32 13 075 Removing and installing electrical steering box active steering: Notes

IMPORTANT: Steering box: 
Check connection of steering box for corrosion, clean contacts if necessary. The steering box must be replaced if the corrosion is too far advanced.
Connecting line: 
In the event of moisture/corrosion inside the two plug connections, check the insulation of the connecting line. If the insulation reveals any noticeable/striking features, partial replacement will be necessary. Otherwise it will be sufficient to replace the contacts or connector housing.
NOTE: In a warranty case you must always provide a fault memory printout, even where there is no fault entry, with the defective component.

Necessary preliminary tasks: 

IMPORTANT: To avoid the need for axle/wheel alignment, mark position of steering box (1) to front axle support (2).
To do so, draw a wide white stripe on the front bolting points (left and right) and apply a thin black marking (3) to this stripe.

For greater clarity steering box shown removed.
