A) The steering box converts the rotarian motion of the steering wheel to angular motion B) Staring linkage connects the steering Box to the steering arm C) The steering system provides control over the vehicles direction of travel D) Steering knuckle pivots on bushings - Answers The steering provides control over the vehicle's direction of travel Choose the correct statement. A) Turning the steering wheel rotates the pinion and moves the rack up and down B) In most steering racks the teeth on both the pinion and the rack are helical gears C) A large pinion means the number of turns of the steering wheel is increased D) The steering ratio is the same on all vehicles - Answers A large pinion means the number of turns of the steering wheen is increased In an electronic power steering system, PCM stands for? - Answers Power train control module Tech A says that no matter what way the vehicle turns, the inside wheel must always turn less sharply than the outside wheel. Tech B says that Ackermann principle angles the steering arms toward the center of the rear axle. Who is correct? - Answers Tech B Only Tech A says that rack and pinion steering systems generally do not use power steering due to their lighter duty construction. Tech B says that rack and pinion steering systems use a worn gear arrangement to move the rack. Who is correct? - Answers Neither A or B Tech A says that some manufacturers specify automatic transmission fluid in their power steering system. Tech B says that in a power steering system, the force needed to steer the wheel is created by hydraulic pump or electric motor. Who is correct? - Answers Both A and B Tech A says that the clock spring(spiral. cable) assists the turning of the steering wheel on vehicle with EPS. Tech B says that the clock spring is used to transmit an electrical signal to the driver's side airbag. Who is correct? - Answers Tech B Only Tech A says that in most vehicles the steering column uses one or more flexible joints to connect to the steering gearbox. Tech B says that the pitman arm is bolted to the frame and relays the steering linkage movement to the opposite wheel from the steering gearbox. Who is correct? - Answers Tech A Only? The steering component that is bolted to the frame and relays the steering linkage movement to the opposite wheel from the steering gearbox is? - Answers Idler arm The ackermann principle is applied in steering geometry to? - Answers Navigatea corner without scrubbing The part of the parallelogram steering mechanism that provides the adjustment point for adjusting the toe setting is the? - Answers Adjustment sleeve All of the following can create play in the searing wheel except A) Worn steering gears B) worn tie rod ends C) bent steering arm D looseness in the idler arm - Answers bent steering arm All of the following statements with respect to power steering fluid are true except A) It transmits pressure throughout a vehicles power steering system B) It provides lubrication to the moving parts C) It does not get contaminated so only its level needs checking D) It must be able to perform in any weather conditions - Answers It does not get contaminated so only its level needs checking Tech A says that a pickle fork is used to hold a tie rod while it is being tightened. Tech B says that in outer tie rod end should have a noticeable side to side play if it is ok. Who is correct? - Answers Neither A or B Tech A says that in the steering system, play generally results from worn ball sockets and bushings. Tech B says that hard steering is typically caused by tire pressure that is too high. Who is correct - Answers Tech A only Tech a says that many power steering pump pulleys are typically held in place by a press fit. Tech B says that some power steering pump pulleys are made out of plastic. Who is correct? - Answers Both A and B Tech a says that to properly check a tie rod end, the technician should twist the tie rod end, and any rotational movement means the joint is bad. Tech B says that when checking a tie rod, any side to side movement in the joint means the rod is bad. Who is correct? - Answers Tech B only Take a says that when replacing a clock Spring, you should turn it all the way to either end and then install it in the steering column. Tech B says that clock Springs are used to return the steering wheel to its centered position. Who is correct? - Answers Neither A or B Tech A says that worn tie rod ends can cause a steering wandering comaint. Tech B says that a hard steering could be caused by a worn power steering pump.
