1. What is the primary purpose of a vehicle's suspension system?
a. Increase engine performance
b. Provide ride comfort and maintain tire contact
c. Reduce fuel consumption
d. Improve braking efficiency
The suspension system isolates the vehicle body from road shocks
while keeping tires in contact with the road for control and safety.
2. Which type of suspension uses a series of coils and shocks
mounted separately?
a. Leaf spring suspension
b. Torsion bar suspension
c. Coil spring suspension
d. Air suspension
Coil spring suspensions use helical springs with separate shock
absorbers to absorb road shocks.
3. What is the main function of shock absorbers?
a. Increase tire pressure
b. Reduce steering effort
c. Control spring oscillation and vehicle bounce
, d. Align wheels automatically
Shock absorbers dampen the up-and-down motion of springs to
stabilize the vehicle.
4. Which steering system component connects the steering gear to
the wheels?
a. Steering knuckle
b. Tie rod
c. Ball joint
d. Pitman arm
Tie rods transfer steering input from the steering gear to the
wheels.
5. What is the function of a sway bar (stabilizer bar)?
a. Reduce brake fade
b. Improve fuel economy
c. Reduce body roll during cornering
d. Adjust suspension height
A sway bar connects opposite wheels to resist body roll and
improve cornering stability.
6. What could be the likely cause of excessive tire wear on the inside
edges of tires?
a. Low tire pressure
b. Incorrect camber
c. Worn shock absorbers
d. Overinflation
Incorrect negative camber causes inner tire edges to carry more
load, leading to wear.
, 7. What is the purpose of wheel alignment?
a. Increase engine power
b. Reduce fuel consumption
c. Ensure tires roll straight and minimize wear
d. Improve air conditioning efficiency
Proper wheel alignment ensures correct steering geometry,
reducing tire wear and improving handling.
8. Which component allows the suspension to move while the
steering knuckle rotates?
a. Control arm
b. Ball joint
c. Tie rod end
d. Sway bar link
Ball joints allow suspension travel while maintaining steering
control by connecting control arms to steering knuckles.
9. A vehicle pulling to one side while driving straight could be caused
by:
a. Overinflated tires
b. Incorrect wheel alignment
c. Worn spark plugs
d. Low brake fluid
Misaligned wheels can cause the vehicle to drift to one side during
straight-line driving.
10. What is a characteristic of MacPherson strut suspension?
a. Uses leaf springs
b. Combines coil spring and shock in one unit
c. Uses torsion bars only
