Question 1

_______ is the undesired condition produced when, upon hitting a bump, the vehicle darts to one side as the steering linkage is pushed and pulled as a result of the travel of the suspension.
A) Bump steer
B) Road bump
C) Road crown
D) Beam steer

Accepted Answer

Bump steer is the term used to describe the condition where the vehicle's wheels steer themselves without input from the driver, often due to suspension movement when hitting a bump.

Question 2

Technician A says torque-steer is caused by low tire pressure. Technician B says steering return concerns may be caused by binding components. Who is correct?
A) Technician A
B) Technician B
C) Both Technician A and Technician B
D) Neither Technician A nor Technician B

Accepted Answer

Technician B is correct because steering return concerns can indeed be caused by binding components, which can prevent the steering wheel from returning to its neutral position smoothly. Torque-steer, however, is typically related to differences in drive axle lengths or power distribution in front-wheel-drive vehicles, not low tire pressure.

Question 3

Technician A says pull is felt when the driver feels the steering wheel wanting to go to one side. Technician B says drift is when the driver is holding the steering wheel steady and straight but the vehicle slowly begins to move either right or left. Who is correct?
A) Technician A
B) Technician B
C) Both Technician A and Technician B
D) Neither Technician A nor Technician B

Accepted Answer

Technician A is correct in describing "pull" as a condition where the steering wheel wants to go to one side. Technician B is correct in describing "drift" as a condition where the vehicle slowly moves to one side even when the steering wheel is held steady.

Question 4

Technician A says steering return problems describe the condition that occurs when the steering wheel does not return to straight ahead after a turn, also known as memory steer. Technician B says steering return can be caused by binding at pivot points or can be the result of insufficient positive caster. Who is correct?
A) Technician A
B) Technician B
C) Both Technician A and Technician B
D) Neither Technician A nor Technician B

Accepted Answer

Technician A is correct in describing steering return problems as memory steer. Technician B is also correct in stating that binding at pivot points or insufficient positive caster can cause steering return issues.

Question 5

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

Accepted Answer

Bouncing the car is a common method to check the condition of shocks, regardless of whether the car is rear-wheel-drive or not.

Question 9

When checking for a bad shock absorber, you should look for all of the following, EXCEPT:
A) broken shock mount.
B) excessive oil leakage.
C) worn-out bushings.
D) fluid level at the full mark.

Accepted Answer

A full fluid level is normal and not an indication of a bad shock absorber.

Question 10

Worn outer tie-rod ends should be removed from the steering arm/knuckle by all of the following, EXCEPT:
A) removing the cotter pin in the stud and nut.
B) removing the nut from the threads.
C) using the special puller tool to press it out of the taper.
D) heating the arm with a torch to expand the hole diameter.

Accepted Answer

Heating the arm with a torch to expand the hole diameter is not a recommended or safe method for removing tie-rod ends, as it can damage the components and affect the integrity of the steering system.

Question 11

All of the following are true about rubber stops; EXCEPT:
A) they are typically rubber bumpers to prevent metal to metal contact
B) they do their job when suspension parts reach their limit of travel
C) they are typically only on heavy American vehicles
D) they reduce shock to the driver when bottoming out occurs

Accepted Answer

Rubber stops are not exclusive to heavy American vehicles; they are used in various types of vehicles worldwide to prevent metal-to-metal contact and reduce shock.

Question 12

Technician A says you can replace the bushings in some control arms. Technician B says on some vehicles, you have to replace the entire control arm to repair control arm bushings. Who is correct?
A) Technician A
B) Technician B
C) Both Technician A and Technician B
D) Neither Technician A nor Technician B

Accepted Answer

Both Technician A and Technician B are correct because, depending on the vehicle design, some control arms allow for bushing replacement, while others require the entire control arm to be replaced.

Question 13

Vehicle wander may be caused by what?
A) Worn joints and bushings
B) Looseness in steering and suspension components
C) Caster angle is off
D) All the above

Accepted Answer

Vehicle wander can be caused by worn joints and bushings, looseness in steering and suspension components, and incorrect caster angle, making all the options correct.

Question 14

Tech A says torque steer is caused by low tire pressure. Tech B says steering return concerns may be caused by binding components. Who is correct?
A) Tech A
B) Tech B
C) Both Techs A and B
D) Neither Tech A nor B

Accepted Answer

Tech B is correct because steering return concerns can indeed be caused by binding components. Torque steer is typically caused by differences in drive shaft lengths or unequal weight distribution, not low tire pressure.

Question 15

You can check for noises in all these ways EXCEPT:
A) driving over bumps.
B) the use of chassis ears.
C) racing the engine up and listening for noise.
D) using an assistant to bounce the car up and down while you check for parts.

Accepted Answer

Racing the engine up and listening for noise is not a method to check for noises related to the chassis or suspension, as it primarily focuses on engine-related sounds.

Question 16

Tech A says stabilizer bars rarely give problems. Tech B says a broken stabilizer bar will cause a vibration. Who is correct?
A) Tech A
B) Tech B
C) Both Techs A and B
