WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2006 BMW 760i, 2006 BMW 760Li, 2005 BMW 760i, 2005 BMW 760Li, and 2004 BMW 760Li. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system. Seal off pipe connections with plugs.
NOTE:
A light film of grease on the anti-friction bearing in no way impairs the operational capability of the stabilizer. In a warranty case you must always provide a fault memory printout, even where there is no fault memory entry, with the defective part.
Necessary Preliminary Tasks:
- Remove complete rear axle carrier. Refer to AXLE CARRIER .
IMPORTANT:
To prevent the stabilizer from being distorted, secure first the left retaining bracket (without
elongated holes) and then the right retaining bracket (with
elongated holes) to the front axle carrier.
Release screws (1) on both sides.
Check anti-friction bearing on both sides for damage; if necessary, replace stabilizer (observe note at start of repair instruction).
Installation:
Check rubber mount on both sides, replace if necessary. Refer to AXLE CARRIER RUBBER MOUNTS .
Tightening torque, (60 N.m.).
IMPORTANT:
Risk of damage! Pressure lines must not have any contact with the stabilizer (minimum distance 5 mm)!
Carefully raise stabilizer (2) with a lever (1) until screw (3) is accessible.
Release nuts (3, 4).
Installation:
Pressure lines are protected against being mixed up by different thread diameters on the oscillating motor connection.
Tightening torque, (30 N.m.).
