Steering knuckle assembly removal
1. Preparation
First, remove the front wheel, the front shock absorber with
coil spring assembly, and the steering knuckle coupling
bolt in turn. For detailed steps, please refer to the removal
of the wheel and the front shock absorber with coil spring
assembly.
2. Remove propeller shaft nuts
(a) First, pry the flattened areas of the propeller shaft's nuts
into a circle with a chisel.
(b) Half-insert a long bolt or metal bar into the brake disc
holes to loosen the nuts (shown on the left).
Tightening torque: 225±20 N·m

attention to personal protection.
4. Remove the cotter pins and lock nuts of the steering tie
rod and the lower swing arm
Because the ball stud and steering knuckle act in conjunction
with the tapered bore, they can not yet be removed after re-
moving the nuts. Pound the steering knuckle arm (unfinished
surface) with a hammer. Positions are shown on the left.
Shake to loosen.
Caution:
1. To avoid separating the ball studs, do not pound the
tie rod and the lower swing arm with a hammer.
2. To avoid damaging the thread, do not hammer the
ball stud's head.

Wheel and Tire
Tire
Remark
This vehicle's tire is of the tubeless type. The optimal design condition is met when the inflation pressure is at
the recommended value, and the tire is under full load. Maintaining suitable tire pressure and proper driving
habits greatly influence the tire's use life. For the vehicle, it improves riding comfort, stability, and handling. For
the tire, it reduces tread wear, damage to the tire and extends tire life. Overloading, speeding, and unnecessary
emergency braking will all add to the tire's wear and tear.
Tire pressure measurements should be taken under normal temperature. If the tire pressure rises due to motion
generated heat when driving, cooling it will return to the normal temperature. Therefore, do not deflate the tire
when the air pressure has risen to this point. The tire's air pressure will naturally and slowly decrease when used
under normal conditions. Hence please inspect the air pressure regularly (suggested once a month). The spare
tire should be kept in a useable condition at all times.
Inspect the tire pressure when it is cool monthly or before a long drive. Adjust the tire pressure to the recom-
mended level. The air pressure will normally rise because the tire warms up due to movement. Therefore, after
driving, you absolutely must not deflate or reduce the tire's air pressure, as deflating could reduce the cool tire's
air pressure.
Tire inflation
During a new tire's initial stage of use, warning due to bending motions will cause the tire to swell, and thus
reduce the corresponding air pressure. After 24 hours or 2000-3000 km worth of drive, charge the air pressure.
After inflating, check if the air nozzle core is leaking air with soapy \
water, then lock on the cap.
Possible problems caused by tire pressure
Exceeding the recommended air
pressure
Below the recommended air pressureSame vehicle axle, different
air pressure
Possible problems it
can create
1. Bumpy ride
2. The tear or rupturing of the tire
3. Rapid wear of the tire tread's center
1. Noisy turns
2. Uneasy turns
3. Tread edge wear is accelerated and uneven
4. The tire's rim is damaged or ruptured
5. The tire cord ruptures
6. High tire temperature
7. Steering failure
8. Large oil consumption
1. Uneven braking
2. Over steering
3. Steering failure
4. Deviation while accelerating
Tire and wheel (steel wheel) installation instructions
When installing the tire and wheel, the tire's radial hardware components, also called "high spot", should be at
the same level of the wheel's minimum radius or so called "low spot".
The "high spot" of the tire is initially marked by the paint spot on the side of the tire's surface. This paint will
eventually be washed away.
The "low spot" of the wheel is initially marked by a paint spot on the wheel flange. Whenever the tire is
removed from the wheel, the tire and wheel need re-balancing to make sure the vehicle runs smoothly. If no
paint spot is found on the tire, draw a line on the tire and the wheel before they are removed, in order to make
sure that the tire and the wheel will be re-assembled at the same place.\

Tire replacement
When a tire needs to be replaced, make sure to use a tire with the same specification as the original one. A new
tire used for replacement must be of the same dimension, load area, and structure as the original one. Using tires
that are different in dimension or type will influence the vehicle's riding comfort, handling, speedometer and
odometer calibration, vehicle ground clearance, and the clearance between the tire or the tire's snow chain and
the vehicle body or chassis.
It is suggested to use a new pair of tires on the same axle. If only one tire is needed to be replaced, make sure to
use a tire with a tread most similar to the original, so as to keep brak\
e power and traction balanced.
Warning: Do not mix radial tires, bias tires, bias belted tires, etc., which are of different structure on the
same vehicle unless it is an emergency. Mixing different tires would seriously influence the vehicle's
handling and stability, and even possibly lead to losing control of the vehicle.

Vehicle road test methods
1. Drive the vehicle and find out if the swaying is coming from the front tires or the back tires. Then replace the
identified problem tire with a good tire (one that has been tested on t\
he same model of vehicle).
2. If unable to determine the problem tire, replace the rear wheels. Continue with the road test. If the driving
condition obviously changes, replace the original tires, and only switch one at a time until the problem tire is
identified.
3. If no obvious improvement, replace all four tires with good tires, and then replace the original tires one by
one following the steps mentioned above.
Tire's abnormal wear and tear
Tire's abnormal wear and tear includes uneven and excessive
w e a r o f t h e t i r e . T h e r e a r e m a n y c a u s e s f o r t h i s . F o r
example, improper tire pressure, tire rotation has not been
timely maintained, bad driving habits, abnormal front wheel
location, etc.
Change the tires when the below situations happen:
1. When the extents of wear and tear of the front and rear
tires are different.
2. When any of the tire's tread has uneven wear and tear.
3. When the extents of the wear and tear of the left and right
front tires are different.
4. When the extents of wear and tear of the left and right rear
wheels are different.
5. When the groove of the tire tread wear appears abnormal
and the tire's contact area starts to flatten.
Inspect the front wheel alignment when the following
situations occur:
1. When the extents of the wear and tear of the left and right
front tires are different.
2. When any of the tire's tread has uneven wear and tear.
3. When the tread pattern strip or pattern block of a front
tire's single side is badly worn.
[A]
[B]
[A]: Steering problems, air pressure not sufficient, or tire rotation has not been timely maintained. [B]: Abnormal front wheel alignment, tire or wheel structure is not the same.
Radial tire sway
Here the sway means the vehicle's front or rear part shakes
from side to side, together or individually. Tire sway is
caused by the steel wire belt inside the tire not being straight.
The sway is the most obvious when the vehicle runs at the
speed of 8-48 km/h.
Road tests can help finding malfunctioning tires. If the
malfunction is with the rear tires, then left and right shaking
or "swaying" would take place at the back of the vehicle.
Here the driver of the vehicle would feel as if someone were
pushing from one side of the vehicle.
If the malfunction is with the front tires, swaying would be
even more obvious. The metal plate in the front may seem
moving back and forth, and the driver feels as if he/she were
at the vehicle's center of rotation.
Wear marks
There are several tread wear marks (refer to location A in the
diagram shown on the left) inside of the tire's pattern groove.
These marks indicate that the tire has been worn to the point
of replacing.
Before the tire's usage limit, indicated by the remaining
pattern's depth, reaches 1.6 mm (and its main pattern groove
bottom protrudes to the same level), for your safety, please
replace the tire.
When serious eccentric wear leads to the partial protrusion
of the cord fabric level, or outside objects damage the tire to
a depth that reaches the cord fabric level or steel band level,
stop using the tire.
