A4 Steering and Suspension Quiz

1. Technician A says that loose power steering rack bushings result in vehicle wander. Technician B says worn rack bushings cause changes in toe. Who is correct?
2. Two technicians are discussing the toe setting of a front wheel drive vehicle with four wheel independent suspension. The right rear wheel is 1.5 degrees toe-in from specifications. Technician A says to set the front toe on this vehicle before correcting the rear. Technician B says the right rear wheels toe setting is 1.5 degrees positive (+). Who is correct?
3. There is noticeable wear on the left front tire of a rear wheel drive vehicle. The technician suspects the camber angle is out of specification. All these characteristics of camber are true EXCEPT:
4. Technician A says a vehicle with torsion bar suspension can be adjusted to repair ride height. Technician B says on some vehicles, torsion bars are used in place of coil springs. Who is correct?
5. A vehicle feels bouncy and is oscillating at highway speeds. The vehicle's shock absorbers may be faulty. Technician A says it is acceptable for a slight film to appear on the shock absorber's shaft. Technician B says a small drip of oil appearing from the shock absorber's chamber is acceptable. Who is correct?
6. A vehicle with a power rack and pinion steering system is binding during turns. Which of following is LEAST likely to cause this condition.
7. Two technicians are discussing excessive wear on the inside tread of a tire. Technician A says an out of specification caster angle will cause this type of wear. Technician B says an out of specification camber angle will cause this type of wear. Who is correct?
8. After installing a power steering gear, the vehicle's air bag light is illuminated. Technician A says the vehicle's wheel alignment needs to be adjusted to repair this light. Technician B says the clockspring has been damaged. Who is correct?
9. A vehicle pulls to the right and makes a clunking sound when the brakes are applied. During an alignment check the technician notices excessive negative caster on the right front wheel. Technician A says this is most likely caused by a seized brake caliper. Technician B says this is most likely caused by worn or missing strut rod bushings. Who is correct?

10. The vehicle in the alignment chart pulls to the right. Technician A says this is because a vehicle will pull to the side with the most camber. Technician B says this is because the vehicle's caster angle is out of specifications. Who is correct?

11. During the visual inspection of a light truck, the technician notices the left rear leaf spring has a broken center bolt. Technician A says this will affect the vehicle's thrust angle. Technician B says an incorrect thrust angle will affect the centering of the steering wheel. Who is correct?
12. A technician is unable to balance a tire and has added weights in several places around the rim. Technician A says to continue adding weights up to 10 ounces. Technician B says to dismount the tire from the rim and inspect the inside for liquid or debris. Who is correct?
13. The left front tire of a vehicle is feathered across its tread. What is the MOST likely cause of this condition?
14. Technician A says that a variable rate coil spring has varying spaces between the coils. Technician B says if a vehicle has a noticeable difference in height between sides, it may have a weak strut insert. Who is correct?
15. Technician A says the power steering pressure switch sends a signal to the PCM to increase idle speed while parking. Technician B says variable assist steering provides maximum pressure during high speed operation. Who is correct?

16. The vehicle in the alignment chart above has excessive shimmy above 45 mph. The MOST likely cause of this condition is:

17. A vehicle with a power rack and pinion steering system doesn't return to center after completing a turn. Technician A says an incorrect caster angle will cause this condition. Technician B says a binding lower ball joint would have no affect on steering wheel return to center. Who is correct?
18. The LEAST likely to result in memory steer is a binding:
19. Two technicians are discussing struts on a front wheel drive vehicle. Technician A says some struts have a camber lobe adjustment. Technician B says a worn strut tower will make excessive noise when going over bumps. Who is correct?
20. Technician A says a worn idler arm has no affect on a vehicle's total toe setting. Technician B says the center link is used in parallelogram linkage systems. Who is correct?
