37 11 010 Removing And Installing/Replacing Front Active Stabilizer

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 front assembly underside protection. Refer to 51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION .
Remove stabilizer link on both sides from stabilizer. Refer to STABILIZER .

IMPORTANT: Risk of damage! Pressure lines must not have any contact with the stabilizer (minimum distance 5 mm)!

Mark installation position of pressure lines to oscillating motor.

Release nuts (1, 2).

Remove pressure and vent lines from oscillating motor.

Installation:

Carry over identification to new component.

Pressure lines are protected against being mixed up by different thread diameters on the oscillating motor connection.

Tightening torque, (30 N.m.).
