Technician X states that a misaligned steering column input can result in noise. Technician Y states that if the linkage-assist type power steering column is low on lubricant, there is noise while turning the wheel. Who is correct?

Correct! Wrong!

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.

Technician X says front wheel setback is usually caused by worn suspension components. Technician Y says a slight front wheel setback causes steering pull. Who is right?

Correct! Wrong!

Correct answer: Neither X nor Y

Neither of the technician is correct.

Two technicians are discussing the ride height measuring procedure. Technician X says bent components can cause incorrect ride height. Technician Y says for proper measurement of the ride height, the vehicle must have a full tank of fuel. Who is right?

Correct! Wrong!

Correct answer: Both X and Y

Both technicians are right.

Which of the following applies when a shock absorber needs to be replaced due to a fluid leak?

Correct! Wrong!

Correct answer: It fails the bounce test.

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

A vehicle wanders while being driven on level roads. Technician X says that too much negative camber could be the cause. Technician Y says that too much positive caster could be the cause. Who is right?

Correct! Wrong!

Correct answer: Neither X nor Y

Neither of the technician is correct.

While working on a steering column, Technician X says you must consult the online service information to get the proper airbag disabling procedure. Technician Y says that the flexible coupling or U-joint needs to be taken off before you remove the steering wheel. Who is correct?

Correct! Wrong!

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.

On a truck with a long-and-short arm front suspension and a leaf spring rear suspension, the steering pulls to the right while driving straight ahead. All of the following defects could be the cause of the problem EXCEPT:

Correct! Wrong!

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.

Which of the following location is the steering wheel sensor typically located?

Correct! Wrong!

Correct answer: Base of the steering column

Steering wheel sensors are located at the base of the steering column.

A vehicle with rack and pinion steering has a shimmy. Technician X says that worn rack-to-frame mounting bushings could be the cause. Technician Y says that a binding steering shaft U-joint could be the cause. Who is right?

Correct! Wrong!

Correct answer: X only

The worn rack-to-frame mounting bushings could be the cause of the vehicle that has a shimmy.

While discussing ride height of a vehicle, Technician X states that when it’s too low, the vehicle might pull to one side. Technician Y believes that the ride height won’t affect front camber. Who is correct?

Correct! Wrong!

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.

While discussing front cradle alignment, Technician X says the cradle may be measured at various locations to determine if it is bent. Technician Y says on some cradles an alignment hole in the cradle must be aligned with a hole in the chassis. Who is right?

Correct! Wrong!

Correct answer: Both X and Y

Both technicians are right.

Correct! Wrong!

Correct answer: X only

A worn strut rod bushing could be the cause of a vehicle that pulls to the right when braking.

While talking about air shocks, Technician X states that some can be pressurized with the shop air hose. Technician Y states that if the shock absorber begins to lose air pressure, replacement might be required. Who is correct?

Correct! Wrong!

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.

Which procedure should be performed first to remove the power steering gear (non-rack-and-pinion type)?

Correct! Wrong!

Correct answer: Disconnect the hoses from the steering gear, cap the lines, and cap the fittings.
