(2) Remove front brake caliper assembly.
(3) Remove front brake disc.
(4) Check the bearing backlash.
Set a dial indicator near the front wheel hub center to check
the backlash.
Maximum: 0.05mm
If the backlash exceeds the maximum value, replace the front
wheel hub bearing.
(5) Check the front wheel hub deviation
Using a dial indicator, check the deviation of the surface of the
wheel hub outside the hub bolt.
Maximum: 0.07mm
If the backlash exceeds the maximum value, replace the front
wheel hub subassembly.Propeller Shaft/DriveshaftPropeller Shaft, Driveshaft and Transaxle4-17 -
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

Chapter 8 Power Steering SystemSection 1 Power Steering System3. Precaution: (1) Precaution for steering system
Make sure of the correct replacement of parts, incorrect replacement might affect the performance of the
steering system and lead to driving accidents.
(2) Precaution for SRS System
This vehicle is equipped with SRS (Supplemental Restraint System), driver side air bag and front passenger
side air bag.
Failure to carry out service operations in the correct sequence could cause the unexpected deployment of
the air bag during servicing, possibly leading to a serious accident.1. Power Steering System Description Power Steering System consists of the steering wheel, steering transmit device, power steering fixed device
and steering pipelines. The steering gear is rack and pinion type.2. Major parameters for steering system:Power Steering System-Power Steering System4-67Item
