Information 

• The bearing is replaced using the assembly fixture T10230. 
• Pressure head no. 13 is used from the selection of attachments T10205. 

1. Release brake calliper and hang at a suitable position in the wheel housing → WM 474119 REMOVING AND INSTALLING REAR BRAKE CALLIPER . Do not open the brake system.

7. The pressure piece must be positioned correctly on the contact surfaces of the wheel bearing housing. The cut-out in the pressure piece -arrow-  should be used as a viewing window. Now press the bearing out carefully. When doing so, stand to the side of the tubular piston cylinder and make sure that the tubular piston cylinder cannot fall down.

Information 

• The entire threaded parts of the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on the wheels, or the wheel suspension is raised using a universal vehicle lift. Dimension -X- from lower edge of wing to middle of axle 506 mm ±10 mm corresponds to vehicle position.

• Screws and nuts are Dacromet-coated and must not be greased. 
• Use new screws and lock nuts. 
• Observe tightening torques →  WM 4200TW TIGHTENING TORQUES FOR REAR AXLE   . 

1. To fit the new bearing use the -Druckstucke-  and tubular cylinder VAS 6178. No. 13 is screwed into the tubular piston cylinder. No. 2 is screwed on to the threaded rod and positioned in No. 13 for pressing in the bearing.

3. The pressure piece must be positioned correctly on the sealing surfaces of the wheel bearing housing. Now press the bearing in carefully. When doing so, stand to the side of the tubular piston cylinder and make sure that the tubular piston cylinder cannot fall down. Maximum assembling force must not exceed 30 KN at the stop.

   Press the bearing in until it is enclosed evenly by the rubber lip.

4. If the bearing for the axle strut is fitted cleanly, install the wheel bearing housing in the bottom axle strut.
