A driver of a vehicle equipped with a rack and pinion steering gear complains that the
steering wheel jerks whenever the vehicle is being driven into a curbed driveway.
Technician A says that the rack and pinion gears may have too little clearance between
the teeth of the gears. Technician B says that a lack of lubrication of the rack and pinion
is the most likely cause. Which technician is correct?
Niether jerks

says that a relay is commonly used to control horn operation. Which technician is
correct?
Tech B only horn

Nirtogen
Technician A says that a flexible coupling may be used to connect the steering shaft to
the gear input shaft. Technician B says that if the coupling breaks the steering will have
a loose feel. Which technician is correct?
Both techs coupling

collapsible steering columns. Technician B says that a hammer should be used to install
a steering wheel onto the steering shaft. Which technician is correct?
A only collapsible
Which component is NOT a safety requirement for steering column systems?

wiper and washer switch, and the headlight dimmer switch. Technician B says that the
ignition switch is built into the lock cylinder. Which technician is correct?
Tech A only switch
What component locks the steering wheel in place when the driver removes the key?
Lock plate
Technician A says that the front wheels are able to rotate through 60-80 degrees of
rotation. Technician B says that turning the steering wheel all the way left then all the
way right is turning the wheel "lock to lock." Which technician is correct?

The pinion
The spring rate of a spring is measured in units of ________.
lb. per inch
Two technicians are discussing torsion bars. Technician A says that many torsion bars
are adjustable to allow for ride height adjustment. Technician B says that torsion bars
are usually marked left and right and should not be switched side to side. Which
technician is correct?
Both torsion

Wheels and tired
Two technicians are discussing MacPherson struts. Technician A says that in most
applications the entire strut assembly rotates when the front wheels are turned.
Technician B says that a typical MacPherson strut suspension system uses only one
control arm and one ball joint per side. Which technician is correct?

vehicle that is sagging down. Technician B says that replacement springs will be
required to restore the proper ride height. Which technician is correct?
Tech b only proper ride height
What suspension component is used to counteract body lean during cornering?
Stabilizer bar
Two technicians are discussing air shocks. Technician A says that air is forced through
small holes to dampen the ride. Technician B says that air shocks are conventional
hydraulic shock absorbers with an airbag to control vehicle ride height. Which technician
is correct?
Tech B only air shocks
The owner of a pickup truck wants to cut the coil springs to lower the vehicle.
Technician A says that the ride will be harsher than normal if the springs are cut.
