37 11 010 Removing And Installing/Replacing Front Active Stabilizer

WARNING: This page is about a different car, the 2008 BMW Alpina and 2007 BMW Alpina. 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 . See 51 47 490 REMOVING AND INSTALLING / REPLACING FRONT UNDERBODY PROTECTION .
Remove stabilizer link on both sides from stabilizer . See 31 35 005 REMOVING AND INSTALLING/REPLACING PUSH ROD (STABILIZER LINK) FOR LEFT/RIGHT 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.

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.

If necessary, remove holder with hydraulic line(s) from retaining bracket.

Release screws (1) on both sides.

Remove stabilizer from front axle carrier.

Check anti-friction bearing on both sides for damage; if necessary, replace stabilizer (observe note at start of repair instruction).
