Torque Steer

WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

DEFINITION: On a dry, smooth, flat road, the vehicle has a left or right steering force during acceleration that is eliminated when the transmission is shifted into NEUTRAL. The level of the steering force is usually (but not always) dependent on the amount of torque which is applied by the engine.

  1. Did you review the General Description and perform the necessary inspections? If yes, go to next step. If no, see SYMPTOMS - SUSPENSION GENERAL DIAGNOSIS .
    1. Drive the vehicle on a straight, smooth, flat road.
    2. Press the accelerator and momentarily release the steering wheel.
    3. Repeat this test with the vehicle traveling in the opposite direction in order to eliminate crosswind effects. Lead/pull caused by unlevel roads and crosswinds are considered normal.
    Does the vehicle exhibit torque steer when the accelerator is pressed? If yes, go to next step. If no, system is OK.
    1. Drive the vehicle on a straight, smooth, flat road at 64-97 km/h (40-60 mph).
    2. Remove your foot from the accelerator.
    3. Shift the transmission into NEUTRAL in order to allow the vehicle to coast.
    4. Momentarily release the steering wheel and note any change in the direction of the vehicle.
    5. Repeat this test with the vehicle traveling in the opposite direction in order to eliminate crosswind effects. Lead/pull caused by unlevel roads and crosswinds are considered normal.
    Does the vehicle direction change when the steering wheel is momentarily released? If yes, go to VEHICLE LEADS/PULLS . If no, go to next step.
  4. Inspect the front suspension for worn or damaged components and repair as necessary. Did you find and correct the condition? If yes, go to step  7. If no, go to next step.
  5. Inspect the vehicle trim height. Refer to TRIM HEIGHT INSPECTION PROCEDURE . Did you find and correct the condition? If yes, go to step  7. If no, go to next step.
  6. Inspect for worn or damaged powertrain mounts. Replace as necessary. Did you complete the inspection/repair? If yes, go to next step.
  7. Operate the vehicle in order to verify the repair. Did you correct the condition? If yes, system is OK. If no, go back to step  3.
