d) Negative caster
|
|
|
What type of angle is caster?
a) load bearing b) Directional control c) Tire wearing d) Guide or following |
b). Directional control
|
|
|
The invisible line drawn through the center of the upper and lower ball joints on a conventional steering vehicle is known as the:
a) Steering axis b) Datum line c) Reference line d) Line of caster |
a) Steering axis
|
|
|
Caster will tend to lean the car into a turn if it is set:

d) Negative
|
|
|
Excessive positive caster can cause:
a) Body roll, tire wear and pulling b) Road shock, sensitive steering and bump steer c) Road shock, heavy steering and shimmy d) Shimmy, wander and weave |
c) Road shock, heavy steering and shimmy
|
|
|
Camber is measured by comparing the wheel angle to:
a) true vertical b) caster c) geometric centre line d) thrust line |
a) true vertical
|
|
|
If the wheel on a vehicle leans inwards at the top, the angle produced is called:
a) positive camber b) negative camber c) positive caster d) negative caster |
b) negative camber
|
|
|
Excessive camber may cause:
a) tire wear b) tire feathering c) both a) and b) d) neither a) or b) |
a) tire wear
|
|
|
Uneven side to side camber may cause:
a) tire wear b) excessive body roll c) hard steering d) the car to pull |
d) the car to pull
|
|
|
The inward tilt of the steering axis, view from the front, is called:
a) Negative camber b) Positive camber c) Negative SAI d) Steering axis inclination |
d) Steering axis inclination
|
|
|
The front of the car raises when the wheels are turned in either direction from centre. The probable cause is:
a) uneven caster b) camber out of range c) SAI d) seized ball joint |
c) SAI
|
|
|
When measuring SAI you must also consider:
a) the inward or outward tilt of the wheel b) caster c) Positive camber d) Negative camber |
a) the inward or outward tilt of the wheel
|
|
|
Included angle is defined as:
a) Including caster and camber together b) SAI, camber and caster together c) Steering axis inclination and Camber d) Point of intersection, true vertical and Camber |
c) Steering axis inclination and Camber
|
|
|
When camber is zero (0 degree), SAI:
a) and included angle will be zero (0 degree) also b) and included angle will be the same c) will be positive d) will be negative |
b) and included angle will be the same
|
|
|
Turning radius is determined by:
a) The amount of toe-out on turns b) The steering axis c) How sharp a turn the car can make d) The angle of the steering arms |
d) The angle of the steering arms
|
|
|
Incorrect turning radius may cause:
a) tire squeal b) tire wear c) both a) and b) d) neither a) or b) |
c) both a) and b)
|
|
|
When measuring turning radius, if the outside wheel is turned in 20 degree, the inside wheel should turn:
a) The same to avoid tire wear b) more c) less d) out 18.5 degree |
b) more
|
|
|
Incorrect turning radius is most likely the result of:
a) improper toe-in b) improper toe-out c) excessive tie rod movement d) a bent steering arm |
d) a bent steering arm
|
|
|
If turning radius specs are not published:
a) it is not necessary to measure it b) Measurements should be the same side to side c) The vehicle may not have turning radius d) Use specs from a similar vehicle |
b) Measurements should be the same side to side
|
|
|
The purpose of the toe angle is to:
a) Maximize tire life b) Compensate for any deflection in the steering linkage c) both a) and b) d) neither a) or b) |
c) both a) and b)
|
|
|
When the vehicle is in motion, ideally the toe setting should be:
a) The same front to rear b) zero (0 degree) c) slightly in d) slightly out |
b) zero (0 degree)
|
|
|
Incorrect toe setting may cause:
a) Pull to the side that is most positive b) Instability at high speeds c) rapid tire wear d) a pull to the side that is most negative |
c) rapid tire wear
|
|
|
The last angle to be adjusted when performing a wheel alignment is:
a) toe b) front caster c) rear camber d) SAI |
a) toe
|
|
|
Excessive toe-out causes:
a) Pull to the right b) a pull to the left c) Scuffing wear from outside to inside d) Scuffing wear from inside to outside |
d) Scuffing wear from inside to outside
|
|
|
The vehicle thrust line is determined by the:
a) rear toe b) tracking c) turning radius d) front toe |
b) tracking
|
|
|
If the trust line is off to the right, the vehicle will:
a) pull to the left b) Pull to the side with the shortest wheelbase c) dog track d) All of the above |
d) All of the above
|
|
|
The thrust line is corrected when adjusting:
a) rear camber b) rear caster c) rear toe d) none of the above |
c) rear toe
|
|
|
The trust line should be the same as, or at least parallel to the:
a) geometric centre line b) vehicle centre line c) both a) and b) d) neither a) or b) |
c) both a) and b)
|
|
|
The direction the vehicle will travel in is determined by the:
a) thrust line b) vehicle centre line c) geometric centre line d) all of the above |
d) all of the above
|
|
|
When performing a wheel alignment the order of adjustment is:
a) rear camber and toe, front caster, SAI, turning radius and toe. b) rear camber, rear toe, front and rear thrust line, caster, camber and toe. c) rear camber, rear turning radius, toe, front caster, front camber and toe. d) none of the above |
d) none of the above
|
|
|
Moving the top of the McPherson strut rearward will cause the:
a) caster to move more positive b) camber to move more negative c) casterto move more negative d) camber to move more positive |
a) caster to move more positive
|
|
|
Adding a shim at the top between the rear spindle and Axel will cause the:
a) camber to move more positive b) camber to move more negative c) toe to move more negative d) toe to move more positive |
a) camber to move more positive
|
|
|
Lengthening a front-mounted strut rod will increase:
