ASE A4 Steering Suspension Practice Test

11. Technician A says two different size tires on the rear of a vehicle will illuminate the amber ABS light. Technician B says the 60 in P225/60R16 89H indicates the tire's section width. Who is correct?

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

11.

Answer A is correct. Two different size tires or wheels on the rear of an ABS equipped vehicle will have a negative affect on the system and illuminate the ABS light. Because of the difference in tire size, the wheels will spin at different speeds.

Answer B is wrong. The three digits following the P, (225) indicate the tire's section width.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

12. A front wheel drive passenger vehicle's steering wheel does not return to the center after completing a turn. Which of the following is causing this condition?

  • A. The caster angle.
  • B. A binding ball joint.
  • C. A binding tie rod end.
  • D. All of the above.

12.

Answer A is wrong. Cars and light trucks typically have a positive caster setting; this helps the steering wheel return to center.

Answer B is wrong. A binding ball joint will affect the steering wheel's ability to return to the center. It will also result in a clunking noise while turning the wheel.

Answer C is wrong. Check the tie rod ends, idler arm, and other steering linkages for binding.

Answer D is correct. If something is binding in the column, linkage, or gearbox, the steering wheel return to the center will be affected. Steering wheel returnability is dependent on the caster angle, and most vehicles incorporate positive caster (~ 6° ) into both front wheels.

13. A vehicle's right front wheel is making a growling noise that increases with vehicle speed. All of these will result in this condition EXCEPT:

  • A. Excessive caster.
  • B. Cupped tire tread.
  • C. Worn struts.
  • D. Worn wheel bearing.

13.

Answer A is correct. Caster is viewed from the side of the vehicle. It is the forward or rearward tilt of the steering axis. It is not considered a tire wearing angle.

Answer B is wrong. A cupped tire will make a growling noise as it travels down the road.

Answer C is wrong. Worn struts result in cupped or scalloped tires. Cupped tires cause a growling noise while traveling down the road.

Answer D is wrong. A faulty wheel bearing will cause a growl that increases with vehicle speed.

14. Two technicians are performing a power steering pressure test. Technician A says a restriction in the high pressure line results in higher than normal test results. Technician B says if the pressure increases when the shutoff valve is closed, there's a problem with the power steering pump. Who is correct?

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

14.

Answer A is correct. A restriction in the high pressure line will result in higher than normal test results.

Answer B is wrong. If the pressure increases, then the pump is creating pressure as it should.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

15. Two technicians are discussing a recirculating ball steering gear. Technician A says to measure worm bearing preload with a foot pound torque wrench. Technician B says an under adjusted sector shaft will result in excessive steering wheel free play. Who is correct?

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

15.

Answer A is wrong. Technician B is correct. Measure worm bearing preload with an inch pound torque wrench. Worm bearing preload and sector gear mesh are both adjustments made to recirculating ball steering gears.

Answer B is correct. This adjustment will affect steering wheel free play. The steering wheel will feel loose and sloppy if under-adjusted or if the gearbox or mounting bolts are loose.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
