BMW 7 Series: Removing And Installing Electric Steering Box (EPS)
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 part.
Necessary preliminary work:
- Disconnect BATTERY EARTH LEAD
NOTE: High-current-carrying wiring laid with permanent positive connection (80 A fuse).
- Remove underbody protection at FRONT and REAR
- Remove COVER FOR STEERING ASSEMBLIES on left and right
- Remove stiffening plate
- Remove TRACK ROD END on both sides from swivel bearing
- Remove LOWER SECTION of steering shaft from steering box
- Version with Dynamic Drive:
- Remove ANTI-ROLL BAR LINK ON RIGHT OF ANTI-ROLL BAR
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.
