Pre-load comparator (1) by approximately 4 mm and reset
it by suitable lever (4), lift upper swinging arm (3) as much
as possible and detect the displacement of comparator (1)
hand corresponding to the clearance of articulated head (2).
If detected value is between 1.5 and 2.0 mm, the articulated
head (2) needs to be replaced, as described in relating
chapter.
Position comparator (1) tracer point with magnetic base
99395684 on the top of the articulated head of lower
swinging arm (2).
By suitable lever, lower swinging arm (2) and reset
comparator (1).
By suitable pliers (2) applied on articulated head (3) and on
lower swinging arm (1), apply strong pressure on head and
arm and write down comparator (4) hand displacement
corresponding to articulated head clearance.
If detected value is between 1.5 and 2.0 mm, the swinging arm
needs to be replaced, as described in relating chapter.
Remount dismounted parts in order to make checks.
Check the clearance of lower swinging arm
articulated head
See Figure 26: the nut for screw (3) to secure tie rod
(2) to lower swinging arm (1) and see Figure 25: the
nut (4) for the screw to secure lower swinging arm
(2) to cross member (3): they must be tightened at
prescribed torque with the vehicle lowered and
vehicle empty weight weighing down on suspension.

TIE RODS
Remove the stabilizer bar as described under the relevant
heading (operation 528030).
Take out the nut for the screw (2) securing the tie rod (3)
to the bottom suspension arm (1) and remove the screw (2)
from this.
Take out the nut securing the link pin (5) to the mounting (4).
Using the extractor 99347060, remove the swivel head (5)
from the mounting (4).
Take out the nut (3) for the screw (4) securing the tie rod
(1) to the top suspension arm (2) and remove the screw (4)
from this. Take out the nut securing the link pin (5) to the
mounting (7). Using the extractor 99347074 (6), remove the
swivel head (5) from the mounting (7). Remove the screw
stay (1) from the vehicle.
Loosen the nut (2) and unscrew the swivel head (1) from the
top tie rod (3).
Screw the new swivel head (1) onto the tie rod (3)
positioning it at the values shown in the figure.
Removal
If removing the mounting (7), so as not to change the
wheel geometry, not the number and thickness of
the spacers (if there are any) under the mounting to
mount them in the same way when refitting the
mounting (7).

OVERHAULING THE SUSPENSION
Refit the top tie rod (5) to the top suspension arm (3) and
to the mounting (6).
Tighten the nut securing the link pin (1) to the required
torque.
Refitting
The nut (4) for the screw securing the tie rod (5) to
the lever (3) must be tightened when the load of the
empty vehicle weighs on the suspension.

Refit the bottom tie rod (3) to the bottom suspension arm
(1) and to the mounting (4).
Tighten the nut securing the link pin (5) to the required
torque.

At the end of the re-fitting check the wheels
geometry as described in the relevant paragraph.
Then tighten the nuts, which fasten the articulated
head to the relevant tie-rods, to the prescribed
torque.
The nut (2) for the screw securing the tie rod (3) to
the bottom lever must be tightened when the load
of the empty vehicle weighs on the suspension.
Re-fit the stabilizer bar.

Removal
Remove the lower and upper tie-rods as described in the
relevant paragraph (operation 500761) and go on as follows:
Figure 40
Loosen the nut (2) and unscrew the threaded pin (1) until
the torsion bar (3) is fully ”unloaded”.
Take out the nuts (4) for the screws securing the mounting
(5) to the chassis frame.
Remove the mounting (5) from the torsion bar (3).
Remove the nuts securing the link pins (1) from the top (4)
and bottom (6) suspension arms to the stub axle (5).
Support in an appropriate way the steering knuckle (5)
together with brake caliper and wheel hub and with the tool
No. 99347074 (2) remove the steering knuckle (5) from the
levers (4 and 6).
Place the steering knuckle (5) on a support without straining
