What the manufacturer’s document says

12-03-10-002 ・ fault and correction ・ for GM vehicles in general

Applies to

  • Applies to 2006-2013 GM passenger cars and light duty trucks.

    the passage
    2006-2013 GM Passenger Cars and Light Duty Trucks

Fault

  • Vibration may be felt in the steering wheel or seat, centered at 10-14 Hz, between 93-115 km/h (58-72 mph).

    the passage
    Some customer may report vibration in the steering wheel or the seat centered at a frequency of 10-14 Hz, between 93-115 km/h (58-72 mph).

Finding the cause

Possible causes

  • Inappropriate wheel torque methods may leave the wheel and tire assembly offset when mounted.

    the passage
    Inappropriate wheel torque methods may cause the wheel and tire assembly to be offset when mounting.

Correction

Repair

  1. Remove the tire and wheel assemblies, index them at least two stud positions from the previous position, and re-install them.

    the passage
    Index them at least two stud positions from the previous position and re-install them.

  2. Step 1: with the wheel off the ground, install all lug nuts hand tight using only a socket.

    the passage
    With the wheel off of the ground, install all lug nuts hand tight using only a socket.

  3. Step 2: snug all lug nuts in a star or criss-cross pattern with a hand wrench.

    the passage
    Snug all lug nuts using a star or "criss-cross" pattern using a hand wrench.

  4. Step 3: lower the vehicle until there is just enough contact to resist, then torque to specification with a torque wrench.

    the passage
    Lower the vehicle until there is just enough contact to provide resistance to complete torquing to specification with a torque wrench.

Caution

  • This first order tire/wheel vibration may be misdiagnosed as assembly imbalance or excessive tire Radial Force Variation.

    the passage
    wheel vibration may be misdiagnosed as tire/wheel assembly imbalance or excessive tire Radial Force Variation.

  • Improper torque may distort the brake rotor and vary the wheel mounting, which can cause smooth road shake.

    the passage
    Improper torque may cause distortion of the brake rotor, and may result in variance in wheel mounting that can cause smooth road shake vibration.

  • Do not use torque sticks or an impact driver to tighten wheel lug nuts.

    the passage
    Do not use torque sticks or an impact driver to tighten wheel lug nuts.
