Factors that Influence Vehicle Tracking
Vehicle drift or pull can be attributed to several factors. Understanding what can affect it is imperative for anyone repairing a vehicle with a tracking condition.
Air pressure - Low front tire pressure can cause a vehicle to track towards that tire.
Alignment
Camber - A vehicle will track towards the side with more positive front camber.
Caster - A vehicle will tend to track 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 significant effect on vehicle tracking. Arranging tires on a vehicle according to
StraightTrak can greatly improve or eliminate a vehicle tracking condition. Tires contribute to vehicle tracking 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 tracking. 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 tracking tendency. It is important to consider this when diagnosing a vehicle tracking condition.

SONATA (YF) VEHICLE TRACKING DIAGNOSIS AND REPAIR 16” AND 17”
SUBJECT: WHEEL VEHICLES ONLY (SERVICE CAMPAIGN 928)
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 tracking 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 vehicle 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:
Set tire pressure to factory specification.
Verify that the vehicle is not excessively loaded. Remove any heavy items.
Ensure the lift is level so vehicle’s suspension and steering are in a neutral position.
Set the target levels before rolling compensation. After completing the compensation, do not relevel 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.

SUBJECT VEHICLES ONLY (SERVICE CAMPAIGN 928)
Ensure the pins are in the slip plates, and the turnplate bridge is flush with the rolling surface to minimize the vehic le’s suspension movement.
Slip Plates - The slip plates of a Hunter alignment rack are designed to move smoothly and freely to provide accurate measurements. Before driving 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 an optional 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 tracking. This is a very useful tool for vehicles with a tracking condition.

SUBJECT: WHEEL VEHICLES ONLY (SERVICE CAMPAIGN 928)
Use StraightTrak to arrange the 4 wheel/tire assemblies of a vehicle in a configuration which will result in the least tire pull 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.
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.
4. Continue to balance and tag all four assemblies. After all are completed, the screen will show tire positioning and the effect on tire 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.
Select “Show Least Pull” for lowest
tire effects on pulling.
Select “Show Least Vibration” for the smoothest ride.

Cross camber change (left camber minus right camber)
0.5° ~ 1.0°
4 ~ 6 seconds 0.0° ~ 0.5°
IMPORTANT
The suggested cross camber adjustment values listed in the table are based on the results of Case #1, 40 MPH road testing.
The values listed in the table are for cross-camber change, not absolute cross camber.
The cross camber value is to be achieved by adjusting the left and right camber values, staying within the individual camber specification tolerance range (
-0.5° ± 0.5°
).
For vehicles which track right, adjust the cross camber value more positive.
For vehicles which track left, adjust the cross camber value more negative.
Some vehicles may need additional adjustment beyond the suggested range to pass the road test.
Tighten both nuts (top and bottom) when the desired camber is achieved.

SERVICE CAMPAIGN NOTIFICATION
Dear 2011 or 2012 Sonata Owner:
A small number of owners of 2011 and 2012 Sonata vehicles equipped with factory-installed 16-inch or 17-inch wheels and tires may have experienced dissatisfaction with vehicle tracking. Hyundai has issued a service campaign to correct this condition on those vehicles that may be affected. This letter provides you with information about the service campaign.
What is the purpose of the service campaign?
Some 2011 and 2012 Sonata vehicles equipped with factory-installed 16-inch or 17-inch wheels and tires may not track as the driver desires without slight/minor steering wheel correction when driving on straight, flat roads.
Hyundai has developed a service procedure to improve the tracking of vehicles affected by this condition.
What vehicles does this apply to?
This service campaign applies only to 2011 and 2012 model year Sonatas equipped with factory-installed 16-inch and 17-inch wheels and tires that were manufactured beginning on May 1, 2011 through July 31, 2011 and that do not track straight without steering wheel correction on straight, flat roads. If your vehicle tracks straight, you do not need to have this service campaign performed.
What will Hyundai do?
If your vehicle does not track as you desire on straight, flat roads, your
Hyundai dealer will check your vehicle’s wheel alignment and how your vehicle tracks. If necessary, your Hyundai dealer will install new front suspension struts and/or camber bolts, update the Electronic Power Steering software, and perform a wheel alignment procedure at no charge to you.
What should you do?
Please schedule an appointment at your convenience to take your vehicle to your Hyundai dealer. When you make an appointment, please confirm the dealer’s schedule to determine how much time will be required to perform the work so you may plan appropriately. It may be necessary to leave your vehicle at the dealer overnight.
To help facilitate the process, you can schedule an online appointment.
Please vis it Hyundai.com, click on “Find a Dealer” and input your zip code.
When your preferred dealer appears, click on “Schedule Service” under their address.
