final exam

1

Technician A says if the front wheels have a toe-out condition, the distance between the front edges of the tires is greater than the distance between the rear edges of the tires. Technician B says many front-wheel drive cars have a slight toe-out setting because driving forces tend to move the front wheels to a toe-in position. Who is correct?

2

Excessive toe-in on the front wheels causes wear on the inside edge of the tire treads.

3

An incorrect SAI angle may be caused by a strut tower that is out of position.

4

When removing a coil spring from a strut, some spring tension should be left on the upper strut mount before loosening the strut rod nut.

5

Types of ball joint mounting in the lower control arm include all of these EXCEPT:

6

A spring-loaded seal compensates for ALL of these conditions EXCEPT:

7

The tread wear indicator bar becomes visible when tread depth is less than?

8

Tread wear ratings on a tire allow customers to compare:

9

The thrust line is an imaginary line positioned at a 90 degree angle to the rear wheel centerline and projected forward.

10

Technician A says in a torsion bar front suspension, the front end of the torsion bar is always attached to the upper control arm. Technician B says in a torsion bar front suspension, a torsion bar adjustment mechanism is mounted where the rear end of the torsion bar is attached to the chassis. Who is correct?

11

Technician A says that in some short-and-long arm front suspension systems, the coil springs are mounted between the lower control arm and the chassis. Technician B says that in this type of suspension system, the upper ball joints are the load-carrying ball joints. Who is correct?

12

Excessive heat buildup in a tire may be caused by:

13

Shock absorbers control spring action.

14

Technician A says decreased steering effort may be caused by sagged rear springs. Technician B says sagged rear springs may cause fast steering wheel return. Who is correct?

15

Technician A says the ball joint is pressed into the lower control arm in some independent rear suspension systems. Technician B says when tightening the lower control arm to chassis retaining bolts on independent rear suspension systems, the vehicle weight should be resting on the tires. Who is correct?

16

In some front suspension systems, torsion bars perform the same functions as coil springs.

17

Technician A says a tire pressure check is not required before a wheel alignment. Technician B says a front wheel bearing play should be checked before a wheel alignment. Who is correct?

18

A technician notices during a road test for a pulling complaint that the steering wheel is slow to return to center and requires higher than normal steering effort. The most likely cause of this condition could be:

19

Tapered roller bearings and their matching inner races must be replaced as a set.

20

A tire puncture greater than a 1/4 inch can be repaired.

21

The most likely cause of excessive body lean and sway while cornering is:

22

Technician A says the purpose of a bearing may be to support and guide a pivot. Technician B says the purpose of a bearing may be to support a load and reduce friction. Who is correct?

23

Improper riding height affects other suspension alignment angles.

24

The main function of a shock absorber or strut is to:

25

Some current vehicles have aluminum steering knuckles to reduce unsprung weight.

26

It is not necessary to support any suspension component when replacing a shock absorber or strut.

27

When installing replacement tires:

28

Struts perform the same function as shock absorbers; however, struts may also support the top of the steering knuckle.

29

Improper caster adjustment results in feathered tire wear.

30

A parallelogram steering linkage is used with rack and pinion steering gears.

31

A dial indicator is used to measure integral wheel bearing hub endplay.

32

Shock absorbers and struts provide all of these functions EXCEPT:

33

Gas-filled shock absorbers should extend when disconnected.

34

A customer complains of a steering wheel shake on a rear-wheel-drive vehicle that occurs at speeds between 50 and 60 mph. What is the most likely cause of this complaint?

35

Excessive rear chassis lateral movement may be caused by:

36

A vehicle exhibits excessive tire squeal during cornering. Technician A says that there may be an incorrect toe-out-on-turns angle. Technician B says that a steering arm may be bent. Who is correct?

37

Technician A says a ball joint stud could become broken if there is an out-of-round taper in the steering knuckle mounting hole. Technician B says a ball joint stud could become broken if the ball joint nut was incorrectly torqued. Who is correct?

38

Some independent rear suspension systems have a ball joint that attaches the lower control arm to the bottom of the knuckle.

39

A long, tapered brass punch may be used to remove the bearing races from a serviceable hub.

40

In a rack and pinion steering gear, the rack maintains the tie rods in parallel position in relation to the lower controls arms.

41

A defective track bar may cause rear chassis waddle.

42

Power rack and pinion steering gear operation are being discussed. Technician A says the position of the rotary valve inside the spool valve directs the fluid to the appropriate side of the rack piston. Technician B says during a right turn, fluid is directed to the right side of the rack piston and the rack is moved to the left. Who is correct?

43

All of these statements about lip seals are true EXCEPT:

44

All of the following are advantages of a four-wheel alignment EXCEPT:

45

Technician A says front riding height is reduced by worn control arm bushings. Technician B says front curb riding height is reduced by weak coil springs. Who is correct?
