Suspension & Steering A4 copy unit 5 Exam Questions With Verified Answers. A typical air bag deployment time is: - answer40 milliseconds Technician A says a bent center link will affect front wheel toe. Technician B says a bent center link willaffect front wheel camber. Who is correct? - answerA Reduced rear curb riding height may cause damaged rear strikeout bumpers. - answerT After a power recirculating ball steering gear is properly adjusted, the steering wheel free play is still excessive. Technician A says the steering gear mounting bolts may be loose. Technician B says the high-pressure power steering hose may be restricted. Who is correct? - answerA A loose worm shaft bearing preload adjustment may cause a rattling noise when driving on irregular road surfaces. - answerF The specified vehicle lift points can be found in a service manual. - answerT On a power steering pump with a variable assist steering actuator, what component controls the actuator: - answerPCM An electronic power steering (EPS) system is being discussed. Technician A says if the engine stalls and the ignition switch is on, the EPS remains operational. Technician B says if the steering wheel is turned and held fully in one direction, the power module reduces current flow through the steering gear motor to prevent motor overheating. Who is correct? - answerBOTH In a MacPherson strut-type rear suspension, the struts are bolted to the top of the spindles. - answerT When the brakes are applied with the doors closed on a vehicle with an electronic air suspension system, the air suspension module ignores all requests from the height sensors. - answerT A fine-toothed file may be used to clean a sticking flow control valve. - answerF In some traction control systems if the control module senses drive wheel spin, the first action taken by the control module is to: - answerN Apply the brake on the spinning drive wheel The right-front wheel setback is excessive on a MacPherson strut front suspension system. The most likely cause of this problem is: - answerN A binding right-upper strut mount. When the tread wear indicator is visible across the tread, the tire should be: - answerReplaced Technician A says that most front-wheel-drive cars have a frame that is separate from the body. Technician B says that most full size SUVs and trucks have a unitized body that combines the frame and body into one unit. Who is correct? - answerNEITHER Technician A says when the suspension height is normal, the valve orifices in a travel-sensitive strut provide more resistance to oil movement. Technician B says a travel-sensitive strut provides more resistance to oil movement when the speed of upward or downward wheel movement increases. Who is correct? - answerB During a road test on a front-wheel drive vehicle, it is determined that the vehicle pulls right after a right turn, and pulls left after a left turn. The most likely cause of this condition is: - answerA binding upper strut bearing Radial tire runout should be measured with a: - answerDial indicator Types of ball joint mounting in the lower control arm include all of these EXCEPT: - answerWelded When inspecting and servicing front wheel bearings on front-wheel-drive cars: - answer Some front wheel bearings mounted in the steering knuckle contain two tapered roller bearings with a split inner race. The perimeter-type frame is used when heavy load-carrying capacity is needed. - answerF Technician A says a tire pressure check is not required before a wheel alignment. Technician B says a front wheel bearing play should be checked before a wheel alignment. Who is correct? - answerB Technician A says some automatic air suspension systems have rotary height sensors. Technician B says rotary height sensors contain a Hall Effect element. Who is correct? - answerBOTH Which of these alignment angles assists in the return of the steering wheel to the straight-ahead position? - answerSAI Technician A says if a front wheel has positive camber, the camber line is at the true vertical centerline of the tire and wheel. Technician B says if the left-front wheel has excessive positive camber and the right-front wheel camber is correct, the steering pulls to the left. Who is correct? - answerB A worn flexible coupling may cause excessive steering wheel free play. - answerT A short-and-long-arm (SLA) front suspension system has a lower control arm that is longer than the upper control arm. - answerT
