2. Fix upper axle strut with spring compressor VW 552.  This involves tensioning the axle strut slightly because otherwise the top ball joint can be damaged. When doing this, the -Federspanner-  is pushed through the hole in the trailing arm, engaged in the upper opening of the wheel housing (double panel) and in the trailing arm and tightened with the nut. This is only necessary if the same control arm is reinstalled.
