Information 

• All screws and bolts on the axle must be tightened in vehicle position. Vehicle position means: vehicle resting on its wheels, or the wheel suspension is raised with a universal vehicle lift. Dimension -X- , from lower edge of wing to centre of wheel → Control value: 502 mm+/-10 mm corresponds to vehicle position.

• Carry out a visual inspection of all parts. 
• Replace self-locking nuts. 
• Replace all expansion screws (screws fitted using torque angle tightening procedure). 
• Observe correct tightening torques and torque angle → Tightening torques for front axle. 
• Make sure the bevel pinions from the ball joints are clean. Clean with a lint-free cloth if necessary. Do not use cleaning agent. 

1. Carefully insert the spring strut and tighten to mounting saddle (four M8 fastening nuts) with the prescribed tightening torque.
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 spring compressor VW 552  → see Fig 3 is engaged in the upper opening of the wheel housing (double panel) and in the axle strut and pre-tensioned with the nut.

3. For easy fitting, slightly raise the wheel carrier using a suitable lift so that the upper ball pin can be inserted. Use a suitable lift with rubber base → see Fig 4 in order to prevent slipping.
