1. What is the primary function of a vehicle’s suspension system?
A. Increase engine power
B. Provide passenger comfort and tire contact with road
C. Improve fuel efficiency
D. Control emissions
Answer: B
Rationale: Suspension systems absorb road shocks and maintain tire
contact, ensuring comfort and control.
2. Which component connects the steering wheel to the steering gear?
A. Pitman arm
B. Steering column
C. Tie rod
D. Idler arm
Answer: B
Rationale: The steering column transmits driver input from the steering
wheel to the steering gear.
,3. What does camber angle refer to?
A. Forward tilt of the wheel
B. Inward or outward tilt of the wheel
C. Steering axis tilt
D. Tire pressure angle
Answer: B
Rationale: Camber is the inward or outward tilt of the wheel viewed from
the front.
4. Excessive positive camber causes:
A. Inner tire wear
B. Outer tire wear
C. Even tire wear
D. No wear
Answer: B
Rationale: Positive camber tilts the top of the tire outward, increasing
wear on the outer edge.
5. Toe-in refers to:
A. Rearward tilt of wheel
B. Wheels pointing inward
C. Wheels pointing outward
D. Tire rotation
Answer: B
Rationale: Toe-in means the front of the wheels are closer together than
the rear.
6. A worn ball joint may cause:
A. Engine overheating
B. Steering looseness
C. Brake failure
D. Transmission slip
Answer: B
, Rationale: Ball joints connect suspension components and allow
movement; wear leads to looseness.
7. What does caster angle affect?
A. Tire pressure
B. Steering stability
C. Fuel economy
D. Brake force
Answer: B
Rationale: Caster influences directional stability and steering return.
8. A vehicle pulls to one side. Likely cause?
A. Balanced tires
B. Unequal tire pressure
C. New shocks
D. Good alignment
Answer: B
Rationale: Unequal tire pressure can cause pulling due to uneven rolling
resistance.
9. Rack and pinion steering uses:
A. Gearbox
B. Linear motion conversion
C. Hydraulic pump only
D. Chains
Answer: B
Rationale: Rack and pinion converts rotational motion into linear motion.
10.Power steering fluid is used to:
A. Cool engine
B. Lubricate brakes
C. Assist steering effort
