ALIGNMENT AND ROAD CROWNAPPLIED VEHICLES: All InfinitiSERVICE INFORMATIONCustomers may report that their vehicle “pulls” or the steering wheel is “off-center”. This bulletin discussesthese subjects and provides diagnostic and repair information.If a vehicle drifts to one side of the road, it may be the normal result of road crown. Most roads in the UnitedStates are built with a “crown” to help rain water drain from the road surface. The slope of the road crownvaries from place to place. In most cases the crown slopes 2 to 3 degrees to the right.Vehicles have a natural tendency to drift to the low side of the crown. The greater the slope of the crown, thefaster 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 theeffect of a highly crowned road.Some freeways slope to both the left and right from the center. When driving on a freeway that slops in bothdirections, a vehicle may exhibit a small amount of drift to the left when driving in the left lane and a smallamount 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 thecustomer may incorrectly perceive them to be. Use the information provided in this bulletin to identify andrepair other types of "vehicle pull".Incident Description:PullThe vehicle consistently drifts to one side while driving at a constant speed on a straight, flat road.• A vehicle is said to “pull” if it completes a lane change in less than 7 seconds (with no steeringcorrection from the driver) when driving at 60 MPH on a road with less than 2 degrees road crownslope. All four wheels must pass into the other lane during this time (7 seconds).
