Exam Questions And Correct Answers

ASE A4 Suspension & Steering Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• Which component is primarily responsible for controlling lateral

movement of the vehicle body?

• Shock absorber
• Coil spring
• Sway bar (stabilizer bar)
• Control arm

Rationale: The sway bar connects opposite wheels and resists body

roll during cornering, controlling lateral movement.

• What is the primary function of a MacPherson strut?
• Steering control
• Suspension support and damping
• Brake force distribution 1 / 4

• Wheel alignment

Rationale: MacPherson struts combine a shock absorber with a coil

spring, supporting the vehicle and controlling suspension motion.

• A vehicle pulls to the left while driving straight on a level road. What is

the most likely cause?

• Low engine oil
• Bad wheel bearings
• Incorrect wheel alignment
• Loose sway bar

Rationale: Misalignment, especially toe or camber issues, can cause

the vehicle to drift to one side.

• Which type of steering system uses a hydraulic piston to assist turning

effort?

• Rack-and-pinion
• Manual recirculating ball
• Hydraulic power steering
• Electric assist only

Rationale: Hydraulic power steering uses fluid pressure to reduce

steering effort.

• What is the purpose of a ball joint in a suspension system?
• Control spring rate
• Allow pivoting of control arms for steering and suspension

movement 2 / 4

• Reduce brake fade
• Absorb shocks

Rationale: Ball joints provide a pivot point for control arms while

allowing steering and suspension articulation.

• A vehicle with independent front suspension exhibits uneven tire wear

on the inside edge. What is the likely cause?

• Loose tie rod ends
• Incorrect camber angle
• Worn shock absorbers
• Low tire pressure

Rationale: Negative or excessive camber causes tires to wear more

on the inner edge.

• Which component connects the steering gear to the steering knuckle?
• Control arm
• Pitman arm
• Sway bar link
• Tie rod

Rationale: Tie rods transmit steering input from the gear to the

wheels.

• When inspecting a strut assembly, a technician notices oil leakage.

What should be done?

• Top off with engine oil
• Replace the strut 3 / 4

• Clean the strut and continue
• Tighten mounting bolts only

Rationale: Oil leakage indicates the strut is no longer damping

properly and must be replaced.

• What is the main purpose of a shock absorber?
• Reduce engine vibration
• Control spring oscillation and vehicle bounce
• Improve braking efficiency
• Maintain tire pressure

Rationale: Shock absorbers dampen the up-and-down motion of

springs for ride comfort and control.

• A vehicle exhibits excessive body roll during turns. Which

component should be inspected?

• Ball joints
• Tie rods
• Sway bar and sway bar links
• Control arm bushings

Rationale: The sway bar reduces body roll, and worn links or

bushings can increase roll.

• What is the primary function of a control arm bushing?
• Connects wheel hub to axle
• Absorbs suspension vibrations and allows pivoting
• Maintains tire pressure
