with code U55 (Multi-link axle)

Removal

1

Cut off rubber tabs (5) using suitable means from elastomer bearing (2).

 This makes it easier to position thrust piece (081) and thrust piece (082) and to press out the elastomer bearing (2).

2

Bolt the  hollow piston cylinder (010) to  retaining plate with security belt (4) to the counterholder (02) and position on rear axle carrier (1).

 Secure  hollow piston cylinder (010) with  retaining plate and security belt (4) on rear axle carrier (1).

 The  pull-off device and insertion device includes the thrust piece (081), thrust piece (082), thrust piece (083), counterholder (02), counterholder (05), spindle (03) and spindle head (07).

 The security belt consists of a  retaining plate with security belt (4).

3

Insert spindle (03) with spindle head (07) through  hollow piston cylinder (010),  retaining plate with security belt (4) and the counterholder (02).

4

Position thrust piece (082) onto spindle (03), screw on spindle head (07) and position on elastomer bearing (2).

5

 Mount hydraulic hose and  hand pump onto  hollow piston cylinder (010).

6

 Pre-tension and align pull-off device.

 Mount spindle head (07) by hand.

7

Press elastomer bearing (2) far enough forward until the thrust piece (082) makes slight contact with the edge in the bushing of the rear axle carrier (1).

 Thrust piece (082) may not press onto rear axle carrier (1).
Otherwise, the contact surfaces of the rear axle carrier (1) may be damaged.

8

 Relieve pull-off device.

9

Unscrew spindle head (07) and remove thrust piece (082) from spindle (03).

10

Position thrust piece (081) onto spindle (03), screw on thrust piece (083) and spindle head (07) and mount onto elastomer bearing (2).

 Mount spindle head (07) by hand.

11

 Pre-tension and align pull-off device.

12

Press elastomer bearing (2) out of rear axle carrier (1).

13

 Remove pull-off device,  retaining plate with security belt (4) and  hollow-piston cylinder (010).

Installation

14

Clean insertion surfaces on rear axle carrier (1).

 The insertion surfaces on the rear axle carrier (1) must be absolutely free of dust and grease.
Otherwise, faults may occur when pressing in the elastomer bearing (2).

15

Bolt on  hollow piston cylinder (010),  retaining plate with security belt (4) and counterholder (04).

16

Position and align elastomer bearing (2) on rear axle carrier (1).

 Move elastomer bearing (2) into correct position.
Otherwise, the elastomer bearing (2) will be damaged when pressing in.

 Direction of arrow (arrow A) on elastomer bearing (2) relative to direction of travel. The marking (arrow C) on the elastomer bearing (2) must line up with the cutout (arrow D) on the rear axle carrier (1).

 Press-in elastomer bearing (2) without insertion agent.

17

Insert spindle (03) with spindle head (07) through  hollow piston cylinder (010),  retaining plate with security belt (4), counterholder (05), rear-axle bushing and the elastomer bearing (2).

 Secure  hollow piston cylinder (010) with  retaining plate with security belt (4) on rear axle carrier (1).

18

 Pre-tension and align insertion device.

 Mount spindle head (07) by hand.

19

 Mount hydraulic hose and  hand pump onto  hollow piston cylinder (010).

20

Press in elastomer bearing (2) up to end stop in rear axle carrier (1).

21

 Remove insertion device,  retaining plate with security belt (4) and the  hollow piston cylinder (010).
