M37x AWD V6-3.7L (VQ37VHR) (2012)
Customers may report that their vehicle's steering wheel is "Off-center" because the steering wheel spokes are tilted to the left or right when the vehicle
continues straight ahead on a straight flat road (see example in Figure 1).
If a vehicle's steering wheel spokes are slightly off center while driving straight it may be the normal result of road crown. Most roads in the United
States are built with a "crown" to help rain water drain from the road surface. The slope of the road crown varies from place to place.
Vehicles have a natural tendency to drift to the low side of the crown. The greater the slope of the crown the faster the vehicle will drift in that direction.
Tires and vehicles are designed to counteract the effect of typical road crown but may not fully counteract the effect of a highly crowned road.
Some freeways slope to both the left and right from the center. When driving on a freeway that slopes in both directions a vehicle may exhibit a small
amount of drift to the left when driving in the left lane and a small amount of drift to the right when driving in the right lane.
This bulletin does not address road crown issues because they are not vehicle related, although the customer may incorrectly perceive them to be.
Description/Definition of Steering Wheel "Off-center" Condition
The steering wheel spokes are tilted to the left or right 2 mm or more (see example in Figure 2) when driving straight ahead on a straight flat road.
^ When driving straight on a highly crowned road the steering wheel may be turned (off-center) to counteract the affect of the road crown. When road
testing for an off-center condition the vehicle should be driven on a straight flat road.
^ Although the vehicle does not pull in either direction the customer may perceive that the vehicle pulls because it will respond if he or she tries to bring
the steering wheel back to center. This condition can occur if the tie rod length is uneven (not adjusted correctly) from side to side.
Description/Definition of a Vehicle "Pull" Condition
The vehicle consistently drifts to one side while driving at a constant speed on a straight flat road.
