Suspension & Steering

Multiple Choice

A technician is replacing tires on a vehicle equipped with TPMS sensors mounted on the valve stems. Tech A says that when using the tire changer shovel to break the bead loose from the wheel, the valve stem should be positioned approximately 90⁰ from the shovel. Tech B says that after the tire and wheel assemblies are installed on the vehicle, running a TPMS relearn procedure may be required. Who is right?

• Tech B Only

• Both

• Neither

Multiple Choice

When inspecting a vehicle’s power steering system, the technician observes a fluid leak coming from the high pressure hose crimp connection. To repair the leak the tech should:

• Tighten the crimp connection.
• Add more fluid to the reservoir.
• Replace the high pressure hose.
• Replace the power steering pump.

Multiple Choice

When checking shock absorbers, any of these are reasons for replacement EXCEPT:

• The car bounces more than twice on bounce test

• Surface rust on housing

• bent shaft

• Leaking fluid from the shock absorber.

Multiple Choice

A customer states the left front tire loses air. Any of these could be the cause EXCEPT:

• Loose Schrader valve

• corrosion at the tire bead area

• a cracked valve stem

•       excessive runout (warpage) in the wheel

Multiple Choice

A TPMS sensor is being replaced. Tech A says that on some vehicles, a magnet is used to activate the new sensor. Tech B says that on some vehicles, the new sensor may have to be relearned by the TPMS module. Who is right?

Multiple Choice

The tires of a vehicle are being rotated and balanced. Tech A says that the wheel weight retaining clips must be matched to the rim profile. Tech B says that directional tires are rotated in a criss-cross pattern. Who is right?

• Tech A only

• Tech B only

• Both

• Neither

Multiple Choice

A tech is diagnosing a vehicle with hard steering when cold. After verifying the symptom, the tech should:

• Check tire pressure
• Inspect the brake pads
• Check for related TSB's

• Replace the pump

Multiple Choice

A vehicle began to pull (drift) to one side after the tires were rotated. It did not pull before. No other procedures were performed. The pull could be caused by:

• Misaligned steering wheel
• Faulty brake system
• Worn suspension components
• Radial ply tire pull

Multiple Choice

A high pitched squeal is heard when the steering wheel is turned to a full lock position. Which of these could be the cause?

• Low power steering fluid or a failing power steering pump.
• Damaged suspension components
• improper fluid

• loose drive belt

Multiple Choice

The designation P205/70R/15 appears on a tire. The number 205 indicates the:

• The tire's load capacity in pounds.
• The tire's aspect ratio.
• cross sectional width (tread) in millimeters.

• The tire's diameter in inches.

Multiple Choice

A vehicle is being prepared for an alignment. Tech A says that the tire pressures should be checked and adjusted as needed. Tech B says that the vehicle should be loaded with weight to simulate the weight normally carried in the vehicle. Who is right?

• Tech A only

• Tech B only

• Both

• Neither

Multiple Choice

Tech A says that when reinstalling a wheel and tire assembly on a vehicle, the lug nuts should be tightened using a torque wrench. Tech B says the lug nuts should be tightened in a circular pattern. Who is right?

• Tech A only

• Tech B only

• Neither

Multiple Choice

Tech A says that weak springs can affect ride height. Tech B says that worn stabilizer bushings can affect ride height. Who is correct?

• Neither

Multiple Choice

. Tech A says that tire rotation helps to extend tire life. Tech B says that directional tires should be rotated in an “X” pattern. Who is right?

• Tech A only

• Tech B only

• Both

• Neither

Multiple Choice

Tech A says that excessive play of the inner tie rod indicates that the inner tie rod must be replaced. Tech B says that a torn bellows boot indicates the outer tie rod must be replaced. Who is correct?

• Tech A only

• Tech B only

• Both

• Neither

Multiple Choice

Tire pressure is being checked and adjusted at ambient temperature. Tech A says that the correct pressure for the vehicle may be found on a placard on the driver’s door. Tech B says that the correct pressure may be found on the tire sidewall. Who is correct?

• Tech A only

• Tech B only

• Both

• Neither

Multiple Choice

. During parking maneuvers, a vehicle equipped with power steering makes a growling noise and the steering wheel is hard to turn. Which of these could be the cause?

• Incorrect tire pressure affecting handling
• Worn tires causing steering resistance
• Low power steering fluid or a failing power steering pump.
• Faulty brake system causing drag

Multiple Choice

The warning indicator shown below is used to alert the driver of:

• Engine Misfire

• burned out bulb

• ABS issue

• Low tire pressure

Multiple Choice

Tires are being replaced on a vehicle originally equipped with P205/60R16 92H tires. Tech A says that P225/60R15 92H tires are a suitable replacement. Tech B says that P205/60R16 92V tires are a suitable replacement. Who is right?

• Tech A only

• Tech B only

• Both

• Neither

Multiple Choice

A worn upper strut mount may cause any of these EXCEPT:

• Noise while turning

• binding steering

• change in alignment angles

• play at the knuckle

Multiple Choice

On a coil spring suspension system, the coil springs perform all these functions EXCEPT:

• establish ride height

• prevent wheels from bouncing

• carry weight of vehicle

• absorb road shock

Multiple Choice

Multiple Choice

A vehicle’s engine stalls when the steering wheel is turned all the way to the left or right. This could be caused by:
