Loosen screws (1, 2, 3).
Measure, evaluate suspension strut tower (A) at measuring point (4) and enter measurement value as well as result in checklist.
Always replace spring strut dome (A) in event of cracks, folds or deformation.

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

Measuring point (4) is always the screw head in the case of an installed strut.

A reshaping or repair is not permissible.

Measure, evaluate connecting flange at suspension strut tower for front module carrier (B) at measuring point (5) and enter measurement value as well as result in checklist.
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.

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

Reshaping or repairing is permissible to a limited extent.
