Question 1

The combination of SAI and camber is called the ____________________.

Accepted Answer

The answer of The combination of SAI and camber is...

Question 2

Negative camber is when a tire tilts outward at the top.

Accepted Answer

A) True 
 B)False

Question 3

The term MOST-Likely used to describe the distance at the road surface between the centerline of true vertical at the center of the tire tread and the steering axis pivot centerline is:

Accepted Answer

A)  scrub radius
B)  tracking
C)  oversteer
D)  set-back

Question 4

Which of the following statements is LEAST-Likely true?

Accepted Answer

A)  When the front wheels on a car have different caster settings, the car will pull toward the side with the most positive caster.
B)  Negative caster is when the steering axis tilts forward, moving the point of load behind the wheel.
C)  During a turn, caster can cause the spindle to move either toward or away from the ground, depending on whether the caster is negative or positive.
D)  Caster is a directional control angle but does not cause tire wear when the vehicle is going straight.

Question 5

A change in toe setting does not affect the position of the steering wheel.

Accepted Answer

A) True 
 B)False

Question 6

____________________ is a measurement of the camber angle as it changes during a turn.

Accepted Answer

The answer of ____________________ is a measurement of the camber...

Question 7

Bent steering linkage will cause the toe setting to change. This affects the position of the steering wheel, which will now be off-center when traveling straight.

Accepted Answer

A) True 
 B)False

Question 8

What are some of the possible causes of incorrect scrub radius?

Accepted Answer

When tires and wheels that are too tall ...

Question 9

____ is the forward or rearward tilt of the spindle support arm.

Accepted Answer

A)  Scuff
B)  Camber
C)  Cradle
D)  Caster

Question 10

Provide definitions for the following terms: wheelbase and tracking.

Accepted Answer

The distance between the front and rear ...

Question 11

When a vehicle makes a turn, the outside wheel must travel in a wider arc than the inside wheel. The alignment angle that controls this is MOST-Likely called:

Accepted Answer

A)  set-back
B)  scrub radius
C)  turning radius
D)  tie-rod C

Question 12

What is the function of steering axis inclination (SAI)?

Accepted Answer

SAI has three functions:
1. After a turn, SAI helps the vehicle return to straight ahead.
2. SAI keeps the vehicle going straight down the road. Although positive caster does this as well, more positive caster makes it harder to steer.
3. SAI allows the vehicle to have less positive caster (for easier steering) while still having good directional stability.

Question 13

Which of the following statements is LEAST-Likely true?

Accepted Answer

A)  Scrub radius is a factor of steering axis inclination.
B)  Scrub radius is the pivot point for the front tire's footprint.
C)  The junction of the steering axis and centerline pivot point is normally below the surface of the road.
D)  RWD vehicles generally have negative scrub radius. D

Question 14

____________________ is the inward or outward tilt of a tire at the top

Accepted Answer

The answer of ____________________ is the inward or outward tilt...

Question 15

Every 1/16" of toe-in results in 11 feet per mile of ____________________.

Accepted Answer

The answer of Every 1/16" of toe-in results in 11...

Question 16

What are some of the possible causes of incorrect toe?

Accepted Answer

Several things can cause incorrect toe:
...

Question 17

____________________ is the alignment angle most responsible for tire wear.

Accepted Answer

The answer of ____________________ is the alignment angle most responsible...

Question 18

While having a discussion, Technician A says that if there is a tire blowout on the left side of a front-wheel-drive vehicle with positive scrub radius, the tire will pull hard to the left. Technician B says that it will pull hard to the right. Who is correct?

Accepted Answer

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

Question 19

All of the following statements are true EXCEPT:

Accepted Answer

A)  a cambered tire tends to roll in a circle, as if it were at the large end of a cone.
B)  positive camber is when a tire tilts inward at the top.
C)  the camber angle is controlled by the position of the control arms or struts.
D)  unequal camber between tires on opposite sides of the vehicle can cause a steering pull to the side with the most camber.

Question 20

While having a discussion, Technician A says that when a vehicle has four-wheel alignment capability, the tendency to oversteer can be minimized by adjusting the camber on the rear wheels to a more negative setting than the front wheels. Technician B says that when tires of different profiles are installed on the same vehicle, the tires of the lower height are installed on the rear to prevent oversteer. Who is correct?

Accepted Answer

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