Q

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

A

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

Q

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?

Q

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?

Q

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

A

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

Q

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

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

Q

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

A

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

Q

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

A

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
