校正代码 32010112 1.86 NOTE: Unless otherwise explicitly stated in the procedure, the correction code and its associated FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so. NOTE: See Flat Rate Times to learn more about FRTs and how they are created. NOTE: See 人员保护 to make sure wearing proper PPE when performing the below procedure. NOTE: See 人体工程学注意事项 for safe and healthy working practices.

拆卸

  1. Remove the front subframe. See 副框架总成 - 前 (RWD)（拆卸和安装）.
  2. Remove the outer bolts that attach the steering gear assembly to the front subframe.
  3. Remove the inner bolts that attach the steering gear assembly to the front subframe.
  4. Remove the steering gear assembly from the front subframe.

安装

  1. Position the new steering gear assembly onto the front subframe for installation.
  2. Loosely install the inner bolts that attach the steering gear assembly to front subframe.
    注
    2x bolts, 18mm, 75 Nm. Torque at a later step.
  3. Install the outer bolts that attach the steering gear assembly to the front subframe. For older M3 vehicles with 13 mm bolts:
