Sample ASE H5 Suspension & Steering (Transit Bus) Practice Questions

Try these sample questions to test your ASE H5 Suspension & Steering (Transit Bus) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A transit bus has excessive steering wheel free play and wandering on the highway. Which component should be inspected FIRST?

A.Steering gear sector shaft adjustment and linkage joints for wear

B.The kneeling system air bag

C.The radius rod bushings on the rear axle

D.The windshield wiper linkage

Explanation: Excessive free play and wander typically come from lost motion in the steering system. The steering gear over-center (sector lash) adjustment and worn linkage joints such as drag link and tie-rod ends are the primary sources and should be inspected first.

2Tech A says an integral hydraulic power steering gear uses a torsion bar to sense steering effort. Tech B says the rotary valve directs pump pressure to either side of the gear piston. Who is correct?

A.Tech B only

B.Both Tech A and Tech B

C.Neither Tech A nor Tech B

D.Tech A only

Explanation: In an integral power steering gear, a torsion bar twists in proportion to steering effort and positions the rotary spool valve. The valve then directs pump pressure to the appropriate side of the rack piston to provide assist. Both technicians are correct.

3A transit bus power steering pump is noisy and produces foamy fluid. The MOST likely cause is:

A.Excessive caster on the steered axle

B.A seized tie-rod end

C.Air being drawn into the system through a low reservoir or loose suction hose

D.A worn pitman arm

Explanation: Foamy (aerated) fluid and pump noise indicate air is entering the system, commonly through a low fluid level or a loose/cracked low-pressure suction line. Aerated fluid is compressible and causes whine and erratic assist.

4During a steering linkage inspection on a transit bus, a technician finds a drag link end with detectable axial play. The correct action is to:

A.Tighten the steering gear sector lash

B.Increase power steering pump pressure

C.Add grease until the play disappears

D.Replace the drag link or worn end

Explanation: A drag link or tie-rod end with measurable axial (in-and-out) play is worn beyond serviceable limits and must be replaced. Grease cannot compensate for a worn ball-and-socket joint, and worn joints cause wander and bump steer.

5A transit bus has hard steering only during low-speed parking maneuvers but steers normally at road speed. The MOST likely cause is:

A.Low power steering pump output at low engine rpm or a failing pump

B.Excessive toe-out on turns

C.A leaking kneeling valve

D.A worn rear shock absorber

Explanation: Hardest steering occurs at low speed when the pump turns slowest and demand is highest. A pump with low output, a slipping belt, or worn pump components cannot supply enough flow at idle, causing hard parking-lot steering while road-speed steering feels acceptable.

6Which inspection BEST evaluates kingpin wear on a transit bus front axle?

A.Measuring tire tread depth

B.Raising the wheel and checking vertical and lateral movement at the knuckle with a dial indicator

C.Checking power steering fluid color

D.Measuring steering wheel diameter

Explanation: Kingpin wear is checked by raising the front wheel off the ground and measuring vertical (axial) and lateral movement at the steering knuckle, often with a dial indicator and a pry bar, comparing against the manufacturer's wear specification. Movement that exceeds the manufacturer limit means the kingpin and bushings must be replaced to restore safe steering and correct geometry.

7A transit bus pulls steadily to the right with no braking applied and tires are properly inflated. Which is the MOST likely steering/alignment cause?

A.Correct thrust angle

B.Equal caster on both sides

C.Unequal caster or camber between the left and right steered wheels

D.A worn rear sway bar link

Explanation: A steady non-brake pull is commonly caused by a side-to-side difference in caster or camber. The bus pulls toward the side with the lower (more negative) caster or the more positive camber. Equal settings would not cause a pull.

8On a transit bus air suspension, the height control valve's primary function is to:

A.Control the power steering assist level

B.Engage the kneeling feature automatically while driving

C.Regulate brake application pressure

D.Maintain a constant chassis ride height by adding or exhausting air from the air springs

Explanation: The height control (leveling) valve senses chassis-to-axle distance and adds air to or exhausts air from the air springs to keep ride height constant regardless of load, maintaining correct suspension geometry and ride quality. If the valve cannot maintain height correctly, the bus rides at the wrong attitude, which also affects driveline angle and steering geometry.

9A transit bus sits low at one rear corner overnight but rises to correct height shortly after the engine starts. The MOST likely cause is:

A.An air leak at the air spring or fitting that bleeds down when the system is not pressurized

B.Excessive positive caster

C.A worn tie-rod end

D.A normal condition requiring no repair

Explanation: Sitting low when parked and rising once air pressure is restored points to a slow air leak at an air spring, fitting, or line at that corner. With the engine off the leak bleeds the bag down; when the compressor refills the system the height control valve restores ride height.

10Tech A says a hub-piloted wheel system centers the wheel on the hub pilot, not on the lug studs. Tech B says hub-piloted wheel fasteners must be tightened to the specified torque in the correct sequence. Who is correct?

A.Tech B only

B.Both Tech A and Tech B

C.Neither Tech A nor Tech B

D.Tech A only

Explanation: Hub-piloted (unimount) wheels are centered by the machined hub pilot rather than by the studs, and they require single-cap nuts tightened to the manufacturer's specified torque in the proper cross/star sequence to seat evenly and prevent loosening. Both technicians are correct.

ASE H5 Suspension & Steering (Transit Bus) Study Tips from Top Performers

1Weight study time by the official blueprint: suspension is 51% of the test, so prioritize air springs, height control/leveling valves, the kneeling system, shocks, and radius rods.

2Practice diagnostic reasoning, not just facts: many H5 items describe a symptom and ask for the most likely cause or the correct next step, including Technician A / Technician B questions.

3Master air suspension airflow logic: trace how a height control valve adds or exhausts air and how a bent linkage or stuck valve shifts ride height up or down.

4Tie tire wear patterns to root causes: shoulder wear to under-inflation, center wear to over-inflation, feathering to toe, cupping to worn shocks.

5Drill safety procedures: deflating tires before demount, using a safety cage for multi-piece rims, exhausting air springs before service, and correct hub-piloted wheel torque and re-torque.
