Read the first 6 Steering and Suspension flashcards as text

  1. What is the correct method to test a ball joint for wear in a MacPherson strut suspension?

    Answer: Support the vehicle under the lower control arm to unload the spring and check for axial play

    In a MacPherson strut system, the ball joint is loaded by the spring; supporting the lower arm unloads the joint and allows proper axial play measurement.

  2. A vehicle's steering pulls to one side after hitting a pothole. What is the most likely cause?

    Answer: A bent steering arm or damaged control arm changing alignment angles

    A hard impact can bend steering and suspension components, altering alignment angles such as camber or toe, which will cause the vehicle to pull.

  3. Excessive free play in the steering wheel is found during a DFFT inspection. What is the maximum acceptable free play on most vehicles?

    Answer: Approximately 1–2 inches (25–50mm) before the front wheels begin to move

    Some free play is normal but excessive play—typically more than 1–2 inches at the rim—indicates worn steering components that compromise vehicle control.

  4. A vehicle's ride height is lower on the driver's side than the passenger's side. What is the most likely cause?

    Answer: A broken or sagged coil spring on the driver's side

    A broken or fatigued coil spring loses load-carrying capacity, causing the affected corner to sit lower than the opposite side.

  5. What is the correct sequence for a front wheel alignment procedure?

    Answer: Inspect and repair worn parts, set camber, then set toe last

    Alignment must begin with a full suspension inspection because setting angles on worn or damaged components is pointless; camber is set before toe because toe is the final adjustment.

  6. A customer complains of a vibration felt through the seat and floor at highway speed, not through the steering wheel. Which wheels are most likely out of balance?

    Answer: The rear wheels

    Steering wheel vibration originates from front wheel imbalance; vibration felt through the body structure and seat is transmitted from the rear wheels.
