Chapter 5 Front Suspension SystemSection 1 Front Suspension SystemDescription on front suspension structureThis model uses strut swing arm independent suspension with stabilizer bar.
The shock absorber upper end is flexibly connected to the body through the shock absorber mounting seat, the
lower end is rigidly connected to the steering knuckle. The coil spring encloses the shock absorber (coil spring
geometrical axial line does not coincide with that of the shock absorber piston rod), and is supported between the
upper and lower spring seats.
Both ends of the stabilizer bar are connected to the shock absorber through the strut bar ball pin and the intermediate
part is supported on the lower front body by the rubber bushing and support frame.
The front cushion sleeves the shock absorber piston rod head to restrict the wheel jump limit position and plays
the role of buffer.
The thrust ball bearing, installed between the spring upper seat and the shock absorber mount, is used for the
relative rotation upon steering of the shock absorber rigidly connected to the steering knuckle to the shock absorber
mount flexibly connected to the body.
"L" type lower swing arm is secured to the lower engine compartment with the press plate through elastic rubber
bushing and hinge, and its outer end is connected to the steering knuckle through the ball stud pin which is attached
to the lower swing arm by 3 high intension bolts. The ball stud pin can be removed and replaced when it is worn.
The ball seat material is saturated polyester containing oil, featured in comparatively high intensity and wearability
and good self-lubrication performance. Proper amount of grease has been added during the assembly and there is
no need for additional filling during the normal operation.See the table for the front suspension technical parametersFront Suspension SystemFront Suspension System4-38Item

Section 3 Front Wheel AlignmentAdjustment:1. Check tire
2. Measure the vehicle height
Vehicle height:Tire sizeFront1 (mm)Rear2 (mm)
175 / 65R14 82H191 265
185 / 60R15 84H192 265Front Suspension System-Front Wheel Alignment4-43 1.front measure point
Measure the distance between the ground and the front underside
suspension mounting bolt center
2.rear measure point
Measure the distance between the ground and the rear axle beam mounting bolt center
Notice:
Before the wheel alignment,adjust the body to the specified height.If the body height is out of spec,adjustment
shall be done by pressing or raising vehicle body.
3. Check the Toe-in
Toe-in:
If the toe-in is out of spec, adjust the ends of rack.
4. Adjust the Toe-in
(1) Remove the clamp of the rack boot
(2) Loose the jam nut of tie rod
(3) Adjust the Toe-in by rotating the same turns of both ends of
rack.
Tips: Adjust the toe-in to the intermediate value of spec.
(4)Make sure the same length for both ends
The length difference of left and right: 1.5mm or smaller
(5)Tighten the jam nut of the tie rod
Torque: 47N.m
(6)Seat the boot and crimp the clamp
Tips: rack boot must not be twistedFront

Fully steer the wheel and measure the angle
The angle of wheel:
If the kingpin caster angle and the kingpin inclination be out of spec, check the damage and abrasion of
suspension parts after the correct adjustment of camber angle. If there is deviation with spec for right and left wheel angle, check the rack length of left and right ends.
6. Check the camber, caster and steering axle inclination angle
7. Adjust the camber angle
Notice:
Check the toe-in after adjust the camber angle
(1)Remove the front wheel
(2)Remove the two nuts under the shock absorber
If you need to reuse the bolts and nuts, apply the engine oil on
the nut thread
(3)Clear the mounting surface of the knuckle and shock absorber.Front
