50. Which of these adjustments is made to compensate for road crown? a. Adding slightly more negative caster on the left side b. Adding slightly more positive caster on the left side c. Adding slightly more negative toe on the left side d. Adding slightly more negative caster on the right side 51. Technician A says comparing the SAI, included, and camber angles can help identify damaged or worn components. Technician B says if the toe-out-on-turns (turning angle) is incorrect, the tie-rods, steering arm, or steering knuckle will be damaged and need to be replaced. Who is correct? a. A only b. B only c. both A and B d. neither A nor B 52. How would a vehicle handle if it had a negative caster angle? a. The tires would squeal when turning. b. Heavy road shock would be felt in the steering. c. High steering effort d. Unstable at higher speeds 53. Which of the following statements is false? a. SAI refers to steering axis inclination. b. Unequal side-to-side SAI will not cause a pull while driving. c. SAI causes the steering system return to the straight- ahead position after a turn. d. SAI angles out of specifications indicate damaged or worn steering or suspension components. 54. When the right front wheel is turned 20 degrees to the left the left front wheel moves only 18 degrees. What could be the problem? a. steering arm c. excessive setback on the left side b. bent pitman arm d. power steering pump
