Q

A customer complains that power steering assist stops when driving in the rain. What is the most likely cause?
A. The steering linkage tie rod ends are getting wet causing a bind
B. Water is getting into the power steering fluid through the high-pressure hose
C. Moisture is getting into the steering gears displacing the lubricant
D. The power steering pump drive belt is loose or defective

Q

A tie rod end is being replaced. Tech A says the steering wheel may be crooked when driving straight and excessive tire wear can occur if an alignment is not preformed. Tech B says that the power steering system should be bled after the tie rod is installed. Which tech is correct?
A. Tech A
B. Tech B
C. Both techs
D. Neither tech

18
Q

A power steering pump is being tested using a pressure gauge. The pressure increases to the specified value when the valve is closed restricting the flow of fluid to the steering gear. The pressure only rises a little when the steering wheel is turned all the way to the left or right with the valve open. Tech A says that the pump is weak and should be replaced. Tech B says that the steering gear is defective and should be replaced. Which technician is correct?
A. Tech A
B. Tech B
C. Both techs
D. Neither tech

Q

Which of the following is least likely to cause loose steering?
A. A loose pitman arm retaining nut
B. A worn idler arm
C. A worn center link
D. A loose tie rod end

20
Q

Power steering fluid is observed dripping out of the boots of the power rack-and-pinion steering gear assembly. What is the most likely cause?
A. A loose or worn inner tie rod end (ball-socket assembly)
B. Leaking control valve seals
C. A leaking inner rack seal
D. A loose stub U-joint

Q

Two technicians are discussing airbags. Tech A says that the airbag should be disabled when service work is going to be performed on the steering column or related components. Tech B says that the connector(s) are yellow. Which tech is correct?

Q

A customer complains that the steering on a vehicle equipped with a conventional power steering gear is hard to steer at times. Which is the least likely cause?
A. A loose power steering belt
B. A defective intermediate shaft u-joint
C. Loose tie rod ends
D. A defective ball joint(s)

23
Q

How is the rack support usually adjusted in a rack-and-pinion steering gear?
A. No adjustment necessary- just thread into the rack assembly
B. Torque to 80-100 ft-lbs
C. Tighten and back off 60 degrees
D. Tighten until all steering wheel free-play is eliminated

A

C

24
Q

A vehicle owner complains of a binding in the steering when turning and noise when driving over bumps in the road. What is the most likely cause?
A. Worn outer tie rod ends
B. Low power steering fluid level
C. Defective upper strut mount
D. Worn power steering pump drive belt

Q

The power steering fluid is being checked on a vehicle equipped with a rack-and-pinion steering. The fluid is silver/black in color. Tech A says that this is normal for a vehicle equipped with rack-and-pinion steering. Tech B says that the rack and pinion gear teeth must be worn because the silver color is likely a result of the wear metals. Which tech is correct?
