RISK OF INJURY if oil comes into contact with eyes and skin!

IMPORTANT: Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Close off pipe connections with plugs.

NOTE: A film of grease on the anti-friction bearing in no way impairs the operational capability of the stabilizer.
In all warranty cases you must always provide a fault memory printout, even where there is no fault memory entry, with the defective part.

Spring-type actuator only installed on E70!

When converting the front axle stabilizer with spring-type actuator (1) to front axle stabilizer with dual piston (2), it is necessary to perform a RECODING !
