Correct answer: Lost motion within steering gear
A lost motion is caused by excessive play between the rack piston and sector.
Correct answer: Steering arm
The cause of a bent is the steering arm.
Correct answer: Technician Y
Misalignment in the column often leads to high steering effort. This is due to binding. If it were a sheared tube, the sport utility vehicle would have lost steering ability.
Correct answer: Disconnect the power steering return hose from the remote reservoir or pump and allow the fluid to drain
The procedure that should be done first is to disconnect the power steering return hose from the remote reservoir or pump and allow the fluid to drain.
Correct answer: a bent engine cradle
If suspension components are mounted to the cradle, it can cause a bent engine cradle.
Correct answer: Torqued with vehicle weight on suspension
The suspension needs to be loaded when bushing retention bolts are tightened. The other choices are wrong.
Correct answer: Check/adjust the ride height (curb height)
The technician should check/adjust first the ride height (curb height) when aligning a light truck equipped with a torsion bar front suspension.
Correct answer: Worn control arm bushings
Several of these can lead to vibration, but the question stated, “least likely.” With that in mind, the worn control arm bushing would be the least likely of these four options to cause vibration. With a worn control arm bushing, you might also hear clunking noises and battle a wandering steering wheel.
Correct answer: Disconnect the battery ground cable
Disconnect the battery ground cable first when removing the manual steering gear (non-rack-and-pinion type).
Correct answer: worn steering gear mounting bushings.
Worn steering gear mounting bushings is not the cause of the problem.
Correct answer: Rubber bushing is cracked
Cracking of the rubber bushing is an indicator of wear.
Correct answer: Caster
Tire wear is not caused by caster.
Correct answer: Both Technicians
Both of the techs are correct. When the steering column isn’t aligned properly, it commonly creates noise. Tech Y is also right because having low fluid levels in a linkage-assist type power steering column would also create noise.
Correct answer: Neither X nor Y
Neither of the technician is correct.
Correct answer: Both X and Y
Both technicians are right.
Correct answer: It fails the bounce test.
A shock that fails the bounce test is defective regardless of leakage.
Correct answer: Neither X nor Y
Neither of the technician is correct.
Correct answer: Technician X
Safety is always a top priority. You must research the OEM information first. If it’s not done properly, the airbag could deploy and lead to injury.
Correct answer: Excessive toe-in on the front wheels.
When driving straight ahead, excessive toe-in on the front wheels is not the cause of steering pulls to the right.
Correct answer: Base of the steering column
Steering wheel sensors are located at the base of the steering column.
Correct answer: X only
The worn rack-to-frame mounting bushings could be the cause of the vehicle that has a shimmy.
Correct answer: Technician X
If the ride height is incorrect on one side, it can cause a pull. The ride height does affect camber. You will want to correct it before you make any alignment adjustments.
Correct answer: Both X and Y
Both technicians are right.
Correct answer: G-sensor
A G-sensor is tested by unbolting it with the ignition on, engine off (KOEO) and reviewing scan tool data for correct operation.
Correct answer: X only
A worn strut rod bushing could be the cause of a vehicle that pulls to the right when braking.
Correct answer: Both technicians
Both techs are right. If the air assisted shock absorber begins to lose pressure, it might need to be replaced. If the shock leaks, then it’s probably not pressurized to start with. In addition, many air-assisted shock absorbers can become pressurized by the shop air supply.
Correct answer: Disconnect the hoses from the steering gear, cap the lines, and cap the fittings.
Disconnect the hoses from the steering gear, cap the lines, and cap the fittings first when removing the power steering gear.
Correct answer: Y only
Y is correct because the vehicle thrust angle is determined by the rear toe adjustment. Rear camber adjustments are not used by many manufacturers.
Correct answer: Both X and Y
Both technicians are correct.
Correct answer: You must use a safety stand under the lower control arm
Prior to placing the safety stand under the lower control arm, the spring works against the ball joint stud. Once you place the stand there, the load is transferred. Then, an accurate inspection can be performed on the ball joint.
