Exam 49: Wheel Alignment

____________________ is the distance comparison between the leading edge and trailing edge of the front tires.

The difference of rear toe from the geometric centerline is called the _____ angle.

Adjustments to front wheel camber or caster settings affect the turning radius angles.

An incorrect turning radius angle is being discussed. Technician A says replacement shims can be used in many vehicles to correct the condition. Technician B says steering or suspension parts are damaged. Who is correct?

____________________ is the angle between true vertical and a line drawn between the steering pivots as viewed from the front of the vehicle.

Technician A says tilting the top of the wheel forward will result in a negative caster. Technician B says tilting the top of a wheel outward will result in negative camber. Who is correct?

____________________ is the angle of the steering axis of a wheel from the vertical, as viewed from the side of the vehicle.

Technician A says if caster at both wheels is not equal, the vehicle will tend to drift toward the side with the most positive caster. Technician B says if camber is not the same on both wheels, the vehicle will pull toward the side with the most positive camber. Who is correct?

What is the correct sequence for adjusting alignment angles during a four-wheel alignment?

When performing an alignment the steering angle sensor may require calibration.

Aftermarket kits are only used to adjust rear camber and rear toe.

Technician A says the presence of an excessive thrust angle can cause poor directional stability on ice, snow, or wet pavement. Technician B says an excessive thrust angle can increase tire wear. Who is correct?

When does steering angle sensor calibration need to be performed?

Which of the following tire wear patterns will result from excessive negative camber?

Front-wheel-drive vehicles with strut suspensions typically have a higher SAI angle than rear-wheel-drive vehicles with short-long arm suspension.

Technician A says comparing the SAI, included, and camber angles can help identify damaged or worn components. Technician B says if the toe-out-on-turns [turning angle] is not correct, the tie-rods, steering arm, or steering knuckle are damaged and will need to be replaced. Who is correct?

The ____________________ bolt and cam assembly is often used to adjust camber and caster settings.

Proper alignment is possible if the vehicle ride height is incorrect.

______________________ may also be called turning radius or turning angle.

Unequal SAI angles may cause ______.
