Understanding Automotive Suspension Systems

Which of the following is a primary function of an automotive suspension system?

• To increase engine power

• To absorb shocks from the road

• To improve fuel efficiency

• To control emissions

Which component connects the wheel to the vehicle’s frame and allows for up and down movement?

• Brake caliper

• Control arm

• Radiator

• Exhaust manifold

What type of suspension system uses a rigid beam that connects the left and right wheels?

• Independent suspension

• MacPherson strut

• Leaf spring suspension

• Solid axle suspension

Which of the following is NOT a typical component of a suspension system?

• Shock absorber

• Leaf spring

• Alternator

• Coil spring

A car is experiencing excessive bouncing after hitting bumps. Which suspension component is most likely failing?

• Shock absorber

• Brake pad

• Fuel injector

• Timing belt

Compare the main difference between independent and dependent suspension systems.

• Independent systems allow each wheel to move separately, while dependent systems connect wheels with a solid axle

• Dependent systems use hydraulic fluid, while independent systems do not

• Independent systems are only used in trucks, while dependent systems are used in cars

• Dependent systems are always more expensive than independent systems

A vehicle designer wants to improve both ride comfort and handling. Which combination of suspension components should they focus on optimizing?

• Shock absorbers and springs

• Exhaust and intake manifolds

• Brake pads and rotors

• Fuel tank and fuel pump

Explain why a MacPherson strut suspension might be chosen for a compact car design.

• It is lightweight and saves space, making it ideal for smaller vehicles

• It provides the highest ground clearance

• It is the cheapest to manufacture for all vehicle types

• It is only used in heavy-duty trucks

A customer complains that their car sways excessively during cornering. Using your knowledge of suspension systems, what could be a likely cause and how would you address it?

• Worn anti-roll bar bushings; replace the bushings

• Dirty air filter; clean or replace the filter

• Low tire pressure; inflate the tires

• Faulty spark plugs; replace the spark plugs

Given a scenario where a vehicle’s suspension system is making loud clunking noises over bumps, outline a logical sequence of steps you would take to diagnose the problem.

• Inspect suspension components for wear or damage, check for loose bolts, and test drive to replicate the noise

• Change the engine oil, check the battery, and replace the air filter

• Wash the car, check tire pressure, and refill windshield washer fluid

• Replace the transmission fluid, check the alternator, and inspect the exhaust system
