- While aligning a front end, a technician finds the toe out on turns (turning Radius) to
be greater than the manufacturer’s Specs and it has 2.0 degrees difference from the left
side to the right side. Which, if any, of the following could be the cause?
A. Nothing is wrong; the vehicle has a non symmetrical steering design.
B. Bent pitman arm
C. bent tie-rod
D. Both B and C – ANSWER- D. either a bent pitman arm or a tie rod could cause the
specifications for the toe out on turns to be out of spec. Vehilces with non symmetrical
steering systems will have a difference from side to side, but the difference will not
exceed the manufacturer’s specs and it rarely has a greater than 1.5 degrees difference
from side to side. - When checking a tire, a tech find it to have too much radial (up and down) runout.
Tech A says to rotate the tire and wheel assembly on the mounting studs to correct the
problem. Tech B says to rotate the tire on the wheel assembly to attempt to bring the
runout within specs. Who is right?
A. Tech A Only
B. Tech B Only
C. Both A and B
C. Neither – ANSWER- B. Rotating the tire on the wheel will compensate for wheel/tire
differential (positioning the highest spot on the tire at the lowest spot on the wheel.)
Whereas’, rotating the wheel assembly on the mounting studs will have no effect on
runout. - If you readjust camber on the left front strut, which, if any, of these specs might
change
A. Right caster
B. Left toe and total toe
C. SAI
D. None of the above. – ANSWER- B. Readjusting camber will have an affect on the
individual toe for the left wheel as well as the total toe. SAI is not adjustable and
generally, caster is not adjustable either on a strut suspension. - Too much caster on the left front wheel will cause the __
A. vehicle to drift to the left
B. Left tire to wear on the outside edge
C. vehicle to drift to the right
D. left tire to wear on the inside edge. – ANSWER- C. A vehicle will tend to steer or drift
to the side with the least amount of caster. Caster will not cause tire wear, but excessive
camber will cause wear to the inside of outside shoulders of a tire. - A driver says that the front end of his car vibrates up and down while traveling at
most road speeds. Tech A says that too much runout of the front wheels could be the
cause. Tech B says that a static out of balance of the front wheels could be the cause.
Who is right?
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B – ANSWER- C. Both Techs are right. Too much runout or static out of
balance in the front wheels will cause a vibration - A vehicle has front wheel shimmy at low speed and requires increased steering effort.
Tech A says that too much positive camber could be the cause. Tech B says that too
much Positive caster could be the cause. Who is right?
A Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B – ANSWER- B. Excessive positive caster will increase steering effort,
cause the steering wheel to return too rapidly. cause wander at high speed and shimmy
at low speed. - All of these could cause tire wear if not within manufacturer’s Specs EXCEPT:
A. Caster
B. Wheel balance
C. Toe-In
D. Camber – ANSWER- A. Caster that is out of spec will affect steering and handling
characteristics, but will not cause tire wear. Whereas, too much toe in or out would
severely wear the tires. Additionally, excessive camber would cause inside or outside
shoulder wear on the tire, depending on whether the camber was too negative or
positive. - A vehicle with variable assist power steering has a lack of power assist in both
directions. Tech A says That the problem is in the electronic control system. Tech B
says that there could be a problem in the steering gear or a bad power steering pump.
Who is right?
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B – ANSWER- B. Although further diagnosis will be necessary, Tech B is
right. Tech A is wrong because, when there is a malfunction in a variable assist power
steering system, the system will allow full power steering. - A customer complains that a vehicle wanders on a bumpy road and needs continual
driver correction to stay straight. What could be Wrong?
A. Excessive negative front caster
B. Insufficient front toe
C. Rear or front bump steer
D. All of the above – ANSWER- D. Excessive negative caster, insufficient front toe, and
front or rear bump steer could cause a vehicle to wander on a bumpy road.
- A pressure test is being performed on a car with power steering. The pressure
readings taken when the wheels are at the right and left stops are below specs. The
tester readings are normal when the tester shutoff valve is closed. tech A says that
these readings could be caused by a bad steering gear. tech B says that a bad pump
could cause these readings. Who is right?
A. Tech A Only
B. Tech B Only
C. Both A and B
D. neither – ANSWER- A. A bad steering gear would cause the readings to be low when
the steering is at the right and left stops, but the readings would be normal with the
tester shutoff valve closed. - a vehicle with a manual rack and pinion steering gear has a shimmy. Tech A says
that worn rack to frame mounting bushings could be the cause. tech B says that loose
inner or outer tie rod ends (sockets) could be the cause. Who is right? – ANSWER- C.
Both Techs are right. Steering play or looseness may occur if the rack to frame
mounting bushings are worn, or if the inner or outer tie rod ends are loose. both of these
conditions can result in a shimmy. - The ball joints on a Macpherson strut- type suspension are being replaced. Tech A
says that coil spring compressor should be installed before separating the control arm
and the spindle. Tech B says that the wheel alignment should be checked after the ball
joints have been replaced. Who is right?
A. tech A Only
B. Tech B Only
C. Both A and B
D. Neither – ANSWER- B. The wheel alignment should be checked after the ball joint (or
any suspension part) is replaced. It is not necessary to install a coil spring compressor
prior to separating the control arm and the spindle because the MacPhearson strut
assembly contains a spring. However, a spring compressor should be used if the strut is
being disassembled. - The rear thrust line reads to the left (drivers side) while the vehicle is at normal ride
height. If the wheels were pointing straight ahead, which direction would the vehicle
tend to wander
A. Veer to the left
B. Veer to the right
C. Wander to both left and right
D. No change occurs – ANSWER- B. If the thrust line is to the left and the steering
wheel is held straight, the vehicle will veer to the right. This happens because the rear
wheels will travel towards the left, Which will force the front of the vehicle to the right.
