AUT-128 final exam Completely Solved Correct!!

Technician A says the clutch allows the engine to idle while the vehicle is stopped. Technician B says the clutch is needed for gear shifting. Who is correct? - ANSWER both a and b The two driving members [inputs] of the clutch assembly are the flywheel and ______. - ANSWER pressure plate The CV joints nearest the transaxle are called the ______ joints - ANSWER both "inner" and "inboard" Technician A says the front of the transmission input shaft may be supported by a pilot bearing. Technician B says on some transaxles the input shaft is not supported by a pilot bearing. Who is correct? - ANSWER both a and b An engine support fixture is used to hold the engine in place while removing a ______. - ANSWER FWD transaxle Technician A says part-time 4WD vehicles do not have an interaxle differential. Technician B says part-time 4WD vehicles do not have a transfer case. Who is correct? - ANSWER a only Insufficient clutch pedal clearance results in ______. - ANSWER premature release bearing failure The Haldex clutch in the all-wheel drive automatic transaxle takes the place of the ______ - ANSWER interaxle differential When the clutch pedal is released on a hydraulic clutch linkage, the ______ - ANSWER master cylinder piston is released by the piston return spring Technician A checks the flywheel for runout [warpage] using a dial indicator. Technician B uses a straightedge to check the pressure plate for warpage. Who is correct? - ANSWER both a and b A rough growling noise occurs when the vehicle is moving and the transmission is in forward or reverse gears. The noise is not heard when the transmission is in neutral. Technician A says the output or main shaft bearings may be faulty. Technician B says the pilot bearing may be faulty. Who is correct? - ANSWER a only When fourth gear is selected on a five-speed manual transmission, the synchronizer couples the ______. - ANSWER clutch [input] gear to the main shaft Viscous clutches are being discussed. Technician A says if the clutch malfunctions, it must be replaced. Technician B says viscous clutch fluid must be checked periodically. Who is correct - ANSWER a only Technician A checks the condition of blocking rings by measuring the clearance between the blocking ring and the face of the gear. Technician B visually inspects the blocking ring for worn clutch teeth and smooth internal surfaces. Who is correct? - ANSWER both a and b The double-offset joint is typically used in applications that require ______. - ANSWER higher operating angles and greater plunge depth A FWD vehicle that makes a clunking noise when the automatic transmission is shifted into gear is being diagnosed. Technician A says the problem could be excessive play in an inner or outer CV joint. Technician B says the noise could be produced by excessive backlash in the differential gears and transmission. Who is correct? - ANSWER both a and b Technician A says the differential allows torque to be transmitted to the driving axles at different speeds when the vehicle is turning a corner. Technician B says the gear ratio of the drive axle's ring and pinion gears provide a gear reduction and torque multiplication. Who is correct ? - ANSWER both a and b Technician A checks the engine and transmission mounts by running the engine at 1,500 rpm and with the park brake on lightly applying the clutch, while an assistant observers the movement of the engine and transmission. Technician B checks the mounts by applying 100 ft./lbs. of torque to the drive shaft with a torque wrench while measuring the movem
