26. A vehicle with a power rack and pinion steering system is binding during turns. Which of the following is LEAST likely to cause this condition?
27. 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?
28. 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?
29. The left front wheel is sitting back 1 1/8 inches further than the other. Technician A says this is an acceptable setback and designed into the vehicle to compensate for crowned roads. Technician B says front wheel setback will cause a vehicle to drift towards the side with the least wheel setback. Who is correct?
32. A front wheel drive vehicle is pulling to the left. Loose engine cradle bolts are noticed during the initial inspection. Technician A says loose engine cradle bolts will cause a vibration, but have no affect on the vehicle's steering system. Technician B says if the engine cradle is not centered before fastening the bolts, the wheel alignment angles will be affected. Who is correct?
33. Two technicians are discussing an electronic air suspension system. Technician A says the suspension switch must be turned off before lifting the vehicle. Technician B says to use soapy water to visually inspect this system for leaks. Who is correct?
34. Loose tie rod ends are discovered during the initial inspection of a vehicle's steering linkage. Technician A says loose tie rods will cause a clunking or popping noise while turning. Technician B says loose tie rods will result in constant steering correction and vehicle wander. Who is correct?
35. Technician A says a directional tire must be kept on the same side of the vehicle during a tire rotation. Technician B says tire inflation pressure is considered cold as long as the vehicle has been driven less than ten miles. Who is correct?
36. A vehicle has a steady pull to the left. All of these will cause this condition EXCEPT:
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?
38. Two technicians are discussing the inner and outer tie rods on a rack and pinion steering system. Technician A says to turn the outer tie rod end to adjust the toe. Technician B says a loose inner tie rod end will result in a feathered tire tread. Who is correct?

44. 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?

48. A vehicle’s steering wheel is binding while turning in both directions. Technician A says the steering shaft universal joint is most likely causing this bind. Technician B says the intermediate shaft may need replacement. Who is correct?
49. There’s a squeak in the steering column when the steering wheel is turned in either direction. All of the following components will result in a noisy steering column EXCEPT the:
50. Technician A says loose tie rod ends result in steering wander. Technician B says to rock the tire back and forth at the three and nine o’clock positions to check for tie rod looseness. Who is correct?
52. A vehicle's steering wheel does not return to center after completing a turn. Which of the following is MOST likely causing this condition?
53. A technician is replacing weak coil springs on a light truck with coil spring suspension. Which of the following is not used to support a solid axle with this type of suspension?
