ASE A4

A vehicle with rack and pinion steering has a shimmy. Technician A says that worn rack-to-frame mounting bushings could be the cause. Technician B says that a binding steering shaft U-joint could be the cause. Who is right? A only B only Both A and B Neither A nor B

A only

While traveling at highway speed, a vibration is felt in the steering wheel and the front end of the vehicle vibrates up and down. Technician A says that a leaking power steering rack could be the cause. Technician B says that static out-of-balance of the front tires could be the cause. Who is right? A only B only Both A and B Neither A nor B

B only

A vehicle wanders while being driven on level roads. Technician A says that too much negative camber could be the cause. Technician B says that too much positive caster could be the cause. Who is right? A only B only Both A and B Neither A nor B

Neither A nor B

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

a. A only 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.

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

a. A only 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.

The steering wheel sensor is typically located at which of the following locations? a. Base of the steering column b. Under the air bag c. On top of the rack and pinion gear d. Inside the rack and pinion gear

a. Base of the steering column

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 within steering gear A lost motion is caused by excessive play between the rack piston and sector

Technician A says the rear camber determines the thrust angle. Technician B says the rear toe angle determines the thrust angle. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B

b. B only

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 check b. B only c. Both A and B d. Neither A nor B

b. B only Technician B is correct because column misalignment causes high steering effort due to binding. A sheared tube will result in loss of steering ability.

Two technicians are discussing wheel bearing adjustment on an SLA (short arm long arm) suspension. Technician A says you adjust the front wheel bearings with the vehicle on the ground. Technician B says to use factory procedures when adjusting front wheel bearings. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B

b. B only 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.

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. check 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.

b. It fails the bounce test. A shock that fails the bounce test is defective regardless of leakage.

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

b. Worn control arm bushings Of the answer options, a worn control arm bushings is the least likely to cause vehicle vibration as described.

Two technicians are describing camber. Technician A says camber affects tire wear. Technician B says rebound causes a slight negative change in camber on a SLA (Short/Long arm) suspension. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B

c. Both A and B

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

c. Both A and B

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 check c. Both A and B d. Neither A nor B

c. Both A and B Both Technicians are correct.

A driver comes in with a wandering concern on an SLA (short arm long arm) suspension. Technician A says a worn relay rod ball socket may be the cause. Technician B says the tie rod adjusting limit may be out of specification. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B

c. Both A and B Both technicians are correct.

Technician A says many torsion bars are adjustable to allow for ride height adjustment. Technician B says torsion bars are usually marked left and right and should never be switched side to side. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B

c. Both A and B Both technicians are correct.

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? a. A only b. B only check c. Both A and B d. Neither A nor B

c. Both A and B Both technicians are correct.

Which of the following electronically controlled suspension sensors is tested by unbolting it with the ignition on, engine off (KOEO) and reviewing scan tool data for correct operation? a. VSS (vehicle speed sensor) b. WSS (wheel speed sensor) c. G-sensor d. Yaw Rate sensor

c. G-sensor

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 check c. Torqued with vehicle weight on suspension d. Torqued with control arm resting on frame

c. Torqued with vehicle weight on suspension The suspension needs to be loaded when bushing retention bolts are tightened. The other choices are wrong.
