Deck 68: Wheel Alignment Service

Question 1

3)Camber wear results as springs on an aging vehicle sag, changing the height of suspension components.

Answer 1

True

Question 2

17)Some ____________________ have a gauge that measures in degrees how far a wheel is turned to the right or left.

Answer 2

radius plates

Question 3

1)A vehicle with worn or loose parts should be aligned.

Answer 3

False

Question 4

20)The direction in which the rear wheels point is called the ____________________.

Question 5

16)____________________ is when a vehicle turns abruptly to the side during initial acceleration. This usually happens on front-wheel-drive (FWD) vehicles with axles of unequal lengths.

Question 6

4)Torque steer happens when a wheel with tie-rods at unequal heights goes over a bump.

Question 7

7)All of the following statements are true EXCEPT:

A) on the rear of a vehicle, toe equalizes between the two tires like it does on the front.
B) on radial tires on RWD vehicles with toe-in, the right front tire tends to toe in more than the left; its outside edge wears because the tire is rolling under at that edge.
C) radial tires on RWD vehicles with toe-in will both roll under, resulting in wear that looks like positive camber.
D) with toe-out, the inside edge of the left tire will roll under, resulting in wear on the inside edge of the left front tire.

Question 8

2)Incorrect alignment settings can result in pull, instability, and tire wear.

Question 9

15)The term MOST-Likely used to describe wheels that are closer together on one side of the vehicle than the other is:

A) toe change
B) wheelbase difference
C) thrust angle
D) setback

Question 10

8)Which of the following statements is LEAST-Likely true?

A) If tires are to be replaced, the new tires should be installed before attempting an alignment.
B) When correcting for road crown, camber creates less of a pull than caster.
C) Caster causes the camber angle of the wheel to change during a turn.
D) Roads are crowned (higher at the center than the outside) so that rain will run off.

Question 11

18)____________________ is the angle between the two front tires.

Question 12

12)Caster ____ between the front wheels should not be more than 1/2 degree.

A) steer
B) angle
C) spread
D) change

Question 13

11)All of the following statements are true EXCEPT:

A) when a rack-and-pinion steering gear is mounted out of level position, its tie-rods will be at equal angles.
B) aftermarket suspension parts sometimes relocate steering linkage connections, which can cause extreme toe change when the suspension moves.
C) the toe setting on a tire can change when the wheel goes into a pothole or over a bump.
D) turning radius is not an adjustable angle, but if a steering arm becomes bent, the turning radius is affected and the tires can squeal on turns.

Question 14

6)Which of the following is LEAST-Likely the cause of unusual tire wear?

A) Worn parts
B) Incorrect inflation
C) Steer pull
D) Incorrect wheel alignment

Question 15

10)While having a discussion, Technician A says that the manufacturers' specifications for maximum allowable steering wheel angle variation are typically + or - 6 degrees. Technician B says that it is normally + or - 8 degrees. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 16

9)While having a discussion, Technician A says that in most vehicles, it is important that the steering wheel be centered using tie-rods. Technician B says that it should be centered by removing the steering wheel and putting it back on straight. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 17

13)The term MOST-Likely used to describe the difference between alignment settings from side to side is:

A) toe angle
B) steering pull
C) spread
D) torque steer

Question 18

19)A vehicle's ____________________ is a line drawn between the center of the front axle and the center of the rear axle.

Question 19

5)Front wheel bearings on rear-wheel-drive vehicles do not wear out very often. However, bearing misalignment can be caused by a bent spindle; this increases the load on the bearing.

Question 20

14)____ is formed by the thrust line and the geometric centerline.

A) Bump steer
B) Steering pull
C) Spread
D) Thrust angle

Question 21

21)How would you diagnose excessive toe on a worn tire?

Question 22

22)How would you perform a tire check?

Question 23

24)Why are front-wheel-drive vehicles usually set with zero toe or a slight amount of toe-out?

Question 24

25)If the steering wheel is not straight ahead when driving, what procedure would you use to straighten it?

Question 25

23)How would you conduct a power steering check?
