Technician A says maintenance-free batteries have a built-in hydrometer can give you an indication of the battery's overall condition. Technician B says since a maintenance-free battery is sealed, it should be checked using a test light. Who is right?

Technician A says that lubricant can be used to help seat a tire on a wheel rim. Technician B says that if necessary, it is OK to exceed the maximum tire pressure rating to seat the bead, as long as the pressure is reduced immediately afterward. Who is right?

Technician A says that all vehicles with strut-type front suspension require that the strut is removed to replace the front coil springs. Technician B says that the coil spring should be compressed before removal from an SLA front suspension. Who is right?

Which of the following causes for ball joint replacement could also require steering knuckle replacement?

All of the following are true statements regarding tapered wheel bearings EXCEPT:

Technician A says an indirect measurement Tire Pressure Monitoring System (TPMS) uses wheel speed sensors to measure tire pressure. Technician B says a direct measurement TPMS uses tire pressure sensor to measure tire pressure. Who is right?

Tire cupping is MOST likely caused by which of the following?

Technician A says a noisy alternator could be caused by a bad diode. Technician B says a noisy alternator could be caused by a worn bearing. Who is right?

Which setting on a digital multimeter is used to check resistance?

Voltage drop tests are used to locate:

When testing computer-controlled systems, a Digital Multimeter (DMM) should be used with an input impedance of at least:
