ASE G1 EXAM WITH 100% CORRECT
ANSWERS
What is a steering damper? - Answer-reduces amount of road shock transmitted up
through the steering column it does the same as a shock absorber but is mounted
horizontally to the steering linkage, one end is to the center link, one is to the frame
Main job of idler arm - Answer-supports the ride side center link and keeps it at the right
height, attached from pitman arm to car frame
What are tie rods? - Answer-final connection between linkage (connected to the inner
tie rod ends) and knuckles has adjusting sleeves and bolts for toe
What is the steering linkage - Answer-connecting parts between steering gear and arms
are attached to front and / or rear wheels that control the direction the car goes the
linkage transfers gear output shaft motion to steering arms, which turns the wheels
What is the pitman arm? - Answer-connects linkage to steering gear at the base of the
column, transmits motion from gear to linkage, which turns the wheels. it also maintains
the height of the center link, which keeps tie rods parallel to control arm movement, and
avoids unsteady toe settings or bump steer.
What is main bearing noise? - Answer-caused by worn bearings on crankshaft / worn
crank dull, steady knock that gets louder when accelerating
What is rod bearing noise? - Answer-caused by worn bearings / crank, misaligned
connecting rods, or lack of lubrication light tap to heavy knocking or pounding at idle or
low load higher speeds
What is piston pin knock? - Answer-caused by: worn piston rings, worn cylinder walls,
lack of lubrication, misaligned connecting rods, worn piston pin sharp metallic rap at idle
or when engine is hot
What is piston ring noise? - Answer-caused by worn piston rings, worn cylinder walls,
lack of lubrication, piston rings not properly expanding high pitched rattle or clicking at
acceleration
What is a timing chain? - Answer-severe knock that increases with engine speed,
caused by loose timing chain
, What is piston slap? - Answer-hollow, bell - like sound that gets louder with
acceleration, caused by excessive piston to wall clearance, lack of lubrication,
misaligned connecting rods, collapsed piston skirt, worn bearings
when brakes are applied, vibration comes from front of car with disc/drum brakes. is it:
unequal tire pressure
binding caliper slides
excess rotor runout
frozen caliper piston - Answer-excess rotor runout
what is the drive train? - Answer-series of parts in your car that make the wheels turn
types: FWD, RWD, AWD, 4WD
what is the chassis ear? - Answer-tool that identifies the cause of a noise during a road
test
binding steering while turning is often caused by - Answer-worn ball joints, binding rack
gear, binding strut mount
what could cause a power steering hiss / whistle - Answer-steering column shaft binding
/ misaligned
damaged / worn steering gear input shaft and valve
power steering pump has high pressure
restricted power steering lines
what could cause steering gear squeak? - Answer-incorrect fluid in system, bad steering
gear rotary seal, bad steering column components, dry ball sockets
sticky steering / poor steering return could be caused by - Answer-binding steering
column u joints
worn / loose steering linkages or tie rod ends
steering gearset too tight or binding
loose / damaged suspension parts
incorrect wheel alignment
binding steering column bearings
unlearned steering angle sensor calibration
what do the springs on a throttle by wire system do? - Answer-1. the stronger spring
opens the throttle plate if pcm loses control of engine speed for limp home operation
2. the other spring closes the throttle
what is yoke lash? - Answer-AKA rack preload
it affects steering harshness, feedback and noise
in order to correct yoke lash, adjust the screw / plug / shim pack out side of the housing
at the junction of pinion and rack
