1. A vehicle pulls to the right while driving straight on a level road.
What is the most likely cause?
a) Worn shock absorbers
b) Misaligned front wheels
c) Low tire pressure on left side
d) Steering wheel off-center
b) Misaligned front wheels
Rationale: Wheel misalignment can cause the vehicle to pull to
one side due to uneven tire contact and steering geometry.
2. Which component connects the steering knuckle to the control
arm?
a) Tie rod end
b) Ball joint
c) Idler arm
d) Pitman arm
b) Ball joint
Rationale: Ball joints allow the steering knuckle to pivot while
maintaining a connection to the control arm.
,3. Excessive tire wear on the inside edge of the front tires typically
indicates:
a) Excessive positive camber
b) Excessive negative camber
c) Toe-in
d) Toe-out
b) Excessive negative camber
Rationale: Negative camber tilts the top of the tire inward,
causing the inner edge to wear faster.
4. What is the purpose of a sway bar (stabilizer bar)?
a) Reduce body roll during cornering
b) Absorb vertical shocks
c) Align the wheels
d) Control steering effort
a) Reduce body roll during cornering
Rationale: The sway bar links the left and right suspension to
resist body roll in turns.
5. Which type of suspension uses a coil spring and shock absorber
mounted separately on the control arm?
a) Torsion bar suspension
b) MacPherson strut
c) Leaf spring suspension
d) Air suspension
b) MacPherson strut
Rationale: MacPherson struts integrate the spring and shock into
a single unit but are mounted to allow independent wheel
movement.
6. A clunking noise over bumps from the front suspension is most
likely caused by:
, a) Loose tie rod ends
b) Worn ball joints
c) Broken sway bar links
d) Worn control arm bushings
b) Worn ball joints
Rationale: Ball joints allow pivoting; when worn, they can
produce clunking or knocking noises over bumps.
7. Steering wheel vibration at highway speeds is usually caused by:
a) Worn shocks
b) Unequal tire wear
c) Misaligned wheels
d) Loose power steering belt
b) Unequal tire wear
Rationale: Tire imbalance or uneven wear can cause vibrations
that are felt through the steering wheel at high speeds.
8. Which system provides power assistance to reduce steering
effort?
a) Rack-and-pinion steering
b) Power steering
c) Manual steering
d) Four-wheel steering
b) Power steering
Rationale: Power steering systems use hydraulic or electric assist
to reduce the effort needed to turn the wheels.
9. Excessive free play in the steering wheel is usually caused by:
a) Worn tie rod ends or pitman arm
b) Misaligned wheels
c) Low power steering fluid
d) Worn shocks
, a) Worn tie rod ends or pitman arm
Rationale: Loose steering components allow excessive
movement before the wheels respond.
10. What is the main function of the strut mount?
a) Connect sway bar to frame
b) Attach strut to vehicle body and isolate vibration
c) Control camber angle
d) Support ball joint
b) Attach strut to vehicle body and isolate vibration
Rationale: Strut mounts secure the strut to the body and often
contain a bearing or bushing to reduce noise and vibration.
11. What does caster angle affect?
a) Camber wear
b) Steering effort and straight-line stability
c) Toe-in adjustment
d) Shock absorber travel
b) Steering effort and straight-line stability
Rationale: Caster tilts the steering axis fore or aft, influencing
stability and returnability of the steering wheel.
12. What is the purpose of a tie rod?
a) Connect control arm to steering knuckle
b) Connect steering gear to steering knuckle
c) Support sway bar
d) Attach shock absorber
b) Connect steering gear to steering knuckle
Rationale: Tie rods transmit steering input from the steering rack
or box to the wheels.
13. Which suspension type is most likely to cause camber
changes during suspension travel?
