Exam 49: Wheel Alignment

During a four-wheel alignment, front toe is set to the vehicle's centerline.

The outside edge of the right front tire is worn, but the center and inside edge are almost new. The wear on the outside surface is smooth and not scalloped, feathered, or sawtoothed. The left-side tire shows no sign of wear. What could be the problem?

All the following angles are adjustable during wheel alignment EXCEPT:

Technician A says caster is the first angle checked during a two wheel alignment. Technician B says all vehicles with strut suspension have caster adjustments. Who is correct?

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

What is scrub radius?

A four-wheel alignment is sometimes called a(n) ____________________-wheel alignment.

In what direction must the top of a tire and wheel assembly be moved to add more positive camber?

SAI [steering axis inclination] helps the vehicle's steering system return to straight ahead after a turn.

Front wheel drive vehicles with strut suspension typically have no provision for adjusting caster.

Before adjusting toe on a rack-and-pinion system, Technician A loosens the small outer bellows clamp. Technician B installs a steering wheel holder between the steering wheel and the driver's seat. Who is correct?

Technician A says thrust line deviations are usually caused by the shifting of the rear axle on its spring supports. Technician B says rear wheel misalignment or damage from an accident can cause thrust line deviations. Who is correct?

When the right front wheel is turned 20 degrees to the left the left front wheel moves only 18 degrees. What could be the problem?

____ is the angle represented by the tilt of a wheel inward or outward from the vertical as viewed from the front of the car.

Which of the following statements is NOT correct?

Technician A says a vehicle may wander as a result of excessive negative caster. Technician B says positive caster will result from excessive toe-in. Who is correct?

Which of the following statements is NOT correct?

Unequal caster angles cause the vehicle to steer toward the side with greater caster.

Define positive camber.

SAI + camber = ______
