4.2 Removal of rear axle assembly

4.2.1Remove the four connecting bolts of rear axle

and brake assembly via 13# sleeve.

Torque: 70±5N.m

4.2.2 Remove the hinged bolts connecting rear axle and

vehicle body via 17# sleeve. Then remove the rear axle.

Torque: 110±10N.m

5. Assembly procedures

The assembly procedure is reverse to that of disassembly.

Ⅲ. Adjustment of four-wheel alignment

Please use four-wheel alignment gauge as recommended by

Chery Company to carry out parameters detection and

adjustment.

1. Adjustment of front wheel toe-in

Optic test instrument or mechanical toe-in regulator can be

used for toe-in adjustment.

1.1 In accordance with requirements for test instrument, make

adjustment preparations for wheel alignment.

1.2 Loosen the lock nut fastening rightward connecting tie rod

and elastic ring, turn the toe-in regulation rod to adjust length

as required to get prescribed value.

Toe-in value: 10′±6′

1.3 Fasten the lock nut, remount circlip of the jacket, and

check whether the lock nut is tightened, and ensure the jacket

is in right position;

Torque: 55±5N.m

1.4 After adjusting toe-in of front wheel, check whether the

steering wheel is horizontal. Otherwise, loosen the lock nut of

steering wheel, adjust steering wheel to horizontal position,

and tighten up the lock nut of steering wheel to the torque

value as required.

2. Adjustment of front-wheel camber angle

2.1 Under normal condition, it is unnecessary to adjust

camber angle after assembling independent suspension

and wheel steering knuckle, if found camber angle

exceeds tolerance range due to other reasons, the

connecting bolt of independent suspension and steering

knuckle can be used for adjustment. Front-wheel camber

angle: - 30′±60′.

2.2 Prior to adjustment, check (visual inspection) the

parts of running system, and replace worn parts accordingly.

2.3 If found front-wheel camber angle exceeding tolerance,

loosen the connecting bolt fastening shock absorber and

steering knuckle, and move the wheel for rectification.

3. Adjustment of kingpin caster angle

Kingpin caster angle guaranteed by designed structure, it is

unnecessary to adjust in service. Kingpin caster angle:

3.13°±1°, if parameters exceed prescribed limit, only replace

steering knuckle.

4. Adjustment of rear wheel positional parameters

All of the rear wheel positional parameters shall be

guaranteed through design process.

4.1 Rear wheel camber angle: 30′±30′.

4.2 Rear wheel toe-in: 15′±15′.

4.3 If rear wheel positional parameters are changed and

exceed prescribed limit due to rear axle deformation resulted

from tremendous impact force, it can only be remedied via

rectifying or replacing rear axle.

Ⅳ.Installation of tire and regulation of air pressure

1. Fit tire valve

Prior to installing tire valve, firstly check the valve port to ensure whether it is smooth and free
from burr, and then apply glycerol on the rubber body surface, will soak the tire valve into glycerol.
Pull or press (200 - 400N) using special tools to make the locating ring of the valve can go through
the wheel holes, to this point, the assembly is completed (soap water is allowed to substitute
glycerol).

2. Fit the tire

Before fit the tire, apply glycerol or soap water along the cycle of tire bead, meanwhile, note that:
2.1 When there is colored dot on the wheel rim, align the uniformity testing mark of tire to the
colored dot mark of wheel rim.
2.2 When without colored dot on the wheel rim, align the dynamic balance testing mark of tire to
valve position.
2.3 When without colored dot on the wheel rim, additionally, there is no dynamic balance testing
mark, however, static balance testing mark is available, at this point, align the tire valve to the static
balance testing mark.
2.4 The description concerning the uniformity, dynamic balance and static balance testing marks
for tires will be additionally provided in writing by the product division of Chery Company or
suppliers. In addition, this kind of descriptions will clearly be indicated on process sheet.
2.5 Carry out tire inflation strictly in accordance with specified pressure. During inflating process,
air pressure shall not exceed 10% of rated pressure. When performing separate packaging to spare
wheel assembly, the rated inflation pressure shall be 3.5bar, and the spare wheel assembly shall be
stored separately from four wheels. Prior to carrying out four-wheel alignment, check four-wheel
tire pressure and adjust air pressure. Front wheel pressure shall be 2.0±0.2 bar; the rear wheel shall
be 2.2± 0.2bar.

3. Tire inflation

After completion of tire inflation, screw up the protective cap of valve, and then carry out dynamic
balancing test. Fit appropriate balance weight at the internal and external fringe of wheel rim as
required. It is required that the unbalancedness of the final assembly shall be less than 100g·cm,
which is approximately equivalent to a 5g balance weight at the internal and external fringe of
wheel rim.
Note: each wheel and each side can use only one balance weight. Additionally, its maximum mass
shall not be more than 70g. During assembling process, never hit the balance weight too heavy.
Otherwise, replace balance weight in time. In addition, never use the replaced balance weight
again.

4. Installation of wheel and tire assembly

When fixing wheel and tire assembly, first, manually screw up the wheel bolt onto the hub for
pretension, after that use special tools for tightening in accordance with diagonal process.
Tightening torque shall be 110±10N.m. It is prohibited to use impact wrench to prevent from wheel
damage, over loose or over tight. It is not allowed to apply grease on wheel bolt (For newly
assembled wheel and tire assembly, after initial 100km traveling, it is required to tighten the wheel
bolts once to guarantee appropriate tightening torque, and the inspection of wheel bolt tightening
torque is one of the routine maintenances).

5. Tightening method of wheel nut

Tighten the fixing nut in a decussate way, the tightening force shall be approximately equal, then
wheel shall be able to turn freely. When carry out final tightening, the wheel shall be on the ground.

6. Assembly of trim cover

Mount trim cover or place trim cover as required. When fitting clip- type trim cover, place knock
in position by hand or via rubber tools.
