1. What is the primary purpose of a vehicle’s suspension system?
A. Increase engine power
B. Improve fuel economy
C. Maintain tire contact with the road surface
D. Reduce brake wear
Rationale: The suspension system keeps tires in contact with the road
for stability, control, and comfort.
2. Worn shock absorbers primarily cause:
A. Increased engine noise
B. Excessive vehicle bouncing
C. Transmission slipping
D. Brake fade
,Rationale: Worn shocks cannot control spring oscillation, causing
bouncing.
3. A MacPherson strut assembly combines:
A. Leaf spring and axle
B. Control arm and torsion bar
C. Shock absorber and coil spring
D. Stabilizer bar and knuckle
Rationale: A strut integrates damping and spring functions.
4. What component helps reduce body roll during cornering?
A. Tie rod
B. Ball joint
C. Stabilizer (sway) bar
D. Idler arm
Rationale: The sway bar distributes force to reduce lean during turns.
5. Uneven tire wear on both edges typically indicates:
,A. Overinflation
B. Underinflation
C. Misaligned camber
D. Worn shocks
Rationale: Low tire pressure causes both edges to wear faster.
6. Excessive negative camber will cause wear on:
A. Center of tire
B. Inside edge of tire
C. Outside edge of tire
D. No wear
Rationale: Negative camber tilts the tire inward, wearing the inside
edge.
7. Toe-in adjustment means:
A. Tires point outward at front
B. Tires are parallel
C. Front of tires point inward slightly
D. Rear wheels steer
Rationale: Toe-in means front edges are closer than rear edges.
, 8. What is the function of a ball joint?
A. Control engine vibration
B. Allow steering and suspension movement
C. Increase brake pressure
D. Reduce tire friction
Rationale: Ball joints act as pivot points between control arms and
knuckles.
9. A loose steering wheel with delayed response may indicate:
A. Overinflated tires
B. Excessive steering linkage play
C. Stuck brake caliper
D. Faulty alternator
Rationale: Loose linkage causes steering delay.
10. Power steering fluid is primarily used to:
A. Lubricate engine valves
B. Cool transmission
C. Assist steering effort reduction
