3、Check front-wheel bearing clearance, and replace front-wheel bearing if necessary.

4、Check if rims and tyres wobble.

5、Check if ball joint of cross connecting rod loosens.

6、Park the vehicle without luggage and persons on the level ground.

7、Heights from left and right sides of fender apron to vehicle center line can’t exceed standard height of checking

suspension.

8、Wobble wheels to check if shock absorber functions properly.

Note：*1 Make sure fuel tank is full of fuel, radiator coolant and engine oil are in the given height, the tyre jack and basic

hand tools are in the specified position.

Rims and Tyres

1、

Sight Check

Check the rim and tyre, it is needed to replace

them, if crack and damage and deformation of

the rim and tyre are found .(see the figure)

Figure : Tyre Abrasion

2、

Tyre Abrasion

(1)

Check tread depth left. Standard

tyre illustrated in the figure: at least 1.6mm

Snow tyre: 50% of tread.

（

It is needed to replace the tyre, if abrasion indicating

strip unfolds.

Abrasion of Tyres

Undue abrasion of tyres illustrated in the

right figure may occur, consult possible

reasons and disposal methods in following

table. (See the figure)

Toe-in Wear

Figure: Tyre Abrasion

Single-side Wear

Possible reasons

Disposal methods

（

a）

*Lack of tyre pressure (abrasion on

both sides)

*Turn in high-speed

*Location of tyres hasn’t been adjusted.

* Measure and adjust tyre pressure

*Speed down

*Adjust tyre location

（

b）

* Tyre pressure is too high.

*Location of tyres hasn’t been adjusted.

*Measure and adjust tyre pressure

*Adjust tyre location

（

c）

* Incorrectness of toe-in

*Adjust toe-in

（

d）

*Incorrectness of camber or caster

* Suspension system failure.

*Tyre imbalance

*Out-of-round of brake drum or the

disk.

* Other mechanical problems

*Location of tyres hasn’t been adjusted.

*Adjust ,fix or replace the axle and

suspension system.

*Fix or replace

*Keep the tyre in dynamic balance or

replace it.

*Calibrate or replace

*Calibrate or replace

*Adjust tyre location

Precautions related to rims and tyres

（

1）Don’t use substandard rims and tyres.

（

2）Aluminum alloy steel rim is likely to be scraped, so use soft fabric to clean it instead of steel brush. Don’t use

boiling water to clean it directly if cleaning vehicles with steam.

（

3）If

toothed compound

, such as mud or slurry is attached to aluminum alloy steel rim, it is needed to clean it with

neutral cleanser as quickly as possible to avoid damaging.

5、Replacement of tyres

（

1）Before equipping inner tube valve, check if valve

hole is smooth without a bur. Then apply glycerol onto

the rubber surface of inner tube valve or dip inner tube

valve into glycerol.

It is finished with installation

correctly via passing binding ring of

inner tube

valve through the hole of the vehicle under the pressure

of 200-400N

with special tools (Suds is allowable

for replacement of

glycerol.

)

（

2）Before equipping tyres, apply glycerol or suds

onto the bead and note: when there’s a dub mark on

wheel rim, align the mark of tyre uniformity test with the

dub mark. When there isn’t a dub mark on wheel rim,

align the mark of dynamic balance test with inner tube

valve. When there is neither a dub mark on wheel rim nor

the mark of dynamic balance test, but there is a mark of

static balance test, align test mark of static balance with

inner tube valve.

6、Tyre pressure

Check pressure of all tyres, including spare tyres and adjust

it when needed. Inflate tyres according to given pressure

strictly. Air pressure can’t exceed 10% of rated air pressure

during inflation. When installing spare tyres assy separately,

rated inflation pressure shall be 3.5bar and they shall be

stocked in isolation from four wheels for equipping the

vehicle. Before processing four-wheel alignment, check

tyres pressure of 4 wheels and adjust it : front wheel :

2.2bar，rear wheel 2.0bar.(See the figure)

Check tyre pressure

Air Leakage

7、Air Leakage

Make sure there’s no air leakage of inner tube valve as

shown.

8、Check out-of-flat of rims

（

1）Prop up vehicles high and safely.

（

2）Fix up micrometer indicator equipped with

cylindrical finger（Φ10）on the edge of wheel

Check out-of-flat of rims

rim to measure depth of out-of-flat.(see the figure)

(3)If needed, replace the

rim.

Note: allowable deformation in wheel rim:

allowable maximum value of out-of-flat depth average on both edges of wheel rims can’t exceed:

steel wheel rim:5mm ,

aluminum alloy wheel rim:3mm

9、Adjust tyre location

In view of extending tyre life and making sure tyre abrasion situation, adjust tyre location per 6000km

（

3750miles）.

(See the figure)

Caution:

*It is needed to use the highest quality tyre for front wheel.

*After adjusting tyre location, adjust tyre pressure to assigned

pressure value.

Adjust tyre location

10、 Wheel balance adjustment

After tyre inflation, screw valve protecting cap

to process dynamic balance test and equip

suitable balance weight on the inner and outer

edges of wheel rim according to the requirement,

and require the last unbalance degree assy

is less than 100g· cm (about 5g of balance weight

on the inner and outer edges of wheel rim)
