a. Camber - A vehicle will drift or pull towards the side with more positive front camber. Camber
difference between the front tires greater than 0.5
degrees can lead to a drift pull concern.
b. Caster - A vehicle will drift or pull towards the side with the least positive caster.
c. Steering Axis Inclination (SAI) - The angle formed by the line drawn through the steering pivot
axis and a line at true vertical when viewed from
the front of the vehicle. SAI is designed into a vehicle's suspension and aids straight-line stability.
This angle can be measured by the alignment machine. For Hunter units, it is measured during the
caster sweep process. It is useful for checking for damaged components when the SAI difference
between left and right sides is more than 1 degree. If SAI is lower on one side of the vehicle it may
indicate a bent lower control arm. If SAI is higher on one side of the vehicle it may indicate damage
to the upper strut mount.
d. Thrust angle - This is the direction the rear axle is pointing as a result of the rear toe angles and
results in the steering wheel being off-center. To
avoid this situation, rear camber and toe should be adjusted before the front when performing a
four wheel alignment. After the rear is set, center the steering wheel, lock it in place, then adjust the
front camber, caster, and toe (if applicable).
3. Tires - Tires can have significant effect on vehicle drift or pull for the following reasons:
