1987 SUZUKI GRAND VITARA tires

5. Fig. O-7 and O-8 show how to lift the car by
using a hoist.
WARNING:
l When using frame contact hoist, apply
hoist as shown below (right and left at
the same position), Lift up the car till 4
tires are a little off the ground and make
sure that the car will not fall off by try-
ing to move car body in both ways. Work
can be started only after this confirma-
tion.
l Before applying hoist to underbody,
always take car balance throughout serv-
ice into consideration. Car balance on
hoist may change depending of what
part to be removed.
lFor suspention parts removal, follow pre-
vious steps 3 and 4.
l Make absolutely sure to lock hoist after
car is hoisted up.
When using frame contact hoist:
6. Orderliness is a key to successful overhauling.
Trays, pans and shelves are needed to set
aside disassembled parts in groups or sets
in order to avoid confusion and misplace-
ment. This is particularly important for
engine overhauling.
7. Have on hand liquid packing-SUZUKI
BOND No. 1215 (99000-31110) - for
ready use. This packing dope is an essential
item to assure leak-free (water and oil) work-
manship.
8. Each bolt must be put back to where it was
taken from or for which it is intended. Do
not depend on your hunch in tightening
bolts for which tightening torque values are
specified: be sure to use torque wrenches on
those bolts.
9. It is advisable to discard and scrap gaskets
and “0” rings removed in disassembly. Use
new ones in reassembly, and try not to
econimize gaskets and “0” rings.
10. Use of genuine SUZUKI parts is imperative.
Use of imitation parts is a big gamble on
safetyand performance. Use genuine
SUZUKI parts and live up to the trust your
customer places on you.
11. Special tools save time and ensure good
workmanship: They are available from
SUZUKI. Use them where their use is
specified. Moreover, your own safety is
assured by the use of special tools in many
of the disassembly and reassembly steps.

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.
@ Toe-in gauge
Fig. 18-36
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.

Steering Gear Box
Check steering gear box for evidence of oil
leakage. If leakage is found, repair or replace
and then refill specified oil to specified level.
Refer to“18-5 INSPECTION OF COMPO-
NENT” in this section for steering gear box oil.

Tires[Tire wear indicator]
When replacement is necessary, the original
equipment type tire should be used. Refer to
Tire Placard.
Check wear indicator, and replace tire when its
wear is the same level as the indicator.
Replacement tires should be of the same size,
load range and construction as those originally
on the car. Use of any other size or type tire
may affect ride, handling, speedometer/odometer
calibration, vehicle ground clearance and tire or
snow chain clearance to body and chassis.
NOTE:
NOTE:
Do not mix different types of tires on the same
car such as radial, bias and bias-belted tires
except in emergencies, because car handling may
be seriously affected and may result in loss of
control.
The mud & snow tire has a platform ttr indicate
wear in addition to tire tread wear indicator.
It shows up when 50% of tire tread is worn out.
When driving on muddy or snowy roads, check
if its wear is the same level as the platform and
if it does, replace the tire.
It is recommended that new tires be installed in
pairs on the same axle. If necessary to replace
only one tire, it should be paired with the tire
having the most tread, to equalize braking
traction.
[Inspection]
l Check tires for uneven or excessive wear, or
damage. If defective, replace.
l Check inflating pressure of each tire and,
as necessary, adjust pressure to specification.
l Check wheels for dent, crack or other damage.
l Check wheel nuts for tightness.
