Fix upper trailing arm -inset 1- 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.
