GENERAL INFORMATION
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.
