  1. A clicking noise from the front of a FWD vehicle during sharp turns usually means:

    Answer: Worn outer CV joint

    A worn outer CV joint clicks during turns under load.

  2. An open circuit measured with an ohmmeter (power off) will read:

    Answer: Infinite resistance (OL)

    An open circuit has no continuity, so resistance reads infinite or OL.

  3. Excessive backlash in a differential ring and pinion will cause:

    Answer: A clunk on acceleration/deceleration

    Too much ring-and-pinion backlash produces a clunk when load reverses.

  4. A glow plug system is primarily found on which engine type?

    Answer: Diesel

    Glow plugs preheat the combustion chamber to aid cold starting of diesel engines.

  5. Which test best confirms a slipping serpentine belt causing low alternator output?

    Answer: Inspect belt tension and check charging voltage at RPM

    A loose or glazed belt reduces alternator drive, so checking tension and charging output confirms it.

  6. A growling or rumbling that increases with vehicle speed regardless of steering input points to:

    Answer: A failing wheel bearing

    Speed-dependent rumble that ignores steering is classic wheel-bearing failure.

  7. The correct way to fasten a critical component to spec is to use a:

    Answer: Torque wrench set to the manufacturer value

    A calibrated torque wrench ensures fasteners reach the specified clamping force.
