to either
side while driving on a level surface.
(3) Wheel runout:
Steering wheel should not be runout.
(4) Return factor:
Steering wheel should return to its original posi-
tion after it has been turned and then released.
2. STEERING SHAFT JOINT
When the steering wheel free play is excessive,
disconnect the universal joint of steering shaft and
check it for any play and yawing torque (at the point
of the crossing direction). Also inspect for any dam-
age to sealing or worn serrations. If the joint is
loose, retighten the mounting bolts to the specified
torque.
Tightening torque:
24 N·m (2.4 kgf-m, 17.4 ft-lb)
3. GEARBOX
1) With wheels placed in the direction of straight
ahead, turn the steering wheel 90° in both the right
and left directions.
While the steering wheel is being rotated, check for
looseness in gearbox.
Tightening torque:
59 N·m (6.0 kgf-m, 43.4 ft-lb)
2) Check the boot for damage, cracks or deteriora-
tion.
3) With the vehicle on a level surface, quickly turn
the steering wheel to the right and left.
While the steering wheel is being rotated, check the
gear backlash. If any unusual noise is noticed, ad-
just the gear backlash in the following manner.
(1) Tighten the adjusting screw to 7.4 N·m (0.75
kgf-m, 5.4 ft-lb) and then loosen. Repeat this op-
eration twice.

Hold the adjusting screw with a wrench to pre-
vent it from turning it, while tightening the lock
nut.
4. TIE-ROD
1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.
2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If the castle nut is loose, re-
tighten it to the specified torque, then tighten further
up to 60° until the cotter pin hole is aligned.
Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)3) Check the lock nut on tie-rod end for tightness. If
it is loose, retighten it to the specified torque.
Tightening torque:
83 N·m (8.5 kgf-m, 61.5 ft-lb)
5. POWER STEERING FLUID LEVEL
NOTE:
 Check at power steering fluid temperature 20°C
(68°F); read the fluid level on the “COLD” side.
 Check at power steering fluid temperature 80°C
(176°F); read the fluid level on the “HOT” side.
1) Place the vehicle with engine stopped on a flat
and level surface.
2) Check the fluid level using the scale on the out-
side of reservoir tank (A). If the level is below “MIN”
(B), add fluid to bring it up to “MAX” (C).
NOTE:
If the fluid level is at “MAX” level or above, drain flu-
id to keep the level in specified range of indicator by
using a syringe or the like.
Recommended fluid:
Dexron III
Fluid capacity:
0.72 (0.7 US qt, 0.6 Imp qt)
6. POWER STEERING FLUID FOR LEAKS
Inspect the underside of oil pump and gearbox for
power steering system, hoses, piping and their
couplings for fluid leaks.
If fluid leaks are found, correct them by retightening
their fitting bolts (or nuts) and/or replacing their
parts.
CAUTION:
 Wipe the leakage fluid off after correcting flu-
id leaks, or a wrong diagnosis is taken later.
 Also pay attention to clearances between
hoses (or pipings) and other parts when in-
specting fluid leaks.
