Exam 49: Wheel Alignment

What is setback, and what can cause it to occur?

What is the difference between a two wheel alignment and a four wheel alignment?

The ideal situation is to have all four wheels at zero running toe when the car is traveling down the road.

Four-wheel alignment concepts are being discussed. Technician A says the wheels are adjusted to be parallel to one another. Technician B says the wheels are adjusted to be perpendicular to a common centerline. Who is correct?

On some models a pop rivet must be removed from the strut mount before a camber adjustment can be made.

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 incorrect, the tie-rods, steering arm, or steering knuckle will be damaged and need to be replaced. Who is correc t?

Which of the following statements is false?

Toe-out-on-turns may also be called turning ______________________ or turning ______________________ .

Describe the difference between a two-wheel alignment and a four-wheel alignment.

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?

Identify six prealignment checks that should be made before performing a wheel alignment.

After a two wheel alignment, the steering wheel on the vehicle is not centered. Technician A recommends a four wheel alignment to determine whether the rear wheels are parallel to one another and perpendicular to a common centerline. Technician B says if the steering wheel is not centered after an alignment, it should be pulled off the column and correctly positioned. Who is correct?

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

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

Incorrect caster angles cause tire wear problems.

____________________ is the last alignment angle to be set.

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

SAI + camber = ______

The outside edge of the right front tire is worn, but the center and inside edges 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?

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