A Vehicle Identification Number (VIN) reveals information about a vehicle’s manufacturer, model, year, engine, and where it was assembled. Which source would you use to decode a VIN?

• Service manual

• Vehicle’s owner’s manual

• Online VIN decoder or manufacturer database

• The vehicle’s dashboard sticker

When securing a vehicle on a two-post hydraulic lift, you should place the lift arms under which areas to ensure safe lifting?

• The bumper brackets

• The rocker panels

• The manufacturer’s recommended lift points

• The differential housing

Material Safety Data Sheets (MSDS) provide information about which of the following?

• The environmental impact of a repair

• The proper disposal of used tires

• The hazards, handling, and storage of chemicals

• The cost of replacement parts

Which tool would you use to measure the diameter of a brake rotor?

• Dial indicator

• Micrometer

• Torque wrench

• Feeler gauge

When using a torque wrench, you should always:

• Use it to loosen stuck bolts

• Store it at its highest torque setting

• Pull smoothly until the desired torque is reached

A vehicle with a pull to the right during braking may indicate which of the following suspension or steering issues?

• Bad tie rod end

• Misadjusted steering gear

• Uneven tire pressure or alignment

• Faulty fuel injectors

What is the purpose of a rack-and-pinion steering system?

• To convert rotational motion from the steering wheel into linear motion to turn the wheels

• To provide a reduction in braking distance

• To maintain engine speed

• To regulate fuel flow

When adjusting toe-in on a front-wheel alignment, you are adjusting:

• The angle between the top of the wheels and vertical

• The angle of the steering column

• The distance between the front edges of the tires compared to the rear edges

• The ride height of the vehicle

A clunking noise over bumps could be caused by worn:

• Spark plugs

• Sway bar links or bushings

• Fuel injectors

• Oxygen sensors

The caster angle affects which of the following aspects of steering?

• The ride height

• Straight-line stability and steering return

• Brake pad wear

• Fuel economy
