ASE A4 practice test Questions And Answers Verified 100% Correct. Too much caster on the left front wheel will cause the __________ A. vehicle to drift to the left B. Left tire to wear on the outside edge C. vehicle to drift to the right D. left tire to wear on the inside edge. - ANSWER C. A vehicle will tend to steer or drift to the side with the least amount of caster. Caster will not cause tire wear, but excessive camber will cause wear to the inside of outside shoulders of a tire. A pressure test is being performed on a car with power steering. The pressure readings taken when the wheels are at the right and left stops are below specs. The tester readings are normal when the tester shutoff valve is closed. tech A says that these readings could be caused by a bad steering gear. tech B says that a bad pump could cause these readings. Who is right? A. Tech A Only B. Tech B Only C. Both A and B D. neither - ANSWER A. A bad steering gear would cause the readings to be low when the steering is at the right and left stops, but the readings would be normal with the tester shutoff valve closed. a vehicle with a manual rack and pinion steering gear has a shimmy. Tech A says that worn rack to frame mounting bushings could be the cause. tech B says that loose inner or outer tie rod ends (sockets) could be the cause. Who is right? - ANSWER C. Both Techs are right. Steering play or looseness may occur if the rack to frame mounting bushings are worn, or if the inner or outer tie rod ends are loose. both of these conditions can result in a shimmy. The ball joints on a Macpherson strut- type suspension are being replaced. Tech A says that coil spring compressor should be installed before separating the control arm and the spindle. Tech B says that the wheel alignment should be checked after the ball joints have been replaced. Who is right? A. tech A Only B. Tech B Only C. Both A and B D. Neither - ANSWER B. The wheel alignment should be checked after the ball joint (or any suspension part) is replaced. It is not necessary to install a coil spring compressor prior to separating the control arm and the spindle because the MacPhearson strut assembly contains a spring. However, a spring compressor should be used if the strut is being disassembled. . The rear thrust line reads to the left (drivers side) while the vehicle is at normal ride height. If the wheels were pointing straight ahead, which direction would the vehicle tend to wander A. Veer to the left B. Veer to the right C. Wander to both left and right D. No change occurs - ANSWER B. If the thrust line is to the left and the steering wheel is held straight, the vehicle will veer to the right. This happens because the rear wheels will travel towards the left, Which will force the front of the vehicle to the right. Tech A says that the bearing preload must be set when overhauling a manual steering gear. Tech B says that the sector lash must be set when overhauling a manual steering gear. Who is right? A. Tech A only B. Tech B Only C. Both techs D. Neither A or B - ANSWER C. Both techs are right. Both bearing preload and sector lash adjustments are necessary after an overhaul. Correct sector lash prevents gear binding and excessive steering wheel free play. Correct preload prevents worm end play and loose steering feel. A vehicle with power steering has assist in only one direction. Tech A says that oil leaking past a worm shaft seal ring could be the cause Tech B says a broken ring on the worm piston could be the cause. Who is right? A. Tech A B. Tech B C. Both A and B D. Neither A or B - ANSWER C. Both techs are right. An oil leak past the worm shaft oil sealing ring or a broken ring on the worm piston could cause the power steering to only have assist in one direction. A vehicle with power steering has no assist in either direction. Tech A says that a loose power steering belt could be the cause. Tech B says that a faulty flow control valve could be the cause. Who is right? A. Tech A only B. Tech B only C. Both A and B D. Neither A or B - ANSWER C. Both techs are right. A faulty control valve will reduce the fluid pressure and cause an increase in steering effort. A loose power steering pump drive belt will create a similar condition. A customer complains of excessive body roll. Which of the following is the MOST likely cause. A. broken stabilizer bar link B. worn ball joint C. weak coil spring D. leaking shock absorber - ANSWER A. The stabilizer bar, also known as the sway bar, is used to control body roll, and a broken link would allow excessive body roll. Tech A says that the wheel bearings can be adjusted by tightening the nut while turning the hub , and then backing off the nut part of a turn. Tech B says the end play in the bearings can be checked using a dial indicator. Who is right? A. Tech A only B. Tech B only C. Both A and B D. Neither tech - ANSWER C. Both techs are right. Tech A is describing a proper adjustment procedure for tapered roller bearings. tech B is also right because, after the adjustment, there should be 0.001-0.007 Inches end play. However, always consult the vehicle service manual for the specific adjustment procedure. Tech A says that the ride height of a vehicle is always adjustable. Tech B says that the ride height of a vehicle can only be adjusted on certain models. Who is right? A. Tech A only B. Tech B only C. Both A and B D Neither tech - ANSWER B. Ride height is only adjustable on some models. On most models, parts replacement is the only way to correct ride height. Tech A says that caster is not a tire wearing angle. Tech B says that toe-in or Toeout will cause tire wear. Who is right? A. Tech A only B. Tech B only C. Both A and B D. Neither Techs - ANSWER C. Both techs are right. Caster will have an effect on steering and handling, but will not cause tire wear. However, if a suspension system has too much toe in or toe out, tire wear will result. 23. Tech A says that if steering axis inclination is out of spec, A bent control arm may be the cause. Tech B says that if steering axis inclination is out of spec, the spindle can be shimmed to correct the problem. Whos is right? A. Tech A only B. Tech B only C. Both A and B D. Neither A or B - ANSWER A. A bent control arm would cause the angle of pivot points to change and subsequently change the steering axis inclination angle. Tech B is incorrect because shimming a spindle is not a recommended procedure and it would affect eh included angle, not the steering axis inclination angle. 24. Tire cupping is MOST likely caused by: A. Worn shock absorbers B. wheel imbalance C. Loose tie-rod ends D. All of the above - ANSWER D. Tire cupping or scalloping can result from worn shock absorbers, improperly balance wheels/ tires or loose/ defective tie rod ends. 25. Which of the following is most likely to be lubricated and sealed by the manufacturer? A. Needle bearings B. tapered roller bearings C. plain bearings. D. Ball bearings - ANSWER D. Most ball bearings are factory lubricated and sealed for Life. 26. Excessive steering wheel play is felt in the steering wheel on a manual steering system. Tech A says that a worn idler arm could be the cause. Tech B says that a misadjusted mesh preload may be the cause. Who is right? A. Tech A only B. Tech B only C. Both A and B D. Neither Tech - ANSWER C. Both techs are right. Excessive steering wheel lay may result from a worn idler arm and/or maladjusted mesh preload. 27. A vehicle suspension system is being checked for radial and axial tolerances. Tech A says that ball joints should be checked. Tech B says that The idler arm should be checked. Who is Right? A. Tech A only B. Tech B only C. Both A and B D. Neither A or B - ANSWER A. When checking the radial and axial tolerances, an inspection of the ball joints should be performed. The idler arm would not affect radial or axial tolerances. 28. A vehicle has a noise coming from the power steering pump. Tech A says that a loose belt could be the cause. Tech B says that air in the system could be the cause. Who is right? A. Tech A only B. Tech B only C. Both A and B D. Neither A or B - ANSWER C. Both Techs are right. A loose power steering pump belt and air could both cause power steering pump noise. 29. All of these are types of power steering pumps, Except A. Vane B. Roller C. Slipper D. Crescent - ANSWER D. A power steering pump can be a roller, slipper or vane type. 30. all alignment measurements on a vehicle are within spec, except SAI and Toe-out on turns. Tech A says that these alignments angles are not adjustable, so there is nothing more to do. Tech B says neither of these angles can cause tire wear. Who is right? A. Tech A only B. Tech B only C. Both tech A and B D. Neither A or B - ANSWER D neither tech is right. While it is true that SAI and toe out on turns cannot be adjusted, they indicate that some component is bent and must be replaced. Incorrect SAI will cause changes in camber while turning and incorrect toe out will abrade tire rubber. 31. A car is raised on a lift with the wheels pointed straight ahead and when the engine is started, the wheels slowly turn to the right. Tech A says that a binding upper bearing
