2. Fix -oberen Achlenker-  with spring compressor VW 552  (vehicle in illustration with conventional suspension). This involves tensioning the axle strut slightly because otherwise the top ball joint can be damaged. When doing this, insert turnbuckle into the top opening of wheel housing (double panel) and in the trailing arm.

3. Using universal drive shaft/wheel hub puller from model 86 on Nr.87-1,  push (press in) peg of drive shaft approx. 20 mm - 25 mm into the wheel hub -Universal Gelenkwellen/Radnaben Abzieher-  . Make sure that the input shaft does not become kinked between the spring strut prongs. To do this, fasten a suitable wire in the bores of the spring strut prongs.
