FRONT SUSPENSION AND STEERING TROUBLE DIAGNOSIS
Before making any adjustment to a vehicle because of suspension, steering and
tire wear problems, it is necessary to make a preliminary inspection of all moving
parts from the steering wheel to the road wheels.
Wear, looseness or binding of any of the moving parts of the steering system and
suspension system will affect vehicle alignment . Vehicle misalignment cannot be
corrected as long as conditions of bind or looseness exist .
A complete inspection
should be made, even if the cause of the problem is suspected .
