Question 1

As a rule, ride height should not vary more than about _________ from side to side or front to rear.

Accepted Answer

one-half inch; 13 mm
one-half inch
13 mm

Question 2

A damaged upper strut plate would cause which of the following suspension noises?
A)clunking
B)creaking or groaning
C)knocking on acceleration
D)knocking over bumps

Accepted Answer

B

Question 3

Control arm bushings are common wear items and require replacement.

Accepted Answer

Control arm bushings are made of rubber or polyurethane and are subject to wear and tear over time due to their role in the suspension system, absorbing shocks and vibrations, thus they commonly require replacement.

Question 4

During an inspection of a ball joint, the wear indicator is found to be receded into the socket housing.What does this indicate?
A)The ball joint needs lubrication
B)The ball joint is excessively worn
C)The ball joint is serviceable
D)The ball joint needs adjusting

Accepted Answer

When the wear indicator is receded into the socket housing, it indicates that the ball joint is excessively worn. This is because the wear indicator's position is designed to show the extent of wear, and its recession is a sign that the joint has worn beyond acceptable limits.

Question 5

A featheredged tire usually indicates incorrect __________.

Accepted Answer

The answer of A featheredged tire usually indicates incorrect __________....

Question 6

If the __________ __________ ________ are broken, the body will pitch or roll much more than normal when turning a corner.

Accepted Answer

The answer of If the __________ __________ ________ are broken,...

Question 7

A tire is being inspected.The technician finds excessive wear on one edge of the tire.Which of the following is the MOST LIKELY cause?
A)underinflation
B)overinflation
C)excessive camber
D)excessive caster

Accepted Answer

Excessive camber causes uneven wear on one edge of the tire because it alters the angle at which the tire contacts the road, leading to more pressure and wear on one side.

Question 8

Most struts can be serviced without removing them from the vehicle.

Accepted Answer

Most struts need to be removed from the vehicle to be serviced or replaced, as they are integral components of the suspension system that require disassembly from the vehicle for proper inspection, repair, or replacement.

Question 9

Excessive lean or sway is caused by broken sway bar links.

Accepted Answer

Broken sway bar links can lead to excessive lean or sway in a vehicle during turns or when driving over uneven surfaces, as they are crucial for stabilizing the vehicle's body roll.

Question 10

Grease fittings, or Zerk fittings, are large fittings threaded into a component for the injection of grease.

Accepted Answer

Grease fittings, or Zerk fittings, are typically small fittings threaded into a component for the injection of grease, not large.

Question 11

All of the following can cause a clunking noise on acceleration or deceleration EXCEPT:
A)worn control arm bushing
B)worn sway bar link
C)worn ball joint
D)worn CV joint

Accepted Answer

Worn sway bar links typically cause rattling or knocking noises when driving over bumps or during turns, not specifically on acceleration or deceleration. The other options (worn control arm bushing, worn ball joint, and worn CV joint) can cause clunking noises during acceleration or deceleration due to the play or movement in these components.

Question 12

Steering knuckles are subject to damage from ___________.

Accepted Answer

The answer of Steering knuckles are subject to damage from...

Question 13

__________ affects the thrust angle and should be set (if possible) before setting the front wheel alignment.
A)Camber
B)Caster
C)Zero toe
D)Rear toe

Accepted Answer

Rear toe affects the thrust angle and should be adjusted before setting the front wheel alignment to ensure the vehicle drives straight and does not pull to one side.

Question 14

To correct for negative or positive thrust angle, rear wheel _____ is adjusted.
A)camber
B)caster
C)toe
D)suspension

Accepted Answer

To correct for negative or positive thrust angle, rear wheel toe is adjusted. This involves altering the direction that the tires are pointed relative to the centerline of the vehicle to ensure proper alignment and handling.

Question 15

Some manufacturers specify checking ball joint wear may by measuring rotational torque.

Accepted Answer

Manufacturers specify checking ball joint wear by measuring rotational torque to ensure the ball joint is within the acceptable range of tightness and hasn't worn out to the point where it could affect vehicle handling and safety.

Question 16

During an inspection, the spring bumper is found to be shiny.What does this indicate?
A)The bumper needs to be replaced
B)The spring may be weak
C)The shock may be weak
D)Both B and C are correct

Accepted Answer

The answer of During an inspection, the spring bumper is...

Question 17

__________ is the measurement of the distance between the front and rear tires of the same axle.
A)Ride height
B)Caster
C)Camber
D)Toe

Accepted Answer

Toe is the term used to describe the angle and direction at which the tires are set to point relative to a straight-ahead position. It measures the distance between the front of the tires compared to the distance between the rear of the same tires, which affects how the tires wear and the vehicle's straight-line stability.

Question 18

Technician A says that worn dampers will generally bounce more than two to three times when performing a bounce test.Technician B says camber is the angle most responsible for straight tracking of the car.Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct because worn dampers (shock absorbers or struts) losing their ability to control suspension movement will indeed result in the vehicle bouncing more than two to three times when performing a bounce test. Technician B is incorrect because it is the toe angle, not camber, that is most responsible for the straight tracking of a car. Camber affects tire wear and cornering performance.

Question 19

When testing for noises, an electronic ___________ can be very helpful.

Accepted Answer

The answer of When testing for noises, an electronic ___________...

Question 20

When you are replacing gas-charged struts or shocks:
A)the gas charge needs to be released before throwing the strut or shock away
B)you should refer to the shock manufacturer's service information before attempting to release the pressure in the shock
C)a small hole is drilled into the lower section of the strut or shock to allow the gas to escape
D)all of the answers are correct

Accepted Answer

All of the answers are correct. When replacing gas-charged struts or shocks, the gas charge needs to be released before throwing the strut or shock away. You should refer to the shock manufacturer's service information before attempting to release the pressure in the shock. A small hole is drilled into the lower section of the strut or shock to allow the gas to escape.
