Vehicle Drift/Pull Test Procedure
*NOTE
Perform road testing with no passengers (driver only) and without carrying excessive
weight.
1. Locate an acceptable road for testin which meets the followin
criteria:
1.2·-1.r
3m (9.Sft)
J,
3m (9.Sft)
Recommendations
-
Cautions
- Conduct the test on a smooth , even road without bumps or
grooves .
- Do not test on a road with excessive grade/crown .
- Conduct the test on an uncrowded road .
- Ensure there is not a strong wind present during testing.
One or more lane road .
Road is straight for at least 250m (820 ft) .
Road grade: 1.2 to 1.7 degrees maximum . The flatter the better.
Lane width: 3 to 3.5 meters (10-11 .5 feet) .
2. Before test driving , verify that all tires are OEM , correctly installed (directional tires , correct
placement for staggered sizes , etc) and set to the correct inflation pressure .
*NOTE
For the best accuracy, it is recommended to use the GDS to measure tire pressures
under Current Data within TPMS system.
3. Approach the test road section and drive through at 40 MPH. Center the steering wheel , then
slightly turn (-3 degrees) it to the left and to the right to get a feel for the steering center. Hold
the steering wheel with a light touch on center.
*NOTE
If the vehicle drives straight but the steering
wheel is off-center, it is required to perform an
alignment to correct the condition.

4. Note which direction the vehicle has a tendency to drift towards . If the vehicle tends to go left,
place the vehicle on the right side of the lane . If the vehicle tends to go right, place the vehicle
on the left side of lane, as shown .
*NOTE
To ensure accuracy, it is recommended that the test be repeated with the vehicle
travelling in the opposite direction on the same road.

5. Take time measurements to see time how long it takes for the vehicle to move from one edge
to the other edge (case 1), as shown . Use the conditions in the table below to confirm drifting
or pulling condition.

Alignment Angle Definitions
Camber Angle between the vertical axis of the wheel
and the vertical axis of the vehicle when
viewed from the front or rear.
• Positive (green line) : The upper sidewall
of the tire is tilted outwards away from the
center of the vehicle .
• Negative (red line) : The upper sidewall of
the tire is tilted towards the center of the
vehicle .
Caster
When viewing a car from the side , the angle
of the vehicle's steering axis is defined by
drawing a line through the upper and lower
ball joints (for a double wishbone front
suspension) , or through the strut tower
mount and the lower ball joint (for a
MacPherson strut front suspension).
• Positive (green line): The line leans
towards the rear of the car.
• Negative (red line) : The line leans
towards the front of the car.
Toe
The amount the tires point inwards or
outwards when viewing the car from above .
• Positive (green line) : Toe-in , the tires
point inwards towards the center of the
vehicle.
• Negative (red line) : Toe-out, the tires
point outwards away from the center of the
vehicle .

Factors that Influence Vehicle Drift/Pull
Vehicle drift or pull can be attributed to several factors. Understanding what can affect it is imperative
for anyone repairing a vehicle with a drift or pull condition.
Air pressure - Low front tire pressure can cause a vehicle to drift or pull towards that tire .
Alignment
• Camber - A vehicle will drift or pull towards the side with more positive front camber. As a rule of
thumb, the camber difference between the front tires should be less than 0.5 degrees.
• Caster - A vehicle will tend to drift or pull towards the side with less positive caster.
• 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.
• 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) .
Tires - Tires can have a significant effect on vehicle drift or pull. Arranging tires on a vehicle
according to StraightTrak can help improve a vehicle drift or pull condition. Tires contribute to vehicle
drift or pull in the following ways:
• Ply steer - Ply steer is an inherent characteristic in a tire which results in a lateral force as the tire
rolls. Rotating the tires may aid in cancelling out the effects of ply steer.
• Conicity - Tire conicity refers to the shape of the tire, and how cone-shaped it is. This can
influence vehicle drift or pull. Conicity can be present in a new tire due to manufacturing , or in a
used tire due to camber wear.
Weight - The amount of weight and where the weight is placed alters a vehicle's alignment angles,
thus changing the drift/pull tendency. It is important to consider this when diagnosing a vehicle drift or
pull.
Road Crown - Every vehicle will have a tendency to follow road crown towards the low side of the
crown.
Brake Drag - If one side of a vehicle's brakes are dragging , the vehicle can have a drift or pull
tendency towards that side . Inspect the brake system to ensure brake drag is kept to a minimum on
all four wheels.
Cross Winds - Cross winds can push a vehicle towards one side of the road . It is important to
conduct road testing by driving a vehicle in opposite directions to verify the effects of cross winds.

Proper Alignment Rack Usage and Maintenance
*NOTE
•
These tips apply to Hunter Engineering alignment racks and wheel balancers
that feature StraightTrak.
•
It is imperative that the following items be followed to ensure accurate
alignment readings.
Aligner Calibration/Maintenance Schedule - It is required that all dealer alignment racks be
calibrated by a representative every 6 months. This allows the representative to update veh icle
specs and inspect and maintain equipment.
Rolling Compensation - The rolling compensation procedure is critical to ensuring an accurate
alignment. When performing the rolling compensation , be sure to do the following :
1. Set tire pressure to factory specification .
2. Verify that the vehicle is not excessively loaded . Remove any heavy items .
3. Ensure the lift is level so vehicle 's suspension and steering are in a neutral position.
4. Set the target levels before rolling compensation. After completing the compensation , do not
re-level the targets.
Roll the vehicle by turning the left rear tire. This will
not disturb the vehicle's suspension and steering
systems.
*NOTE
Do not roll the vehicle by pushing or
pulling on body parts, bumpers, etc.
Ensure the pins are in the slip plates , and the
turnplate bridge is flush with the rolling surface to
minimize the vehicle's suspension movement.
TSB # : 13-SS-001

SUBJECT:
ALIGNMENT SPECIFICATIONS - 2013 MY
Slip Plates - The slip plates of a Hunter alignment
rack are designed to move smoothly and freely to
provide accurate measurements . Before pulling a
vehicle onto the rack , check that they move freely
and do not bind . Periodically clean the area
underneath the slip plates by blowing compressed air
through to remove any debris. If this does not free a
binding plate , contact your local Hunter
representative for cleaning and lubrication
recommendations.
StraightTrak LFM feature - StraightTrak is a
required feature for Hunter's GSP9700 wheel
balancer. This feature measures lateral force of a tire
due to ply steer, conicity, and other issues which may
contribute to vehicle drift or pull. This can be a useful
tool for vehicles with a tracking condition .
Use StraightTrak to arrange the 4 wheel/tire
assemblies of a vehicle in a configuration which will
result in the lowest drifting or pulling force by doing
the following :
1. Remove all wheel/tire assemblies from the
vehicle.
2. Balance the front left assembly on the Hunter
GSP9700 with StraightTrak feature . An icon
located in the lower right corner will show
whether or not StraightTrak is enabled.
TSB #: 13-SS-001

3. After balancing, press the tire tag button
located at the bottom right of the screen to
assign a number to that assembly. Label the
assembly accordingly with a tag or chalk mark .
Anc-mblf Placenu:nt:
4. Continue to balance and tag all four
assemblies. After all are completed , the
screen will show tire positioning and the effect
on vehicle drift/pull or vibration. The purple
horizontal arrow at the top of the screen shows
overall pulling force and direction due to tires .
The brown vertical arrows above each tire
show the RFV of each assembly.
