Chery Tiggo. Manual — part 342
Operation
The steering column is the mechanical linkage between the steering wheel and the steering gear. The steering col-
umn shaft then connects the steering column to the steering gear. The tilt function of the steering column is con-
trolled by a mechanical lever on the underside of the steering column, which uses a cam to lock and unlock the
steering column.

GENERAL INFORMATION
DIAGNOSIS & TESTING
Vehicle Inspection
There is some noise in all power steering systems. One of the most common is a hissing sound. Hiss is a high
frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high
velocity steering fluid passing through an orifice. There is no relationship between this noise and steering perfor-
mance. The hissing sound is commonly heard during the following operations:
• Evident at a standstill
• At park with the engine running
• When the steering wheel is at the end of its travel

Removal & Installation
WARNING!
Before servicing the steering column, the airbag system must be disarmed. Failure to do so may result in acci-
dental deployment of the airbag and possible personal injury (See Airbag System Disarming Procedure in Sec-
tion 14 Restraints).
NOTE :
To help maintain alignment of the spiral cable connector during reassembly, apply a small piece of tape to the spiral
cable and the steering column to keep them in alignment.
1. Set the front wheels to the straight-ahead position.
2. Disconnect the negative battery cable.
3. Remove the driver airbag (See Driver Airbag Removal & Installation in Section 14 Restraints).
4. Disconnect the spiral cable electrical connector.
5. Remove the steering wheel lock nut (1).
(Tighten: Steering wheel lock nut to 25 - 30 N·m)
6. Using the steering wheel puller, remove the steer-
ing wheel.
7. Installation is in the reverse order of removal.
Installation Notes:
• The spiral cable could be damaged if installed in an improper position.
• Do not rotate the spiral cable quickly or beyond the limit of turns (this can cause the cable to snap).
• Verify the airbag system is operating properly after the repair is complete.

Inspection - Steering System
Steering Wheel Free-Play Inspection
• Set the front wheels to the straight-ahead position with the engine idling (hydraulic system is working).
• Slightly turn steering wheel to the right and left, and before the wheels begin turning, measure the free play of
steering wheel.
− Maximum limit: 40 mm.
• If the free play exceeds the limit value, inspect the gap between the steering shaft joint and the steering link-
age. Repair or replace the related parts as necessary. If the free play still exceeds the limit value, turn the
steering wheel to the right position with the engine off. Apply 5 N·m of load to the steering wheel and inspect
the free-play again.
− Standard value: Less than 15 mm (steering wheel free play with the engine off)
• If free play exceeds standard value, remove steering gear housing and inspect the gross torque of pinion gear.
Static Steering Force Inspection
• Park the vehicle on a level surface, and turn the steering wheel to the straight-ahead position. Start the engine,
adjust engine speed to 1000 ± 100 RPM.
CAUTION:
After adjusting the engine speed, return it back to standard idle speed.
• Connect a spring scale to the outer circle of steering wheel. Measure the steering force required when turning
the steering wheel leftward and rightward (within 1.5 circles) at the straight-ahead position. If obvious steering
force fluctuation exists, inspect the steering force as necessary.
− Standard steering force: Less than 34 N·m
− Fluctuation tolerance: Less than 5.9 N·m
• If the measured force exceeds the standard value, see the trouble shooting section for inspection and adjust-
ment.
