chapter 10

The vertical side of the frame is called the web.

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?

3

Technician A says a variation of 4 degrees between the right and left SAI angles is satisfactory. Technician B says the average SAI angle on a MacPherson strut front suspension is 12 degrees to 18 degrees. Who is correct?

4

All of these statements about SAI angle are true EXCEPT:

5

The turning radius angle on the outside wheel is more than the turning radius angle on the inside wheel.

6

The right-front wheel setback is excessive on a MacPherson strut front suspension system. The most likely cause of this problem is:

7

A frame may have any of these types of members EXCEPT:

8

Frame sag is the result of frame rails being bent downward in relation to the center of the frame.

9

Technician A says steering pull when braking may be caused by unequal SAI angles on the front suspension. Technician B says front tire tread wear may be caused by unequal SAI angles on the front suspension. Who is correct?

10

An incorrect SAI angle on a MacPherson strut front suspension may be caused by all of these defects EXCEPT:

11

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?

12

Rear axle offset may be caused by:

13

Vehicle directional stability is provided by proper rear wheel tracking and wheelbase.

14

Technician A says if the turning radius is not within specifications, tire tread wear is excessive while cornering. Technician B says a bent steering arm causes the turning radius to be out of specifications. Who is correct?

15

On a vehicle with a straight rear axle, the right rear tire exhibits diagonal wipe. The rear toe measurements are left 0.02 and right 1.13. Technician A says that the rear axle may be bent on the right side of the vehicle. Technician B says that the rear axle has shifted to the left. Who is correct?

16

During a wheel alignment, a technician suspects that the front cradle on a front-wheel-drive vehicle may have shifted. If the cradle was shifted from the right to the left, what effect would it have?

17

All of these statements about vehicle tracking are true EXCEPT:

18

A vehicle with a rack and pinion steering system has a complaint of tire squealing when cornering. The most likely cause of this problem is:
