ASE A4 Steering Suspension Practice Test

36. A vehicle has a steady pull to the left. All of these will cause this condition EXCEPT:

  • A. The caster angle.
  • B. Low tire pressure.
  • C. The camber angle.
  • D. Steering U-joint coupling.

36.

Answer A is wrong. An incorrect caster angle will cause a vehicle to pull.

Answer B is wrong. Low tire pressure will cause a vehicle pull.

Answer C is wrong. An incorrect camber angle will cause a vehicle to pull.

Answer D is correct. A loose steering universal joint will cause play in the steering wheel.

37. Technician A says a vehicle will pull to the side with the most positive camber. Technician B says that too much negative camber will result in excessive wear on the inside tread of the tire. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

37.

Answer A is wrong. Both technicians are correct. A vehicle will pull to the side with the most positive camber.

Answer B is wrong. Negative camber results in tire wear on the inside tread of the tire. Positive camber results in tire wear on the outside tread of the tire.

Answer C is correct. Excessive camber will cause both tire wear and pull.

Answer D is wrong. Both technicians are correct.

38. Two technicians are discussing inner and outer tie rods. Technician A says to turn the outer tie rod end to adjust the toe. Technician B says loose inner tie rod ends will cause a tire to feather. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

38.

Answer A is wrong. A sleeve is used to adjust toe on many gearbox/parallelogram steering systems found on trucks and rear wheel cars. It's important not to damage this sleeve, special tools are produced. Typically inner tie rods are turned to lengthen and shorten the tie rods length on rack and pinion systems.

Answer B is correct. Loose inner tie rod ends cause a vehicle to shimmy and feathered tire wear. Using an inexpensive special tool should greatly reduce labor. The inner tie rod end on a rack and pinion steering system is rotated to make toe adjustments.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

39. The rear tires on a vehicle with independent rear suspension are worn on the inside tread. Which of the following is MOST likely the cause of this condition?

  • A. The toe.
  • B. Underinflated tires.
  • C. The caster.
  • D. None of the above.

39.

Answer A is correct. Both front and rear toe are tire wearing angles. Out of specification toe on the rear of a vehicle will also cause an out of specification thrust angle, vehicle pull, and an off center steering wheel.

Answer B is wrong. An underinflated tire will wear on both outside edges of the tire.

Answer C is wrong. Caster is a front wheel angle, it supports stability and steering wheel return to center. Out of specification camber on a rear wheel will cause tire wear on one side of the tire.

Answer D is wrong. Out of specification rear toe will cause excessive tire wear.

40. Technician A says SAI or Steering Angle Inclination is adjusted by changing the caster angle. Technician B says camber adjustments are included in the Included Angle. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

40.

Answer A is wrong. If the SAI is out of specifications, a damaged or bent part is most likely the cause. Always do a complete inspection of the vehicle's suspension.

Answer B is correct. Camber is part of the included angle.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
