Vehicle Steering & Suspension

What are the main components of a vehicle's steering system?

• engine, transmission, wheels

• fuel tank, radiator, air filter

• steering wheel, steering column, steering gear, tie rods, steering knuckles

• brake pads, exhaust pipe, headlights

Name two types of suspension systems commonly found in vehicles.

• Air suspension

• Solid suspension

• Rigid suspension

• Independent suspension, Dependent suspension

Explain the procedures involved in wheel alignment.

• Inspect engine oil

• Check brake fluid level

• Inspect tires, check and adjust camber, caster, and toe angles, center steering wheel, test drive for accuracy.

• Replace windshield wipers

How can you inspect shock absorbers for wear or damage?

• Taste the shock absorbers for oil leaks

• Listen for unusual noises while driving

• Smell the shock absorbers for damage

• Visually inspect for leaks, dents, or damage. Check for oil leaks and bounce each corner of the vehicle.

Distinguish between independent and dependent suspension systems.

• Independent suspension systems are only found in trucks.

• Dependent suspension systems allow each wheel to move independently.

• Independent suspension systems connect the wheels on each side of the vehicle.

• Independent suspension systems allow each wheel to move independently, while dependent suspension systems connect the wheels on each side of the vehicle.

What is the purpose of a steering rack in a vehicle?

• To convert steering wheel rotation into linear motion for turning the wheels.

• To control the windshield wipers

• To adjust the radio volume

• To regulate the air conditioning system

Describe the function of a stabilizer bar in a suspension system.

• The stabilizer bar in a suspension system is used for adjusting tire pressure.

• The stabilizer bar in a suspension system increases body roll and reduces stability by connecting the left and right wheels of a vehicle.

• The stabilizer bar in a suspension system has no impact on body roll or stability.

• The stabilizer bar in a suspension system reduces body roll and improves stability by connecting the left and right wheels of a vehicle.

Why is proper wheel alignment important for vehicle performance?

• Proper wheel alignment ensures all four wheels are pointing in the right direction, reducing tire wear, improving fuel efficiency, and providing better handling and safety.

• Proper wheel alignment has no impact on vehicle performance

• Misaligned wheels provide better fuel efficiency

• Improper wheel alignment leads to increased tire wear

What role do coil springs play in a vehicle's suspension system?

• Coil springs absorb shocks, bumps, support vehicle weight, and maintain ride height.

• Coil springs play a decorative role in the suspension system

• Coil springs are only present in the rear suspension of vehicles

• Coil springs are used to increase fuel efficiency in vehicles

How does a MacPherson strut differ from a double wishbone suspension?

• A MacPherson strut is only found in rear-wheel-drive vehicles, while a double wishbone suspension is only found in front-wheel-drive vehicles.

• A MacPherson strut uses an air suspension system, while a double wishbone suspension uses a hydraulic system.

• A MacPherson strut has three control arms, while a double wishbone suspension has four control arms.

• A MacPherson strut uses a single control arm and a coil spring, while a double wishbone suspension uses two control arms.
