Which of these is a true statement about this procedure? - Answer-Care should be taken not to scratch the spring. Excessive effort is needed to turn the steering wheel on a vehicle with tilt wheel and rack and pinion steering. Any of these are likely causes EXCEPT: - Answer-worn rack and pinion mount bushings. Technician A says the tie rod sleeves may be rotated to adjust front wheel toe. Technician B says the tie rod sleeves may be rotated to center the steering wheel. Who is correct? - Answer-Both A and B A four-wheel drive (4WD) vehicle suffers excessive road shock at the steering wheel while driving on irregular road surfaces. Technician A says the power steering gear spool valve may be damaged. Technician B says the steering damper may be worn out. Who is correct? - Answer-B only A manual rack and pinion steering gear requires excessive steering effort. Technician A says the lower ball joints on the front suspension may have excessive play. Technician B says the rack bearing adjustment may be too tight. Who is correct? - Answer-B only A vehicle with non-independent front suspension has excessive tire squeal while cornering. The cause of this problem could be: - Answer-a bent steering arm. The steering pulls to the right while driving straight ahead on a vehicle with a short/long arm (SLA) front suspension and a leaf spring rear suspension. Any of these defects could be the cause of the problem EXCEPT: - Answer-excessive toe-in on the front wheels. Any of these statements about front wheel toe adjustments are true EXCEPT: - Answer-Rear toe is adjusted after front toe. The standard color for airbag wiring is: - Answer-yellow. Excessive steering effort on a manual steering-gear (non-rack and pinion type) may be caused by: - Answer-a tight sector lash adjustment. While using a spring compressor to remove a coil spring from a strut as shown in the figure, Technician A says the spring should be taped in the areas where the compressor contacts the spring if the compressor does not have protective inserts. Technician B says all of the spring tension must be removed from the upper strut mount before loosening the strut rod nut. Who is correct? - Answer-Both A and B On a rear suspension with two longitudinally mounted leaf springs, the left rear spring is sagged and the left rear chassis ride height is less than specified. This problem could result in: - Answer-a change in the front and rear alignment angles. The electronic suspension switch shown in the figure must be in the off position and disabled under any of these conditions EXCEPT while: - Answer-diagnosing the system with a scan tester. A vehicle with a front suspension cradle and strut-type suspension has a two-degree side-to-side camber difference. Which of these is most likely the cause? - Answer-Incorrectly positioned cradle Technician A says that some air shock absorbers can be pressurized with a shop air hose. Technician B says if a shock absorber slowly loses its air pressure, shock absorber replacement may be necessary. Who is correct? - Answer-Both A and B When installing variable rate coil springs on a rear suspension, any of these should be done EXCEPT: - Answer-The closed coils (coils closest together) should be at the bottom. With the steering column mounted in the vehicle and all linkages connected, a steering wheel has excessive freeplay. Technician A says the flexible coupling may be worn. Technician B says the steering gear mounting bolts may be loose. Who is correct? - Answer-Both A and B Technician A says if the center link has a ball-and-socket joint at one end that is loose, the whole center link must be replaced. Technician B says if one of the tapered holes is distorted, the whole center link must be replaced. Who is correct? - Answer-Both A and B Refer to the picture in the figure. What would be the proper method to add positive caster without changing camber? - Answer-Remove shims from the front shim pack and add an equal thickness of shims to the rear shim pack. While bleeding air from a power steering system, Technician A says if foaming is present in the reservoir after the bleeding process, the bleeding procedure should be repeated. Technician B says each time the steering wheel is rotated fully right or left, it should be held in this position for no more than two or three seconds. Who is correct? - Answer-Both A and B Caster may be adjusted by doing any of these EXCEPT: - Answer-tightening the torsion bar adjusting bolt. A customer complains about steering chatter while cornering with a MacPherson strut front suspension system. With the vehicle parked on the shop floor, the technician can feel a binding and releasing action on the left front spring as the steering wheel is turned. Technician A says the upper strut mount may be defective. Technician B says the lower ball joint may have excessive wear. Who is correct? - Answer-A only The turning radius on the right front wheel is not within specifications. The cause of this problem could be a: - Answer-bent steering arm. The tool shown in the figure is used to: - Answer-install a pressed-on power steering pump pulley. Some idler arms are adjustable. Technician A says they can be adjusted to allow the vehicle to turn in a tighter circle. Technician B says their adjustment can give the driver more road feel. Who is correct? - Answer-Neither A nor B The power steering rack and pinion gear is being removed on a vehicle equipped with an airbag. The first step the technician would perform is: - Answer-Disable the airbag system and lock the steering wheel in place. Any of these statements are true of sway bars EXCEPT: - Answer-The bar connects the lower control arms to the frame. Upon road-testing a front-wheel drive vehicle, the technician finds that the vehicle must be counter-steered in the opposite direction after every turn. Technician A says that this could be caused by a seized upper strut bearing. Technician B says that this condition is known as memory steer. Who is correct? - Answer-Both A and B A four-wheel alignment is being performed on a vehicle. Thrust angle needs to be corrected. Which adjustment is used to adjust the thrust angle? - Answer-Rear Toe Tapered roller front wheel bearings are being serviced on a rear-wheel drive vehicle, and there are metal flakes near the bearing rollers of the outer bearing only. Technician A says the outer bearing and race must be replaced and the other bearings should be cleaned, inspected, and packed with the proper grease. Technician B says all of the bearings on the front wheels must be replaced if one is bad. Who is correct? - Answer-A only Technician A says power rack and pinion gear assemblies do not have to be adjusted after repair. Technician B says manual rack and pinion gear assemblies must be adjusted after repair. Who is correct? - Answer-B only The cause of poor returnability on a vehicle equipped with manual rack and pinion steering gear could be: - Answer-insufficient caster A vehicle with power steering has increased steering effort in both directions. Technician A says that a bent center link could cause this problem. Technician B says that a seized idler arm could cause this problem. Who is correct? - Answer-B only Both front springs have been replaced on the vehicle. Which of these must also be performed? - Answer-align the vehicle An inspection is being performed on the rack and pinion steering system shown in the figure. Any of these should be checked EXCEPT the: - Answer-Pitman arm Technician A says lack of lubricant can seize the kingpin, causing hard steering. Technician B says to remove the outer tie rod end from the steering arm to check king pin pivot movement and ease of travel. Who is correct? - Answer-Both A and B While performing an alignment on a front-wheel drive vehicle, the technician notices that rear camber is out of specification and that camber is not adjustable on the vehicle. Which of these should the technician do first? - Answer-Check the rear cradle (subframe) alignment.
