Technical values






Preliminary work

Remove the wheel. -> 440519 Removing and installing wheel - section on "Removing" Removal and Replacement

Tools

Trailing arm tools










Removing lower axle strut

Removing lower trailing arm





CAUTION

Increased risk of accidents if the wheel carrier is raised improperly.

- Injuries and material damage are possible.

-> Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).
-> When raising the suspension, use a suitable intermediate layer (hard rubber).
-> Do not damage the brake cover plate.

1. Unscrew plastic nuts -arrows- on front wheel housing liner.





2. Fix upper axle strut -Inset 1- with spring compressor VW 552. This involves tensioning axle strut slightly because top ball joint can otherwise get damaged. When doing this, the -Spring compressor- is pushed through the hole in the axle strut, engaged in the upper opening of the wheel well (double panel) and in the axle strut and tightened with the nut.





3. Loosen the fastening nuts => see figure from the bottom ball joint and press off with the press-out tool T10187. When doing this, leave fastening nut flush on ball journal, so as not to damage thread.





4. Remove the lower fastening screw of the spring strut -arrow-. For this purpose, lift wheel carrier with a suitable lift -Lift with a rubber base- (to prevent slipping) to the extent that the screw -arrow- can be unscrewed easily.





5. Mark eccentric screws -arrow- for adjusting camber and caster on subframe (facilitates fitting when reinstalling).





6. Then remove eccentric screws. When doing so, ensure that joint boot is not damaged by eccentric -arrow-. Pull (press) axle strut out of the subframe mounting points -A-.





7. Remove fastening nut -Inset 5- from ball joint. Tilt -trailing arm- down all the way and pull ball joint carefully out of the wheel carrier.

1. Install in reverse order.

Information

- The entire threaded parts of the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on the wheels, or the wheel suspension is being raised with a universal vehicle lift. -Dimension X- , from => Control value: 502 mm+/-10 mm corresponds to the vehicle position.





- Visually inspect all parts.

- Replace self-locking nuts.

- Replace all expansion screws (screws which are fitted with torque angle tightening procedure).

- Use correct tightening torques and torque angle.

Use an intermediate layer (hard rubber). Do not damage the brake cover plate.





Screws are Dacromet-coated and must not be greased.
