1. What is the primary function of a vehicle’s suspension system?
A. Increase engine power
B. Improve fuel economy
C. Support vehicle weight and maintain tire contact with the road
D. Reduce exhaust noise
The suspension system supports the vehicle’s weight, absorbs road shocks,
and keeps tires in contact with the road for control and comfort.
2. Which component controls spring oscillation?
A. Coil spring
B. Leaf spring
C. Shock absorber
D. Stabilizer bar
Shock absorbers dampen spring movement to prevent excessive bouncing.
3. A vehicle pulls to the right while driving straight. Which alignment angle is
most likely incorrect?
A. Toe
B. Caster
C. Camber
D. Thrust angle
Caster affects directional stability and straight-line tracking.
,4. Excessive positive camber will cause which condition?
A. Inside tire wear
B. Feathered tread
C. Outside tire wear
D. Center tread wear
Positive camber tilts the top of the tire outward, wearing the outer edge.
5. What is the purpose of a stabilizer (sway) bar?
A. Absorb bumps
B. Control steering ratio
C. Reduce body roll during cornering
D. Adjust ride height
A stabilizer bar limits body roll by transferring force from one side to the
other.
6. Which steering system uses a worm gear and sector shaft?
A. Rack-and-pinion
B. Recirculating ball
C. Electric power steering
D. Variable assist steering
Recirculating ball systems commonly use a worm gear and sector shaft.
7. Power steering fluid leaks at the rack boots usually indicate a failure of
which component?
A. Tie-rod ends
B. Pump
C. Rack seals
D. Steering column
Fluid inside rack boots indicates internal rack seal failure.
8. What alignment angle primarily affects tire wear?
A. Caster
B. Camber
C. Steering axis inclination
D. Included angle
Camber has the greatest effect on edge tire wear.
, 9. A worn ball joint may cause which symptom?
A. Hard steering
B. Clunking noise over bumps
C. Engine vibration
D. Brake fade
Loose ball joints often produce clunking noises when suspension loads
change.
10.Which component locates the axle on a leaf-spring suspension?
A. Shock absorber
B. Leaf spring
C. Stabilizer bar
D. Control arm
Leaf springs both support weight and locate the axle.
11.Toe-out on turns is mainly controlled by which component?
A. Tie rods
B. Steering arms and linkage geometry
C. Ball joints
D. Strut mounts
Ackermann geometry in steering arms provides proper toe-out on turns.
12.Which condition will cause steering wheel shimmy?
A. Incorrect caster
B. Unbalanced front wheels
C. Incorrect thrust angle
D. Worn strut bearings
Wheel imbalance is a common cause of steering wheel vibration.
13.What does positive caster improve?
A. Tire wear
B. Straight-line stability
C. Steering effort
D. Turning radius
Positive caster helps the wheels return to center and improves stability.
14.Which suspension design uses a strut as a structural member?
A. Double wishbone
