Q&A | Instant Download Pdf
1. A vehicle pulls to the right when driving on a straight, level road. What
is the most likely cause?
A) Worn struts
B) Unequal tire pressure
C) Faulty sway bar
D) Loose control arm
Rationale: Unequal tire pressure can cause the vehicle to pull toward
the side with lower pressure.
2. What is the primary function of the sway bar in a vehicle suspension
system?
A) Reduce ride height
B) Reduce body roll
C) Improve braking efficiency
, D) Maintain tire pressure
Rationale: The sway bar connects opposite wheels and reduces body
roll during cornering.
3. Which type of steering system uses a hydraulic pump to assist the
driver in turning the wheels?
A) Manual steering
B) Power steering
C) Rack-and-pinion steering
D) Recirculating ball steering
Rationale: Power steering uses a hydraulic pump to reduce driver
effort when turning the wheels.
4. Excessive tire wear on one edge of a tire usually indicates:
A) Overinflation
B) Underinflation
C) Misalignment
D) Worn shock absorber
Rationale: Misalignment can cause uneven tire wear on one side.
5. Which component absorbs shocks from the road and dampens
suspension movement?
A) Coil spring
B) Shock absorber
C) Control arm
D) Stabilizer bar
, Rationale: Shock absorbers control the up-and-down motion of the
suspension, providing a smoother ride.
6. What is the purpose of caster in front-wheel alignment?
A) Prevent tire wear
B) Reduce body roll
C) Improve straight-line stability
D) Assist with turning radius
Rationale: Caster is the forward or backward tilt of the steering axis
that affects directional stability.
7. A vehicle’s front wheels are toe-in. What is the expected effect?
A) Vehicle will pull left
B) Tires will wear on the outer edges
C) Tires will wear on the inner edges
D) Steering will be loose
Rationale: Toe-in causes the outer edges of the tires to wear faster.
8. Which type of suspension system uses a torsion bar to support vehicle
weight?
A) Leaf spring
B) Coil spring
C) Torsion bar
D) Air spring
Rationale: Torsion bars twist along their axis to act as a spring.
, 9. Which component connects the steering gear to the steering
knuckles?
A) Tie rod ends
B) Pitman arm
C) Control arm
D) Sway bar
Rationale: The pitman arm transfers motion from the steering gear
to the linkage controlling the wheels.
10. What is the primary purpose of wheel alignment?
A) Improve fuel efficiency
B) Prevent brake fade
C) Reduce tire wear and improve handling
D) Increase suspension travel
Rationale: Proper alignment ensures even tire wear and stable
handling.
11. Which steering system component reduces the effort required
to turn the wheels?
A) Control arm
B) Tie rod
C) Power steering pump
D) Steering knuckle
Rationale: The power steering pump provides hydraulic assist,
reducing steering effort.
