Steering Systems Diagnosis and Repair

1.	Technician A says if the steering column input shaft is not aligned correctly there would be noise. Technician B says if the lubricant level is low in a linkage-assist type power steering column, there will be a noise when turning the steering wheel. Who is right?

		c. Both A and B
		d. Neither A nor B
Both technicians are correct. Incorrect answer. Please choose another answer.

Steering Systems Diagnosis and Repair

2.	A sport utility vehicle has high steering effort. Technician A says this could be caused by a sheared shift tube. Technician B says the steering column assembly is misaligned. Who is right?
		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
Technician B is correct because column misalignment causes high steering effort due to binding. A sheared tube will result in loss of steering ability. Incorrect answer. Please choose another answer.

Steering Systems Diagnosis and Repair

3.	Technician A says whenever working on the steering column, consult the on-line service information for the recommended airbag disabling procedure. Technician B says the u-joint or flexible coupling must be removed before the steering wheel can be removed. Who is right?
		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
Technician A is correct because you must use the OEM information because, if done incorrectly, it can result in air bag deployment and possible personal injury. Incorrect answer. Please choose another answer.

Steering Systems Diagnosis and Repair

4.	This question has the word LEAST. For this question, look for the choice that would LEAST LIKELY cause the described situation. Read the entire question carefully before choosing your answer. While driving a vehicle at 40 miles per hour there is a vibration in the steering wheel. Which of the following is the LEAST likely cause?
		a. Improper wheel balance
		b. Worn control arm bushings
		c. Bent wheel
		d. Shifted belt inside tire
Of the answer options, a worn control arm bushings is the least likely to cause vehicle vibration as described. Incorrect answer. Please choose another answer.

Steering Systems Diagnosis and Repair

5.	On an integral power steering gear, which of the following indicates excessive play between the rack piston and sector?
		a. Lost motion within steering gear
		b. Steering wheel vibration
		c. Hard steering condition when cold
		d. Hard steering condition when hot
A lost motion is caused by excessive play between the rack piston and sector Incorrect answer. Please choose another answer.

Suspension Systems Diagnosis and Repair

6.	Two technicians are discussing vehicle ride height. Technician A says when the vehicle ride height is too low the vehicle could pull to that side. Technician B says ride height does not affect front camber. Who is right?
		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
Technician A is correct because if one side is different in height it will cause a pull. Ride height does affect camber and must be corrected before any alignment adjustments. Incorrect answer. Please choose another answer.

Suspension Systems Diagnosis and Repair

7.	Two technicians are discussing the ride height measuring procedure. Technician A says bent components can cause incorrect ride height. Technician B says for proper measurement of the ride height, the vehicle must have a full tank of fuel. Who is right?
		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
Both Technicians are correct. Incorrect answer. Please choose another answer.

Suspension Systems Diagnosis and Repair

8.	When replacing a lower control arm bushings on a short arm long arm (SLA) suspension, the replacement should be:
		a. Tightened and torqued in a vise
		b. Tightened using the torque turn method
		c. Torqued with vehicle weight on suspension
		d. Torqued with control arm resting on frame
The suspension needs to be loaded when bushing retention bolts are tightened. The other choices are wrong. Incorrect answer. Please choose another answer.

Suspension Systems Diagnosis and Repair

9.	Which of the following conditions is likely to indicate a worn control arm bushing?
		a. Ball joint play
		b. Front suspension sag
		c. Rubber bushing is cracked
		d. Fails the bounce test
Cracking of the rubber bushing is an indicator of wear. Incorrect answer. Please choose another answer.

Suspension Systems Diagnosis and Repair

10.	Two technicians are discussing the replacement of a rebound or jounce bumper. Technician A says if a vehicle fails the jounce test the cause is a defective jounce bumper. Technician B says you need to remove the lower ball joint to replace the jounce bumper on an SLA (short arm long arm) suspension. Who is right?
		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
Both technicians are correct. Incorrect answer. Please choose another answer.

11.	When a shock absorber is to be considered for replacement due to a fluid leak, which of the following applies?
		a. It must show an oil film on the outside.
		b. It fails the bounce test.
		c. It should be weighed to determine if it is low on oil.
		d. It should be removed and inverted to see if it drips oil.
A shock that fails the bounce test is defective regardless of leakage. Incorrect answer. Please choose another answer.

12.	This question has the word EXCEPT. For this question, look for the choice that could NOT meet the described situation. Read the entire question carefully before choosing your answer. All of the following statements about a conventional shock absorber are true, EXCEPT:
		a. A slight oil leakage film is considered normal.
		b. A worn or leaking shock will not cause a vehicle to lean.
		c. Purge the air from new shocks before installing.
		d. Oil leakage will cause the vehicle to fail a bounce test.
A shock that fails the bounce test is defective regardless of leakage. Incorrect answer. Please choose another answer.

		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
Technician B is correct because procedures may vary and it is best to follow OEM procedures. Technician A is wrong because the vehicle must be unloaded to make the adjustment on SLA suspensions. Incorrect answer. Please choose another answer.

		a. A only
		b. B only
		c. Both A and B
		d. Neither A nor B
B is correct because the vehicle thrust angle is determined by the rear toe adjustment. Rear camber adjustments are not used by many manufacturers. Incorrect answer. Please choose another answer.
