(25 cards)
When the upper strut mounts on a MacPherson strut vehicle are tilted forward of the upper ball joints, the vehicle has _________

What type of angle is caster?
Directional control
The imaginary line drawn through the centre of the upper and lower ball joints on a conventional steering vehicle is known as the _____________
Steering axis
Caster tends to lean the car into a turn if it is set ____________
Negative
Camber is measured by comparing the wheel angle to ____________
True vertical
If the wheel on a vehicle leans inward at the top, the angle produced is called __________
Negative camber
Excessive camber may cause _________
Tire wear
Uneven side to side camber may cause __________
The car to pull
The inward tilt of the steering axis (viewed from the front) is called _____________
Steering axis inclination
Included angle is defined as ____________
Steering axis inclination and camber
When camber is 0°, SAI and included angle will be _________
The same
Turning radius is determined by _________
The angle of the steering arms
Incorrect turning radius is determined by ___________
Tire squeal and tire wear
When measuring turning radius, if the inside wheel is turned in 20°, the outside wheel should turn ____________
Less
If the turning radius specs are not published, then __________________
Measurements should be compared side to side
The purpose of the toe angle is to __________ and ____________
Maximize tire life, compensate for any deflection in the steering linkage
When the vehicle is in motion, ideally the toe setting should be ____________
Zero (0°)
Incorrect toe setting may cause _________
Rapid tire wear
Excessive toe-out causes ______________
Scuffing wear from inside to outside
The vehicle thrust line is determined by the ___________
Rear toe
If the thrust line is off to the right of the vehicle the vehicle will ______________, _____________, and _______________
Pull to the left, pull to the side with the shortest wheelbase, dog track
The direction the vehicle will travel in is determined by the ______________
Thrust line
Moving the top of the MacPherson strut rearward will cause the ________________
Caster to move more positive
Adding a shim with the thickest portion at the top between the rear spindle and axle will cause the ______________
Camber to move more positive
