Vehicle Wheel Alignment Quiz

Why is proper wheel alignment crucial for vehicle safety?

• It maintains handling and stability.

• It increases the vehicle's running costs

• It helps the vehicle's tyres to wear unevenly

• It ensures the vehicle's tyre pressures increase in low temperatures

Answer explanation

Proper wheel alignment is crucial for vehicle safety because it maintains handling and stability. Misalignment can lead to uneven tire wear, poor handling, and increased risk of accidents.

What equipment is used to measure wheel alignment angles?

• A screwdriver and ratchet

• A lift, computer module, and cameras

• A hammer

• Spirit level

Answer explanation

To measure wheel alignment angles accurately, a lift, computer module, and cameras are used. This equipment allows for precise adjustments and diagnostics, unlike the other tools listed, which are not suitable for this task.

How does a positive camber angle affect the wheels?

• The top of the wheel tilts inwards.

• The top of the wheel tilts outwards.

• The wheel becomes square. to the wing

• The wheel becomes oval

Answer explanation

A positive camber angle causes the top of the wheel to tilt outwards. This adjustment can improve stability and handling during cornering, making it the correct choice.

What does a 'toe in' angle mean for the wheels?

• The wheels point towards each other.

• The wheels are horizontal.

• The wheels point away from each other.

• The wheels are perfectly vertical.

Answer explanation

A 'toe in' angle means the front of the wheels is angled towards each other. This alignment can improve stability and handling, making the correct choice "The wheels point towards each other."

What is the effect of a positive caster angle on vehicle handling?

• It improves traction and grip during cornering.

• It makes the vehicle fly.

• It causes the vehicle to spin uncontrollably.

• It makes the vehicle invisible.

Answer explanation

A positive caster angle enhances vehicle stability and improves traction and grip during cornering, allowing for better handling and control. This is why the correct answer is that it improves traction and grip during cornering.

What does the steering axis inclination (SI) help with?

• It makes the vehicle invisible.

• It increases the vehicle's weight.

• It stabilises the steering by providing a self-centring effect.

• It de-stabilises the steering.

Answer explanation

The steering axis inclination (SI) helps stabilize the steering by providing a self-centering effect, which enhances vehicle control and handling, making it easier for the driver to maintain a straight path.

What is the thrust angle's role in vehicle alignment?

• It increases the vehicle's weight.

• It ensures the vehicle tracks straight.

• It changes the vehicle's colour

• It makes the vehicle fly.

Answer explanation

The thrust angle is crucial for vehicle alignment as it ensures the vehicle tracks straight. Proper alignment helps maintain stability and control while driving, preventing uneven tire wear and enhancing safety.

What is a potential consequence of severe misalignment?

• The vehicle changes colour.

• The vehicle travels slightly sideways while moving forward.

• The vehicle becomes weightless.

• The vehicle becomes invisible.

Answer explanation

Severe misalignment can cause the vehicle to travel slightly sideways while moving forward, indicating that the wheels are not properly aligned. This affects handling and can lead to further mechanical issues.

What is one benefit of accurate wheel alignment?

• It maximises tyre life.

• It changes the vehicle's colour.

• It increases the vehicle's weight.

• It makes the vehicle fly.

Answer explanation

Accurate wheel alignment ensures that tires wear evenly and last longer, maximizing tire life. This prevents premature tire replacement and enhances vehicle performance.

How often is it recommended to get your wheels aligned?

• Every 6,000 miles or every 1 year

• Every 100 miles

• Every 30,000 miles

• Every 1,000 miles

Answer explanation

It is recommended to get your wheels aligned every 10,000 km or every 1 year to ensure optimal vehicle handling and tire longevity. This frequency helps maintain proper alignment and prevents uneven tire wear.
