Wheel Alignment Quiz

What is camber?

• The angular displacement of the steering axis from the vertical axis

• The direction the tires are pointed relative to the vehicle center line

• A measure of the tire's centerline relative to the road surface

• The angle between the steering axis and the vertical line

What is the effect of positive camber combined with steering axis inclination?

• Reduces steering effort and minimizes tire wear

• Increases the peak tire grip during straight-line driving

• Increases steering effort and tire wear

• Improves cornering for racing cars

What is the typical camber setting for street-driven vehicles?

• Small negative camber

• Large positive camber

• Large negative camber

• Neutral camber

What is the downside of negative camber?

• Causes excessive body roll

• Increases tire wear during cornering

• Increases steering effort

• Reduces the peak tire grip during straight-line driving

Which suspension design can generate more camber gain?

• Torsion beam suspension

• Leaf spring suspension

• Double wishbone setup

• McPherson strut suspension

What is caster?

• The angle between the steering axis and the vertical line

• The measure of the tire's centerline relative to the road surface

• The direction the tires are pointed relative to the vehicle center line

• The angular displacement of the steering axis from the vertical axis

What is an example of positive caster?

• The wheels of a skateboard

• The rear wheels of a car

• The front wheels of a shopping cart

• The rear wheels of a bicycle

What is toe?

• The direction the tires are pointed relative to the vehicle center line

• The measure of the tire's centerline relative to the road surface

• The angular displacement of the steering axis from the vertical axis

• The angle between the steering axis and the vertical line

What is the effect of toe-in on a rear-wheel drive car?

• Increases tire wear

• Reduces understeer

• Increases steering effort

• Reduces oversteer

What is the effect of excessive toe settings?

• Improves steering stability

• Reduces tire wear

• Increases cornering grip

• Causes steering to be unstable
