Sentra Sedan L4-1597cc 1.6L SOHC (E16S) (1986)
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 more than allowable (see example in Figure 2) when driving straight ahead on a straight flat road.
Allowable specifications for steering wheel off-center
^ All Nissan (except NV1500, 2500, and 3500): 2 mm or less.
^ NV1500, 2500, and 3500: 4 mm or less.
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.
^ A vehicle is said to "pull" if it completes a lane change in less than 7 seconds (with no steering correction from the driver) when driving at 60 MPH on
a road with less than 2 degrees of road crown slope. All four wheels must pass into the other lane during this time (7 seconds).
