WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2008 BMW 760Li, 2007 BMW 760Li, 2006 BMW 760i, 2006 BMW 760Li, and 2005 BMW 760i. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Observe safety instructions for raising the vehicle!  See 00..... LIFTING VEHICLE WITH A LIFTING PLATFORM
NOTE: If during removal operations the guide arm is detached from the rear axle carrier, it is necessary after reinstallation to carry out a wheel/chassis alignment check.
IMPORTANT: The guide arm to wheel carrier connection has been changed from a conical seat to a ball seat! Spare parts are offered for both variants.

To ensure a correct bolt connection, check before installing the guide arm whether the seat for the guide arm matches the seat for the wheel carrier.
