Understanding Four Wheel Alignment

Front

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

Back

To ensure all wheels are parallel and perpendicular to the ground

Front

Which of the following is NOT an alignment angle? Caster, Camber, Toe, Thrust

Back

Thrust

Front

What does the camber angle refer to in wheel alignment?

Back

The angle of the wheel relative to the vertical axis

Front

How does a positive caster angle affect vehicle handling?

Back

It makes the vehicle more stable at high speeds

Front

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

Back

It can cause uneven tire wear

Front

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

Back

Caster

Front

What is the typical range for camber angle in most vehicles? Options: 0° to 1°, -1° to 1°, -2° to 2°, -3° to 3°

Back

-2° to 2°

Front

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

Back

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

Front

What is the consequence of having a negative camber angle?

Back

Increased tire wear on the inner edge

Front

Which of the following best describes the toe angle?
Options:
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

Back

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