Description
Vehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect the
handling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering,
good directional stability, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufacturer and type
of equipment used. The manufacturer’s instructions should always be followed to ensure accuracy of the alignment.
On this vehicle, the suspension angles that can be adjusted are as follows:
Front Axle
•Camber
• Caster
• Toe-in
Rear Axle
• Camber
• Toe-in
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curb
height specification. Curb height is the normal riding height of the vehicle. It is measured from a certain point on the
vehicle to the ground or a designated area while the vehicle is sitting on a flat, level surface.
Operation
Curb Height Measurement
The wheel alignment is to be checked and all alignment adjustments made with the vehicle at its required curb height
specification.
• Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack.
• The tires are to be inflated to the recommended pressure.
• All tires are to be the same size as standard equipment.
• Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
• Vehicle height is not adjustable.
• If the measurement is not within specifications, inspect the vehicle for bent or weak suspension components.
• Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for
a match.
• Once removed from the vehicle, compare the coil spring height to a new or known good coil spring. The
heights should vary if the suspect spring is weak.
NOTE :
Prior to reading the curb height measurement, the front and rear of the vehicle must be jounced to settle the sus-
pension. Induce jounce by pushing down on the center of the bumper (fascia), using care not to damage the vehicle,
moving the vehicle up and down, gradually increasing the suspension travel with each stroke. Release the bumper at
the bottom of each stroke, repeating this action several times. Perform this to both front and rear suspensions an
equal number of times.
Pre-Wheel Alignment Inspection
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary cor-
rections must be made to the vehicle to ensure proper alignment. 1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equip- ment.

10–39Chery Automobile Co., Ltd.

Downloaded from www.Manualslib.com manuals search engine 3. Check the tires on the vehicle. The tires are to beinflated to the recommended air pressure. All tires
must be the same size and in good condition with
approximately the same tread wear.
4. Check the front tire and wheel assemblies for excessive radial runout.
5. Inspect all suspension component fasteners for looseness and proper torque.
6. Inspect all ball joints and all steering linkage for looseness and any sign of wear or damage.
7. Inspect the rubber bushings on all the suspension components for signs of wear or deterioration. If any bushings show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.
8. Check vehicle curb height.
Wheel Alignment Setup
1. Position the vehicle on an alignment rack.
2. Install all required alignment equipment on the vehicle, per the alignment equipment manufacturer’s instructions. On this vehicle, a four-wheel alignment is recommended.
3. Read the vehicle’s current front and rear alignment settings. Compare the vehicle’s current alignment settings to the vehicle specifications for camber, caster and toe-in.
NOTE :
Prior to reading the vehicle’s alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rear
first, then front) by grasping the center of the bumper and jouncing each end of the vehicle an equal number of
times. The bumper should always be released when vehicle is at the bottom of the jounce cycle.

Inspect the following for damage:
•Inspect the tires.
• Inspect the rims.
Replace any tire or rim that is found to be damaged.
Tire Wear
Inspect the following for accurate tire wear:
• Check the depth of tire remaining tread.
• Standard tire: not less than 1.6 mm.
• Snow tire: 50% tire tread.

Downloaded from www.Manualslib.com manuals search engine DIAGNOSIS & TESTING
Vehicle Inspection
Visual inspection of the vehicle is recommended prior to road testing or performing any other procedure. Raise the
vehicle on a suitable hoist.
Inspect the following:
•Inspect tires and wheels for damage, mud packing and unusual wear; correct as necessary.
• Check and adjust tire pressure to the pressure listed on the label attached to the driver’s door opening.
Tire and Wheel Vibration
Tire and wheel imbalance, runout and force variation can cause vehicles to exhibit steering wheel vibration.
NOTE :
Balance equipment must be calibrated and maintained per equipment manufacturer’s specifications.
Tire Wear Patterns
Tire wear patterns can be traced to the following tire conditions:
•Under inflation will cause wear on the shoulders of tire.
• Over inflation will cause wear at the center of tire.
• Excessive camber causes the tire to run at an angle to the road. One side of tread is then worn more than the
other.
• Excessive toe-in or toe-out causes wear on the tread edges and a feathered effect across the tread.
NOTE :
Tread wear indicators are molded into the bottom of the tread grooves. When tread depth is 1.6 mm, the tread wear
indicators will appear as a band. Tire replacement is necessary when indicators appear in two or more grooves, or
if localized balding occurs.
Wheel Out-Of-Round Inspection
• Raise vehicle and securely support it.
• Attach a dial indicator on the edge of the rim and measure its unevenness.
• Replace the rim if necessary.10

tion, steering effort is significantly increased.
WARNING!
Power steering fluid, engine parts and exhaust system may be extremely hot if engine has been running. Do not
start engine with any loose or disconnected hoses. Do not allow hoses to touch hot exhaust manifold or cata-
lyst. Fluid level should be checked with the engine off to prevent personal injury from moving parts.
