Chapter 78 ASE questions at end of chapter
A car is brought into the shop with excessive steering wheel play. Technician A checks for worn ball sockets. Technician B checks the condition of the system’s idler arm. Who is right?
A, B, Both, Neither
Steering wheel play is normally caused by worn ball sockets, a worn idler arm, or too much clearance in the steering gearbox.-Pg 1561
Answer: Both
A car’s steering wheel turns three inches before causing movement on the front wheels. Technician A tells the owner of the vehicle that this indicates normal play in the steering system. Technician B tells the owner of the vehicle that this indicates excessive steering wheel play. Who is right?
A, B, Both, Neither
Typically, you should not be able to turn the steering wheel more than about 1 1/2 in without causing movement of the front wheels. If the steering wheel rotates excessively without moving the wheels, a serious steering problem exists. - Pg 1561
Answer: Tech B
Lubricant is leaking from a car’s power steering system. Technician A says that, if equipped, a dipstick attached to the reservoir cap can be used to measure power steering fluid level. Technician B says that a cracked reservoir could be the source of the leakage. Who is right?
A, B, Both, Neither
Power steering fluid is lubricant- Goose
Answer: Both
An automobile has a “hard steering” problem. Technician A checks the steering gearbox for problems. Technician B inspects the suspension system for problems. Who is right?
A, B, Both, Neither
Hard steering (steering that requires excessive effort) can be caused by problems with the steering gearbox, the rack-and-pinion steering gear, the power steering components, the ball sockets, and the suspension system. - Pg 1562
Answer: Both
Noise is coming from a steering pump. Technician A checks the inner tie-rod ends. Technician B checks the pump’s fluid level. Who is right?
Power steering pump noise is usually a loud whine that only occurs when you turn the steering wheel. It is often due to a low fluid level and air in the system. -Pg 1563
Answer: Tech B
An automotive power steering system’s fluid level needs to be checked. Technician A checks the steering system’s fluid level with the engine off. Technician B checks the fluid level while the engine is running. Who is right?
To check the level of fluid in the power steering system, the engine should NOT be running. Set the parking brake and place the transmission in park or in neutral.-Pg 1563
Answer: Tech A
Technician A says the alignment of the front wheels is changed when a tie-rod is changed. Technician B says that during steering wheel and air bag removal, it is recommended to keep the vehicle battery connected. Who is right?
A, B, Both, Neither
The alignment of the front wheels is altered when the length of a tie-rod is changed. pg 1566
After tie-rod service, always check toe for proper adjustment. - pg 1566
Before servicing the steering wheel, disconnect the battery to prevent accidental air bag deployment. - pg 1565
Answer: Not sure, definitely not Tech B, but judge for yourself, too ambiguous since question talks about if the tie-rod is changed, while book talks about if tie-rod length changes. Toe is part of alignment, which made me think maybe yes
A car’s power steering belt is loose. Technician A says the belt may be worn and stretched and might require replacement. Technician B says the belt tensioner may be broken and unable to apply enough tension to the belt. Who is right?
A, B, Both, Neither
A worn or cracked belt may snap, causing a loss of power assist. Always inspect the belt very closely. - pg 1564
To remove a serpentine belt, use a breaker bar to swing the belt tensioner sideways and release tension. Pull the belt off its pulleys. Check the condition of all idler pulleys by spinning them with your fingers. If any feel dry or rough, replace the pulley. Damaged, worn, or loose idler pulleys can cause the new belt to fail prematurely. - pg 1564
Answer: Both, according to Goose
An automobile’s steering column needs servicing. Technician A tells the owner of the car that most steering columns can be repaired with the column mounted in the car. Technician B tells the owner of the car that most steering columns must be removed from the vehicle when service is required. Who is right?
A, B, Both, Neither
Most steering column repairs can be done with the column mounted in the vehicle. However, some repairs require that the steering column be removed. - pg 1564
Answer: Tech A
A car’s steering wheel needs to be removed from its shaft. Technician A uses a hammer and fork punch to perform this service procedure. Technician B uses a wheel puller to perform this service procedure. Who is right?
A, B, Both, Neither
A wheel puller is used to remove a steering wheel from its shaft. - pg 1565
Answer: Tech B
Technician A says that power steering systems are not susceptible to “hard steering” problems. Technician B says that accurately diagnosing an electronic assist steering system requires a scan tool or diagnostic tablet. Who is right?
A, B, Both, Neither
Power steering systems commonly suffer from hard steering. - Pg 1562
Answer: Unsure, for sure not Tech A, possibly not B. No mention of electronic assist steering system diagnostics and repair in chapter.
A car equipped with manual rack-and-pinion steering is brought into the shop with excessive steering wheel play. Technician A adjusts the steering gear. Technician B adjusted the idler arm. Who is right?
A, B, Both, Neither
Steering wheel play is normally caused by worn ball sockets, a worn idler arm, or too much clearance in the steering gearbox (worm and rack-and-pinion types)-pg 1561
Answer: At first thought Both, but now only believe Tech A. Let me explain. Although a worn idler arm can cause steering wheel play, a idler arm is only found in a linkage steering system. This vehicle is a manual rack-and-pinion steering system
An automobile’s power steering pump is not operating properly. Technician A performs a power steering pressure test to check the operation of the power steering pump. Technician B says a power steering pressure test will not detect power steering pump malfunctions. Who is right?
A, B, Both, Neither
A power steering pressure test checks the operation of the power steering pump, pressure relief valve, control valve, hoses, and power piston. pg 1569
Answer: Tech A
A “buzzing” sound is coming from an automobile’s power steering system when the wheel is turned. Technician A tells the owner of the vehicle that this problem may be the result of a damaged pitman arm. Technician B tells the owner of the vehicle that this problem may be caused by air in the power steering system. Who is right?
A, B, Both, Neither
When any of the hydraulic components are serviced, you should bleed the power steering system. Bleeding ensures that all air is out of the lines, pump, and gearbox. Air can cause the power steering system to make a buzzing sound. This sound will occur as the steering wheel is turned to the right or left. - pg 1571
Answer: Tech B
