Earlier (older model) vehicles:

• often used wide tread, small diameter tires

• often used wide tread, large diameter tires

• often used narrow tread, large diameter tires

• None of the answers listed

_______, sometimes referred to as trim height, is the amount of distance between the ground and a specified part of the vehicle, such as the fender wall, upper control arm, or rocker panel.

• Setback

• Thrust line

• Ride height

• Ackermann angle

Which of the following statements is correct?

• Most front-wheel drive vehicles use a positive scrub radius

• Scrub radius is a measure of how small a circle the vehicle can turn in when the steering wheel is turned to the limit

• Ideally, the thrust line and the vehicle's geometric centerline should line up closely

• A setback issue in the rear will pull toward the side with the maximum setback

The ________ is a geometric alignment of linkages in a vehicle's steering such that the wheels on the inside of a turn are able to move in a different circle radius than the wheels on the outside.

• Watt's linkage

• Scrub radius

• Included angle

• Ackermann principle

• Horizontal

• Vertical

• Inside

• Outside

Toe-out on turns is an adjustable alignment angle.

• True

Tech A says setback is not adjustable. Tech B says setback can cause a pull on a front-wheel-drive car. Who is correct?

• Tech A

• Tech B

• Both Techs A and B

• Neither Tech A nor B

Vehicle alignments should be performed when tire wear shows any tire wearing angle issue.

• True

• False

If the camber angle is specified as negative, then it is added to the SAI angle.

• True
