  1. Remove bolts (1, 2).
  2. Loosen front bolts (3).
  3. Measure suspension strut tower (A) at measuring point (4), assess and enter measurement value as well as result into check list. Model 238.3

    NOTESAlways  replace spring strut dome (A) in event of cracks, folds or deformation.

    Otherwise the required minimum strength of the structural components is not ensured.

    IMPORTANT Measuring points (4) is always the bolt head when the strut is installed.

    IMPORTANT Reshaping or repairing not  permissible.

  4. Measure connecting flange on suspension strut tower for front module carrier (B) at measuring point (5) from bottom, assess and enter measurement value as well as result into check list. Model 238.3

    NOTES In event of cracks or folds on the connecting flange on the suspension strut tower for the front module carrier (B) always  suspension strut tower.

    Otherwise the required minimum strength of the structural components is not ensured.

    IMPORTANT Measuring point (5) is always the center thread on the connection flange of the suspension strut tower for the front module carrier (B).

    IMPORTANT Reshaping or repairing is only permissible to a limited extent  .
