PURPOSE:
This bulletin provides information on the diagnosis of steering pull, torque steer, and wander conditions. This information is also in the "1995 Chassis Service Manual."

For both steering pull and torque steer conditions, a series of tire rotations must be performed, in their entirety, to ensure that one or more tires are not the cause of the vehicle's steering pull or torque steer. All possibilities of a tire related lead or pull must be eliminated before any wheel alignment adjustments are made.

If a steering pull, torque steer or wander condition is present, use the "Road Test Chart" in this bulletin to determine which condition exists.
