Adjusting Front-Axle Toe

  1. Before adjusting the toe, check whether the steering wheel is offset with respect to the steering gear. Reposition the steering wheel if necessary.

    To do this, perform the following steps:

    1. 1.1. Move steering gear to center position.
    2. 1.2. Turn wheels to the straight-ahead position.
    3. 1.3. Then, adjust the front wheel alignment if necessary until the center position marking -1-  is aligned with the arrow.
      1. Centre position marking
      2. Desired breaking point of retaining pin in new steering gears

      If the front underbody panelling is fitted, the position of the center position marking can be checked using a mirror.

  3. With the steering wheel in center position, adjust the toe at the relevant tie rod.
    1. 3.1. Loosen the lock nut -2-  . To do this, counter at the tie-rod ball -3-  using a suitable open-ended wrench.

      Then, with the steering wheel in center position, adjust the toe at the hexagon -1-  on the tie rod(s) using a suitable open-ended wrench.

      Then tighten the lock nut (on the relevant tie rod) to the specified tightening torque.

    2. 3.2. To loosen and tighten the lock nut, use socket-wrench insert 9730 -A-  together with a torque wrench -B-  .

      The tightening torque for the lock nut of 50 Nm (37 ftlb.), when using socket-wrench insert 9730 -A-  , corresponds to a value of approx. 32.5 Nm (24 ftlb.) on the torque wrench.
