Exam 120: Alignment Diagnosis and Service

Vehicle curb height should be checked and corrected before performing a wheel alignment.

What is the most common cause of memory steer?

Use the following information to answer the question: - The vehicle above will ________.

Cross camber and cross caster should be within 1/2 degree from one side to the other.

Strut rods, if they are adjustable, can be used to adjust which angle?

Technician A says to inflate the tires to manufacturer's specifications before performing a wheel alignment. Technician B says to thoroughly inspect the steering and suspension components before performing a wheel alignment. Which technician is correct?

The proper order in which to perform a four-wheel alignment is ________.

Which component is typically used to set rear camber in many vehicles?

Technician A says that, as wear occurs, camber usually becomes negative. Technician B says that, as steering linkage wear occurs, toe usually becomes toe-out from an original toe-in specification. Which technician is correct?

Which alignment angle is most likely to need correction?

Technician A says that TOOT is the last adjustment made in a four wheel alignment. Technician B says that TOOT is a diagnostic angle that is not adjusted in a typical alignment. Which technician is correct?

What is the maximum allowable steering wheel angle variation from straight?

Which angle is largest?

Technician A says that alignment sensor calibration is needed to compensate for bent wheels. Technician B says that sensor calibration is needed to compensate for uneven installation of the sensor on the wheel. Which technician is correct?

Technician A says that a vehicle must have new tires in order to perform a proper alignment. Technician B says that the tires should be the same size with the same treadwear in order to perform a proper alignment. Which technician is correct?

Technician A says that torque steer is normal on some FWD cars, especially during heavy acceleration. Technician B says that broken engine mounts can cause abnormal torque steer. Which technician is correct?

Technician A says that the alignment sensor heads only need to be compensated once per day. Technician B says that the alignment sensor heads should be compensated every time they are mounted on a wheel. Which technician is correct?

If the tie rod ends become worn, which angle is most affected?

Technician A says that a vehicle will pull (or lead) to the side with the most camber (or least negative camber). Technician B says that a vehicle will pull (or lead) to the side with the most positive caster. Which technician is correct?

Which angle is calculated as the wheels are turned from side to side?
