Which of the following could be the cause. When the clutch is completely depressed. On a 4 wheel driver vehicle with drag link steering, after the alignment is complete and correct, The steering wheel is turned to the left when the vehicle is driving straight ahead. The fluod becomes thicker, allowing greater drag/grab in high need situations. Who is right? C. Both techs are right. Tech A is describing a proper adjustment procedure for tapered roller bearings. Technician A says to place a jack under the lower control arm to unload the ball joint. As a spring sags on a MacPherson strut, the top of the tire will lean inward, wearing the inner tire tread area first. A vehicle with variable assist power steering has a lack of power assist in both directions. The tire installer noticed that the vehicle has some play in the left side inner tie rod end and informs the alignment Tech. What is another name for the clutch release bearing?

The power steering pressure sensor informs the PCM/ECM of this high pressure, causing the PCM/ECM to in turn adjust the IAC valve to raise the engine idle speed. Learn vocabulary, terms, and more with flashcards, games, and other study tools. (2 names). The brakes are auto applied to the slipping wheel, sending the power to the wheel with traction. Tech B says that a faulty flow control valve could be the cause. The planetary gears are shifted/connected using what? However, always consult the vehicle service manual for the specific adjustment procedure. The main gear of the input shaft spins the countershaft at all times. D neither tech is right. 49. all of the following can cause incorrect vehicle ride height EXCEPT: D. Misadjusted torsion bars, sacked coil springs and broken leaf spring shackles would all cause a vehicles ride height to be too low. Tech A says that arranging shims to move the upper control arm toward the rear of the vehicle will increase caster. The pressure readings taken when the wheels are at the right and left stops are below specs. Caster will not cause tire wear, but excessive camber will cause wear to the inside of outside shoulders of a tire. The system should be flushed, and then air bled. 13. a vehicle with a manual rack and pinion steering gear has a shimmy. 62. Tech A says that reverse uses a 'counter' gear.

When testing ring gear backlash using tooth contact compound, how far should you rotate the ring gear? Tech B says that a static out of balance of the front wheels could be the cause. It supports the tip of the input shaft and allows the crankshaft and input shaft to spin at different speeds. Riveted joints are usually replaced with the bolt on replacements after the rivets are removed. What keeps the limited slip differential wheels locked in play while travelling forward? What are two more names for the counter shaft? A tire on an alloy wheel is being balanced. Whereas', rotating the wheel assembly on the mounting studs will have no effect on runout. The bearing in the center of a two piece drive shaft. Unless a DTC put the car into limp mode. How are electronic shifts made on a 4WD unit? The planetary gear is connected to a hi-lo range sleeve. All of the following are true statements regarding tapered wheel bearings EXCEPT: D. Tapered wheel bearings are mounted between the hub and fixed spindle and are commonly used on non drive axles. Connected to the clutch release fork on a sleeve on the input shaft. Who is right? The tester readings are normal when the tester shutoff valve is closed.

Topics for the A3 test include: Clutch Diagnosis and Repair Transmission Diagnosis and Repair Transaxle Diagnosis and Repair Drive Shaft/Half-Shaft Diagnosis and Repair (Front and Rear Wheel Drive) … What unit is engine vacuum usually measured in? Tech A is wrong because the wheel speed sensors in an indirect TPMS do not measure tire pressure. 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. (not fully disengaged). 24. Tire cupping is MOST likely caused by: D. Tire cupping or scalloping can result from worn shock absorbers, improperly balance wheels/ tires or loose/ defective tie rod ends. However, it must be removed when replacing the press fit type front wheel bearing. The stabilizer bar, also known as the sway bar, is used to control body roll, and a broken link would allow excessive body roll. The idler arm would not affect radial or axial tolerances. Pulley alignment should be checked as the pulley is installed; many pulleys are not installed until they bottom on a shoulder but rather just until they align. Tech B says that setback can be designed into a vehicle. When the clutch is disengaged and the engine is running. Tech B says that the intermediate shaft U joints could be binding. Study with actual ASE questions and answers - updated for 2020! This is because the direction of the twisting or torsion is not the same on the left and right sides. A customer is purchasing new front tires for her front- wheel driver vehicle. Tech B says the front coil springs could be sagged. 44.

Ball joints, tie rod ends, and pitman arms are always replaced. If the thrust line is to the left and the steering wheel is held straight, the vehicle will veer to the right. What is the purpose of the planetary assembly? The output shaft is only engaged with the countershaft when a shift sleeve is locking the driven gear to the countershaft. During a road test, a customer's car nose dives badly during braking, and also has a vibration and seems to "float" at highway speeds. Tech A says that a power steering pump pulley should be pressed onto the pump shaft until it stops, to ensure proper pulley alignment. The gears are in constant mesh, but spin freely from the countershaft until enagaged. However, some vehicles have an intermediate shaft connecting the steering column with the gear.
