Prechecks

TEST CONDITIONS
Wheel alignment should be checked only after the following conditions have been met:
^ All excessive mud, dirt, and road deposit accumulation have been removed from chassis and underbody.
^ Inspection has ruled out the possibility of worn or damaged suspension components which need to be replaced.
^ Spare tire, wheel, jack, and jack handle are in position.
^ Front seats are in rear-most position.
^ Tire condition and inflation (cold) have been verified to be uniform and correct.
^ Wheel bearing preload has been checked, and adjusted if necessary.
^ Check the curb load conditions.

DESCRIPTION
The MacPherson strut suspension system is integrated into the vehicle structure at all four wheels. This minimizes the number of points that can be, or need to be, adjusted. Front toe is adjustable, and two available settings make limited camber adjustment possible. Caster is established by front suspension mounting points and can be adjusted only by replacing worn or damaged components.

BEFORE THE ALIGNMENT
^ Before measuring and setting the front-wheel alignment, rest the front tires on turn plates.
^ Before setting any alignment angle, bounce the vehicle three times at each end. This establishes the actual standing curb height (trim height).
^ Always perform a wheel alignment on a level alignment rack.
^ Check all the factors of the front-wheel alignment except turning angle before making any adjustments.
^ Check the turning angle only after the camber and toe have been adjusted to specification.
^ Rear toe checked.

AFTER THE ALIGNMENT
^ Always road test a vehicle after an alignment. If the vehicle still pulls, never condemn the alignment until first switching the front tires. This will usually cure any pull problem. Tire Lead
^ If the vehicle still pulls in the same direction, double check the alignment and rear tracking. If the vehicle pulls in the opposite direction, rotate the tires and road test the vehicle again.
