When installing the spring strut, make sure that the spring strut fastening screw - on the wheel carrier - is tightened only in vehicle position. Vehicle position means: Vehicle standing on the wheels, or the wheel suspension is being raised with a universal lift.
NOTE:
Only optimized axle nuts - version B - for drive shaft fastening are available from the Parts Service. These two-part fastening nuts (M22) have a moveable washer (arrows). Retrofitting is possible for all 911 Carrera (996) vehicles and for all Boxsters.
