Question 1

Technician A says a dry-park check places a high load on the steering and suspension components to check for loose joints and other parts.Technician B says to perform a dry-park check, leave the wheels on the lift ramps and have a helper shake the steering wheel rapidly side-to-side while you listen and feel for loose linkage components.Who is correct?

Accepted Answer

Both Technician A and Technician B are correct. A dry-park check does indeed place a high load on the steering and suspension components to identify loose joints and other parts. Additionally, performing a dry-park check as described by Technician B, with the wheels on the lift ramps and shaking the steering wheel side-to-side, is a standard procedure to listen and feel for loose linkage components.

Question 2

A loose power steering belt may cause all of the following problems EXCEPT:

Accepted Answer

A loose power steering belt primarily affects the operation of the power steering pump, leading to erratic assist and noise issues. However, it does not directly cause excessive wear on internal pump parts; that issue is more likely related to other factors like fluid contamination or pump failure.

Question 3

Flushing of the power steering system is performed by disconnecting the fluid ___________ line to the pump.

Accepted Answer

return

Question 4

Technician A says many idler arms are allowed to have a slight amount of play.Technician B says checking the play requires applying a specific amount of force to the arm and measuring the movement with a dial indicator.Who is correct?

Accepted Answer

Both technicians are correct. Technician A is correct in stating that many idler arms are allowed to have a slight amount of play, as this is part of their design to accommodate the movement of the steering system. Technician B is correct in stating that checking the play in idler arms requires applying a specific amount of force to the arm and measuring the movement with a dial indicator, as this is a standard procedure to accurately assess the condition of the idler arm.

Question 5

A customer complaint of hard steering may be caused simply by low tire pressure.

Accepted Answer

Low tire pressure can increase the effort required to turn the steering wheel, leading to complaints of hard steering.

Question 6

The temporary disabling of the supplemental restraint system is being discussed.Technician A says that removing the SRS fuse is not a step in this procedure.Technician B says to unplug the yellow SRS connector at the steering column.Who is correct?

Accepted Answer

Unplugging the yellow SRS connector at the steering column is a step in the procedure for temporarily disabling the supplemental restraint system. Removing the SRS fuse is not a step in this procedure.

Question 7

Technician A says hybrid vehicles currently on the market use the high-voltage system to operate the power steering.Technician B says red wiring and connectors indicate high voltage.Who is correct?

Accepted Answer

Hybrid vehicles typically use electric power steering systems that do not require high-voltage systems, and high-voltage wiring is usually orange, not red.

Question 8

A whining noise when the wheels are turned is usually caused by ________ in the system.

Accepted Answer

The answer of A whining noise when the wheels are...

Question 9

Technician A says electric assist can only be applied at the steering column.Technician B says belts should be inspected during routine service and often require replacement every 60,000 to 90,000 miles.Who is correct?

Accepted Answer

Electric assist can be applied not only at the steering column but also directly to the steering rack or gear, making Technician A's statement incorrect. Technician B is correct as belts are a routine service item and often have a replacement interval of 60,000 to 90,000 miles.

Question 10

To bleed air from a power steering system with the engine running,

Accepted Answer

Turning the steering wheel side-to-side with the engine running is the correct method to bleed air from a power steering system. This action circulates the fluid throughout the system, helping to remove any trapped air bubbles.

Question 11

Technician A says worn strut bearing plates can cause many of the same problems as a worn rack and pinion gearbox.Technician B says tie rods are not a common wear item in steering systems.Who is correct?

Accepted Answer

Technician A is correct because worn strut bearing plates can indeed cause steering issues similar to those caused by a worn rack and pinion gearbox, such as noise, poor handling, and alignment problems. Technician B is incorrect because tie rods are a common wear item in steering systems, as they are crucial for maintaining proper alignment and handling.

Question 12

The steering wheel indicator light is used to warn the driver of a fault in the electric assist system.

Accepted Answer

The steering wheel indicator light, often depicted as a steering wheel symbol or an exclamation mark next to a steering wheel symbol on the dashboard, illuminates to warn the driver of a fault within the vehicle's power steering system, particularly in vehicles with electric power steering assist systems.

Question 13

It is normal for the socket to rotate on its stud; this is not an indication of a problem or faulty joint.

Accepted Answer

The socket is designed to rotate on its stud to allow for movement and prevent binding.

Question 14

Technician A says worn tie-rod ends are a possible cause of wander.Technician B says excessive yoke clearance is a possible cause of wander.Who is correct?

Accepted Answer

Both technicians are correct. Worn tie-rod ends can lead to steering looseness or play, causing the vehicle to wander. Excessive yoke clearance can also contribute to steering play and wander.

Question 15

Replacement of a worn centerlink or relay rod requires separating it from the ________ and idler arms and from the inner tie rods.

Accepted Answer

The answer of Replacement of a worn centerlink or relay...

Question 16

High voltage circuits on hybrid vehicles can be identified by their ___________ color.

Accepted Answer

The answer of High voltage circuits on hybrid vehicles can...

Question 17

Automatic transmission fluid (ATF) may be substituted for power steering fluid in most vehicles.

Accepted Answer

ATF and power steering fluid are different fluids with different properties. ATF is designed for use in automatic transmissions, while power steering fluid is designed for use in power steering systems. Using ATF in a power steering system can damage the system.

Question 18

Power steering belts often require replacement every 50,000 miles.

Accepted Answer

The answer of Power steering belts often require replacement every...
