Answer 1

B

Question 2

Caster is usually referred to as either being ______________ or _____________ depending on whether the angle of the steering axis is pushed forward or pull rearward.

Answer 2

positive, negative

Question 3

Technician A says rear wheel setback may cause the wheelbase dimensions to be different from one side of the vehicle to the other. Technician B says a front wheel setback may be the result of a damaged knuckle and require the replacement of parts. Who is correct?

D) Neither A nor B

Answer 3

C

Question 4

Which of the following is not a part of a MacPherson Strut suspension system?

A) Strut mount
B) Steering knuckle
C) Coil spring
D) Upper control arm

Question 5

The parallelogram steering system is most commonly used on trucks and SUV's.

Question 6

Tires are a primary component of the steering and suspension of a vehicle.

Question 7

Technician A says camber is the inward or outward tilt of the top of the wheel when viewing it from in front or behind the vehicle. Technician B says an incorrect camber angle can cause the vehicle to drift or pull to one side. Who is correct?

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

Question 8

The suspension system supports the weight of the vehicle with the springs.

Question 9

Technician A says the steering arms and tie rod ends are attached to the knuckle which enables the steering action to occur. Technician B says unlike the SLA system, the MacPherson strut suspension system does not have both an upper and lower control arm. Who is correct?

A) Technician A
B) Technican B
C) Both A and B
D) Neither A nor B

Question 10

The vehicle body and most of the other components are supported by the _________________ system.

Question 11

The toe adjustment is used to overcome the tendency of the torque of the _____________________ on front wheel drive vehicles.

Question 12

Excessive toe out will cause severe pre-mature tire _____________ or wear.

Question 13

Rack and pinion steering systems are very popular on smaller vehicles because they are very compact.

Question 14

Technician A says in incorrect toe angle can cause significant tire wear. Technician B says a positive toe angle is desirable on most vehicles for driving stability. Who is correct?

A) Technician A
B) Technican B
C) Both A and B
D) Neither A nor B

Question 15

The term included angle is obtained by adding together the positive ____________ and the SAI.

Question 16

SLA is an abbreviation used to describe a slotted lock angle suspension system.

Question 17

Which of the following would not be a cause of a vehicle to drift to one side or the other?

A) Excessive but equal negative caster
B) 3 degrees positive camber on one wheel and 0 degrees on the opposite wheel
C) 3 degrees thrust angle
D) An unequal toe adjustment

Question 18

Technician A says bump steering can cause the vehicle to dart and dive from side to side after hitting a bump. Technician B says a positive degree in the thrust angle can cause a vehicle to "dog track" as it goes down the road. Who is correct?

A) Technician A
B) Technican B
C) Both A and B
D) Neither A nor B

Question 19

Technician A says the parallelogram steering system has no moveable or wear parts. Technician B says power steering systems can be either hydraulic or electronic. Who is correct?

A) Technician A
B) Technican B
C) Both A and B
D) Neither A nor B

Question 20

Technician A says rear suspension systems use either coil springs or leaf springs. Technician B says an airbag deployment frequently requires replacing the steering wheel. Who is correct?

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

Question 21

Discuss the prominence of properly repairing the steering wheel and column after an airbag deployment.

Question 22

Discuss how an incorrect camber angle will cause a vehicle to drift.

Question 23

Discuss why an improper toe angle will cause such extreme tire wear.

Question 24

Which suspension angles will cause tire wear and why does it occur?

Question 25

Discuss why the thrust angle is such a critical angle.
