Maintenance of the front spring suspension comes to
checking and tighting the joints of longitudinal lever, tie-rod and
transverse stabilizer. Knocks and squeaks in the joints are the
symptoms of worn-out joints. Remedy these troubles by replac-
ing these joints. In the service period, do not allow a deformation
of the tie-rod and steering linkage. When replacing the joints,
carry out the last tightening of nuts on the automobile standing
on the wheels.
Never operate the automobile provided with the spring suspen-
sion when the shock absorber is faulty or when there is no shock
absorber on the automobile.
Maintenance of the shock absorbers consists in periodically
checking them for tightness and reliable fastening, as well as in
changing the fluid in compliance with the instructions laid down
in Lubrication Table.
If leakage of fluid through the rod seal and the reservoir
sealing rings is detected, tighten nut 18 (Fig. 55). If the leakage
fails to be eliminated, repair the shock absorber in a workshop.
