Homework 2 Wheel and Alignment. Chapter 25 Page: 760
Question: 9 All of the following are causes of failure of a vehicle to track properly, EXCEPT: a) broken or shifted main leaf spring. b) loose or broken spring center or U-bolts. c) worn suspension bushings for springs and torque rods. d) worn tires.
Page 761: Questions:
1. Technician A says a key function of axles is to maintain the position of the wheels relative to each other and the vehicle body. Technician B says there are two main categories of axles which are drive and no-drive. Who is correct? a) Technician A. b) Technician B. c) Both Technician A and B are correct. d) Neither Technician A nor Technician B.
2. Technician A says the steering knuckle enables the articulation of the wheel end. Technician B says the steering knuckle is connected to the I-beam through the master pin. Who is correct?
a) Technician A
b) Technician B
c) Both Technician A and B are correct
d) Neither Technician A nor Technician B
7. Technician A says caster can be adjusted by heating and slightly bending the axle. Technician B says caster can be adjusted by using tapered shims placed between the suspension springs and the axle. Who is correct?
a) Technician A is correct
b) Technician B is correct
c) Both Technician A and B
d) Neither Technician A nor Technician
8. Technician A says when travelling forward, toe should be zero degrees to prevent tire wear. Technician B says too much toe-in will wear the inside edges of tires. Who is correct?
a) Technician A
b) Technician B
c) Both Technician A and B
d) Neither Technician A nor Technician B
9. Technician A says the Ackerman angle refers to a steering principle that states the inner wheel should have a smaller turning angle than the outside wheel because it has a smaller turning radius. Technician B says the Ackermann angle producing toe-out on turns is an adjustable angle. Who is correct?
a) Technician A
b) Technician B
c) Both Technician A an B
d) Neither Technician A nor Technician B
Chapter 28 Page 878 Questions:
2. A driver complains the steering wheel moves violently whenever the vehicle encounters a bump in the road. Which of the following is the most likely problem?
a) An out-of-phase steering column
b) Air in the steering gear
c) Incorrect vehicle alignment angles
d) A misadjusted tie-rod
3. A shock absorber-like device is attached to the tie-rod. What of the following is most likely the purpose of the device?
a) Helps center the steering wheel
b) Minimizes road shock and vibration to the driver
c) Minimizes caster shimmy
d) Prevents bump steer
4. Which of the following is the most likely problem if a steering tire contacts a drag link on sharp right turns?
a) A misaligned steering column
b) A steering wheel off center
c) A drag link that is adjusted to the wrong length
d) An incorrectly adjusted steering stop
5. What is the most likely cause for a power steering reservoir to overflow with oil?
a) A defective power steering pump drive shaft seal
b) Air in the steering gear
c) Fluid that has become too hot
d) Mixing engine oil and automatic transmission oil in the reservoir
Chapter 28 Page 879 Questions:
3. Technician A says if the steering effort is high whenever the steering wheel is turned, one of the power steering pressure relief valves in the steering gear is defective. Technician B says if the power flow control valve in the power steering pump is defective, the vehicle will be hard to steer. Who is right?
a) Technician A
b) Technician B
c) Both Technician A and B
d) Neither Technician A nor B
6. Technician A says rack and pinion steering systems do not include tie rods. Technician B says rack and pinion steering systems do not include a pitman arm or a drag link. Who is correct?
a) Technician A
b) Technician B
c) Both Technician A and B
d) Neither Technician A nor Technician B
7. Technician A says the drag link is a steering linkage rod connecting the pitman arm at one end to the upper steering arm at the other. Technician B says, in addition to that basic bridging function, the drag link performs a leveling function. Who is right?
a) Technician A
b) Technician B
c) Both Technician A and B
d) Neither Technician A nor B
8. Technician A says the kingpin passes through the knuckle’s upper arm, through the end of the I-beam and then through the knuckle yoke’s lower arm. Technician B says a snap ring keeps the kingpin in place and locks the pin into position through the center of the I-beam axle. Who is correct?
a) Technician A
b) Technician B
c) Both Technician A and B
d) Neither Technician A nor B
