Q11When replacing a pitman arm on a heavy truck, what is the most important consideration?
✓ Correct answer: B. Proper alignment with sector shaft splines
When replacing a pitman arm, ensuring proper alignment with sector shaft splines is crucial as improper installation can lead to steering misalignment and potential failure.
Q12A truck requires excessive steering effort at low speeds but operates normally at highway speeds. What is the most likely cause?
✓ Correct answer: A. Low power steering pump flow
Low power steering pump flow is most likely to cause excessive steering effort specifically at low speeds because more hydraulic assistance is needed during slow-speed maneuvering when the steering wheel is turned more quickly.
Q13When inspecting a steering column, looseness is detected. Technician A says this could be caused by worn support bearings. Technician B says this could be caused by loose mounting bolts. Who is right?
✓ Correct answer: D. Both Technician A and B
Both technicians are correct. Steering column looseness can be caused by worn support bearings in the column assembly or by loose mounting bolts that secure the column to the vehicle structure.
Q14After replacing the steering gear on a medium-duty truck, which of the following should be performed to ensure proper operation?
✓ Correct answer: C. Check and adjust poppet valve settings
After steering gear replacement, checking and adjusting poppet valve settings is essential to ensure proper pressure relief at full steering wheel rotation and prevent damage to the steering system.
Q15The power steering system on a heavy truck is noisy during operation. After checking and confirming proper fluid level, what should be checked next?
✓ Correct answer: B. Belt condition and tension
After confirming the fluid level is correct, the belt condition and tension should be checked next as a loose or worn belt can cause power steering pump noise during operation.
Q16What is the proper procedure for removing air from a hydraulic power steering system?
✓ Correct answer: A. Run the engine at idle with steering wheel turned from lock to lock several times
The proper procedure for removing air from a hydraulic power steering system is to run the engine at idle with the steering wheel turned from lock to lock several times, which purges air from the system.
Q17When performing a calibration of a column-mounted electronically controlled steering system, what must be done first?
✓ Correct answer: D. Center the steering wheel precisely
Before calibrating a column-mounted electronically controlled steering system, the steering wheel must be centered precisely to establish the correct neutral position for the electronic control module.
Q18A hydraulically assisted steering system exhibits intermittent power assist. Technician A says a worn pump drive belt could cause this issue. Technician B says a faulty pressure relief valve could cause this issue. Who is right?
✓ Correct answer: C. Both Technician A and B
Both technicians are correct. A worn pump drive belt can slip intermittently, causing fluctuating hydraulic pressure, and a faulty pressure relief valve can open inconsistently, both resulting in intermittent power assist.
Q19What is the most likely cause of a steering system that chatters when turning in both directions?
✓ Correct answer: B. Low fluid level in the power steering system
Low fluid level in the power steering system is the most likely cause of chattering when turning in both directions, as it leads to air being drawn into the pump and hydraulic system.
Q20When checking the mounting of a rack-and-pinion steering gear, what is most important to inspect?
✓ Correct answer: A. Condition of bushings and bracket integrity
When inspecting rack-and-pinion mounting, checking bushings and bracket integrity is most important because deteriorated bushings or damaged brackets allow excessive movement of the steering gear, affecting steering precision and feel.
