Understanding Four Wheel Alignment

What is the primary purpose of a four-wheel alignment in a vehicle?

• To increase the vehicle's speed

• To ensure all wheels are parallel and perpendicular to the ground

• To enhance the vehicle's aesthetic appearance

• To improve the vehicle's fuel efficiency

Which of the following is NOT an alignment angle?

• Caster

• Camber

• Toe

• Thrust

What does the camber angle refer to in wheel alignment?

• The angle of the steering wheel

• The angle of the wheel relative to the vertical axis

• The angle of the wheel relative to the horizontal axis

• The angle of the wheel relative to the vehicle's body

How does a positive caster angle affect vehicle handling?

• It makes the vehicle more stable at high speeds

• It makes the vehicle more difficult to steer

• It causes the vehicle to drift to the left

• It improves fuel efficiency

What is the effect of incorrect toe adjustment on a vehicle?

• It can cause uneven tire wear

• It improves the vehicle's acceleration

• It enhances the vehicle's braking performance

• It reduces the vehicle's turning radius

Which alignment angle is primarily responsible for the vehicle's directional stability?

• Camber

• Caster

• Toe

• Thrust

What is the typical range for camber angle in most vehicles?

Why is it important to have a four-wheel alignment rather than just a two-wheel alignment?

• It is cheaper than a two-wheel alignment

• It ensures all four wheels are aligned, improving overall vehicle handling

• It is required by law

• It increases the vehicle's horsepower

What is the consequence of having a negative camber angle?

• Improved straight-line stability

• Increased tire wear on the inner edge

• Reduced cornering performance

• Enhanced fuel efficiency

Which of the following best describes the toe angle?

• The angle between the wheel and the vehicle's body

• The angle between the wheel and the vertical axis

• The angle between the direction the wheels are pointing and the centerline of the vehicle

• The angle between the wheel and the horizontal axis
