3. INDEPENDENT FRONT
SUSPENSION JOINTS
3.1 Lower and Upper A-Arm
Ball Joint (Bonded Rubber
Bush)
3.1.1 Instructions
The assembly work may be done only by a
recognized specialised workshop. Ensure that
old and new parts do not get mixed up with
each other. It is for this reason that all the old
parts are to be scrapped immediately after a
joint has been stripped down. A complete
repair set must be used for each joint which is
repaired, i.e. use of only part of a repair set is
not permissible. All numeral or letter designa-
tions mentioned below refer to figure 12.
3.1.2 Stripping Down
Strip down the defective joint through removal
of locking ring (3), annular spacer (2) and ball
pin/bushing, assembly (1) and thereafter
clean out housing bore and locking circlip
groove.
3.1.3 Assembly
Execute assembly of the new joint parts in the
following sequence :
1. Complete moistening of the contact sur-
face between housing bore and ball pin
through application of the grease.
Note:
Apply grease, only in the case of re-
pair kit (Prévost # 611114)).
2. Insert ball pin/bushing, assembly (1). In
case of the two-bolt type, ensure that the
bolt bores are in the correct position in re-
lation to the axis of the tube.
3. Place joint in receiving fixture (C) and
mount annular assembly tool (B) on the
housing. Then locate annular spacer (2)
and locking circlip (3) in the housing using
axial load Fwith the aid of assembly matrix
(A) (For axial load, refer to table 1) (For
Prévost tools #, refer to table 2) . If the
ends of the annular spacer are not in
contact with each other, the thus formed
opening must be located at 180
to the
opening of the locking circlip. Pay attention
during assembly to ensure that the locking
circlip eyelets are located at each side of
the housing shaft axis (locking circlip eye-
let lug points to tube), and that locking cir-
clip (3) is properly engaged in the groove
of the housing.

4. When repairing defective ball pin assem-
blies, the necked down-bolt must regularly
be replaced with a new one.
In special cases where it is necessary to re-
pair defective ball pin assemblies with sealing
caps the following must be observed : Dis-
mounting of the sealing cap cannot take place
without destruction and after repair work is
complete it must be replaced with a new one.
