  1. What does it mean when your steering wheel vibrates at highway speeds?

    Answer: The tires are out of balance or the wheels are misaligned

    Steering wheel vibration at highway speeds typically indicates tire imbalance or wheel misalignment, both of which cause uneven tire wear and poor handling.

  2. What is the purpose of the timing belt or chain in an engine?

    Answer: To synchronize the crankshaft and camshaft rotation

    The timing belt or chain synchronizes the crankshaft and camshaft so that engine valves open and close at the correct time relative to piston position.

  3. Why should you avoid 'riding the clutch' in a manual transmission vehicle?

    Answer: It causes premature clutch wear by creating friction

    Riding the clutch keeps the clutch disc partially engaged, creating constant friction that accelerates wear and shortens clutch life significantly.

  4. When is it appropriate to use your vehicle's four-wheel drive (4WD) high range?

    Answer: On slippery roads at speeds up to 55 mph

    4WD high range is designed for slippery road conditions at moderate speeds, providing extra traction without the gear reduction of 4WD low.

  5. What does a clicking noise when turning indicate in a front-wheel-drive vehicle?

    Answer: A worn CV (constant velocity) joint

    A clicking noise while turning in a FWD vehicle typically indicates a worn or damaged CV joint, which transfers power to the wheels through the steering angle.

  6. What is the correct way to check engine oil level?

    Answer: Check with engine off, on level ground, after it has sat for a few minutes

    Engine oil should be checked with the engine off and the vehicle on level ground, allowing oil to drain back into the pan for an accurate dipstick reading.

  7. What is 'hydroplaning' and which vehicle factor most reduces its risk?

    Answer: Tires riding on a water film; prevented by adequate tread depth

    Hydroplaning occurs when tires ride on a film of water rather than the road surface; adequate tread depth channels water away to maintain road contact.
