DIAGNOSIS
GENERAL DIAGNOSIS
Problems in the steering, the suspension, the tires,
and the wheels involve several systems. Consider all
systems when diagnosing a complaint. Some problems,
such as abnormal or excessive tire wear and scuffed
tires, may be the result of hard driving. Always roadtest the vehicle first. If possible, do this road test with
the customer.
Proceed with the following preliminary checks. Correct
any substandard conditions.
Preliminary Checks
