1987 SUZUKI GRAND VITARA inflation pressure

Parking Brake Cable
Inspect brake cable for damage and smooth
movement. Replace cable if it is in deteriorat-
ed condition.
36. TIRE INSPECTION AND ROTATION
1) Check tires for uneven or excessive wear, or
damage. If defective, replace.
2) Check inflating pressure of each tire and
adjust pressure to specification as necessary.
NOTE:
l Tire inflation pressure should be checked
when tires are cool.
l Specified tire inflation pressure should be
found on tire placard or in owners’ manual
which came with the car.
3) Rotate tires.
For the details of above steps 1) to 3), refer
to MAINTENANCE SERVICE (p. 18-19 and
18-20) of SECTION 18.
37. WHEEL DISCS AND FREE WHEELING
HUBS (if equipped) INSPECTION
Wheel Discs
Inspect each wheel disc for dents, distortion and
cracks. A disc in badly damaged condition must
be replaced.
Free Wheeling Hub
This is applicable to the car equipped with
free wheeling hubs.
Check free wheeling hub for proper operation
by moving free wheeling hub knob to LOCK
and FREE positions. (The same check on both
right and left wheels)
For checking procedure, refer to MAINTE-
NANCE SERVICE (p. 17-29) of SECTION 17.
38. STEERING KNUCKLE OIL SEAL
REPLACEMENT
For replacement procedure, refer to MAIN-
TENANCE SERVICE (p. 17-23) of SECTION
17.
39. WHEEL BEARING INSPECTION
[Inspection of wheel bearing]
1) Check front wheel bearing for wear, damage,
abnormal noise or rattles. For the details,
refer to MAINTENANCE (p. 17-20 and
17-21) of SECTION 17.
2) Check rear wheel bearing for wear, damage
abnormal noise or rattles. For the details,
refer to MAINTENANCE SERVICE (p. 17-24)
of SECTION 17.
[Inspection of front wheel bearing grease]
1) Remove wheel hub and spindle referring to
FRONT WHEEL HUB REMOVAL of SEC-
TION 17.
2) Check grease around front wheel bearing
rollars and between front axle shaft surface
and wheel spindle bush for deterioration and
capacity.
If grease is deteriorated, remove grease tho-
roughly and apply enough amount of new
SUZUKI SUPER GREASE A or wheel bearing
grease. If grease is found insufficient, add some
more.

Camber
Camber is the tilting of the front wheels from
the vertical, as viewed from the front of the car.
When the wheels tilt outward at the top, the
camber is positive. When the wheels tilt inward
at the top, the camber is negative. The amount
of tilt is measured in degrees.

Toe Adjustment
1. Before making any adjustment affecting toe
setting, the following checks and inspections
should be made to insure correctness of
alignment readingsand alignment adjustments:
1) Check all tires for proper inflation pressures
and approximately the same tread wear.
2) Check steering and suspension system for
looseness. If excessive looseness is noted, it
must be corrected before adjusting.
3) Check for run-out of wheels and tires.
4)Consideration must be given to excess loads,
such as tool boxes. If this excess load is
normally carried in the car, it should remain
in the car during alignment checks.
5) Consider condition of the equipment being
used to check alignment and follow manufac-
ture’s instructions.
6) Regardless of equipment used to check
alignment, the car must be on a level surface
both fore and aft and transversely.
7) Check to be sure that front wheels are set in
straightforward driving position.
2. Toe is adjusted by changing tie rod length.
Loosen tie rod end lock nuts first and then
rotate turnbuckle @ to align toe-in to specifi-
cation. At this time, thread length “A” and
“B” should be equal. After adjustment,
tighten lock nuts to specified torque.

Camber and Caster Adjustment
Should camber or caster be found out of specifi-
cations upon inspection, locate its cause first. If
it is in damaged, loose, bent, dented or worn
suspension parts, they should be replaced. If it is
in chassis frame (car body), repair it so as to
attain specifications.
To prevent possible incorrect reading of camber
or caster, car front end must be moved up and
down a few times before inspection.
Reference Information:
SIDE SLIP:
For inspecting front wheel side slip with side slip
tester:
Side slip limit:Less than 3 mm/m
(Less than 0.118 in/3 ft)
If side slip exceeds this limit, toe-in or front
wheel alignment may not be correct.

[ Inflation of tires]
l Tire inflation pressures are listed on the
Tire Placard at driver’s side of instrument
panel.
l Tire inflation pressures should be checked
(including spare tire) at least monthly and
when significantly changing the load in the
car.
l Always check tire inflation pressures when
tires are “cold”.
l Always use tire pressure gauge when checking
inflation pressure.
l Be sure to reinstall tire inflation valve caps to
prevent dirt and moisture from getting into
valve core, as they may cause air leakage.
l If air loss occurs while driving, do not drive
on the deflated tire more than is needed to
stop safety. Driving even a short distance on a
deflated tire can damage a tire and wheel
beyond repair.
NOTE:
Before installing wheels, remove any build-up of
corrosion on the wheel mounting surface and
brake drum or disc mounting surface by scraping
and wire brushing. Installing wheels without
good metal-to-metal contact at the mounting
surfaces can cause wheel nuts to loosen, which
can later allow a wheel to come off while the
car is moving.

[Wheels]
Wheels must be replaced if they are bent, dented,
have excessive lateral or radial runout, leak air
through welds, have elongated bolt holes, if
lug nuts won’t stay tight, or if they are heavily
rusted. Wheels with greater runout than shown
in below figure may cause objectional vibrations.
Replacement wheels must be equivalent to the
original equipment wheels in load capacity,
diameter,rim width, offset and mounting
configuration. A wheel of improper size or type
may affect wheel and bearing life, brake cooling,
speedometer/odometer calibration, car ground
clearance and tire clearance to the body and
chassis.
[Tire rotation]
“Rotate” tires at the regular intervals in order to
equalize tire wear and thereby make full use of
each tire. Refer to below figure for the scheme
of rotation. Adherence to this scheme prolongs
tire life.

Wheel repairs that use welding, heating, or peen-
ing are not approved. All damaged wheels should
be replaced.
[Tire demounting and mounting]
Use a ‘tire changing machine to mount or de-
mount tires. Follow the equipment manufac-
ture’s instructions. Do not use hand tools or tire
irons alone to change tires as they may damage
the tire beads or wheel rim.
Rim bead seats should be cleaned with a wire
brush or coarse steel wool to remove lubricants,
old rubber and light rust. Before mounting or
demounting a tire, the bead area should be
well lubricated with an approved tire lubricant.
After mounting, inflate to 220kPa (32 psi) so
that beads are completely seated.
WARNING:
Do not stand over tire when inflating. Bead
may break when bead snaps over rim’s
safety hump and cause serious personal
injury.
Do not exceed 240kPa (35 psi) pressure
when inflating. If 220kPa (32 psi) pressure
will not seat beads, deflate, re-lubricate and
reinflate. Over inflation may cause the bead
to break and cause serious personal injury.1
Inflate to specified pressure.
[Tire repair]
There are many different materials and techni-
ques on the market to repair tires. As not all of
these work on all types of tires, tire manufactu-
rers have published detailed instructions on how
and when to repair tires. These instructions can
be obtained from the tire manufacturer.
