TIGHTENING MOMENTS (daNm)
Disconnect the battery.
Loosen the front wheels screws.
Lift the vehicle by means of a two-column elevator.
Dismount the front wheels.
DISMOUNTING
In the engine compartment:
Cut the rubber bellows maintaining clip and push it towards cowl panel.
By means of the PF 476 device, depress the ball joints of the steering rods funnel from the
steering knuckle.
Dismount:
- connection screw between the cardan joint of the steering column lower shaft and the
steering rack gear shaft;
- steering box attachment screws on the crossbeam.
Detach the steering box assembled with the steering rods.
REMOUNTING
Perform the dismounting operations in the reverse order, observing the required tightening
moments.
In case a new steering box is mounted, the parallelism is obligatory to be adjusted, observing
the parallelism adjusting procedure described in chapter 31.

Steering box pusher
ADJUSTMENT
When a noise is found in the area of the
steering box pusher, it is obligatory to per-
form its correct adjustment.
1. Noise identification (clattering).
Hold by hand the rack in pusher’s side and
check the transversal clearance (up-down). A
noise in the pusher’s area might occur while driv-
ing, caused by a clearance followed by a noise
(clattering).
If the clearance at the pusher is bigger than
0.31 mm, adjust the clearance and/or dismount
the steering box and eliminate the cause.
2. Checking and adjustment of the
pusher’s clearance.
The pusher adjustment is to be performed tak-
ing into consideration both the rack wear and the
pusher’s wear:
- bring the rack in the minimum radial
runout position;
- position the feeler of a comparative
gauge on the cylindrical part of the rack ( oppo-
site to the threaded part) in the area of rack exit
from casing ( gear side);
- rotate the gear on the whole rack length
and establish the minimal runout point, where the
value read on the gauge is minimal;
- adjust the comparing gauge to zero;
- by means of a 17 mm fixed wrench,
rotate the rack from the opposite end until the
pusher is in contact with the threaded plug( a
higher wrench effort may be noticed for a re-
duced movement red on the comparing gauge);
- read the value shown by the comparing
gauge which must be smaller than 0.31 mm.
The pusher clearance adjustment is performed in
the minimal runout point by rotating the threaded
plug (4) to a moment of 1± 0.2 daNm and un-
screwing ˘ rotations, then secure it by bead-
ing (caulking) in “S” area.
When mounting, put 23 ± 5 cm
3
grease
UM 185 Li2M for : rack, gear, sealing ring
and pusher’s spring, inner surface of the
threaded plug.
Check the operation and check also during
driving if the steering wheel is returning at the
straight line driving position (steering central
point).
1. Pusher
2. “O” ring
3. Spring
4. Threaded plug

Noise absorbant bushing
DISMOUNTING
Loosen the screws of the right front wheel.
Lift the vehicle by means of a two-column elevator.
Dismount the right front wheel.
Dismount :
-steering box casing protection bellows-left steering rod end;
-the right steering connected rod.
Rotate the steering wheel to the right (complete turn), the rack is withdrawing towards left.
Remove, by means of a screwdriver the used noise absorber bearing.
REMOUNTING
Carefully clean the rack and the noise absorber bearing seat and grease with special grease
containing MoS2 and then mount the new noise absorber bearing.
Position the pins (A) in their casing seats.
Rotate the steering wheel to the left until the rack stands out the bearing.
Remount on the rack:
- the steering connecting rod (safety washer and limiter washer are to be obligatory
positioned on the threaded side of the joint body);
-
protection bellows.
Check and adjust the parallelism, if necessary.

Bellows
REMARK :
A damaged bellows is to be obligatory replaced with a new one.
BELLOWS
MOUNTING
Bellows mounting is performed by means of a con-shaped device that is positioned on the
connecting rod joint body (axial ball joint) for bellows easy sliding and avoid damaging.
Put some UM 185 Li2M grease on the bellows part in contact with the joint body (axial ball
joint), to easy the bellows sliding.
Mount a new collar for bellows maintaining on the steering box casing.
REMARK :
It is OBLIGATORY to bring the steering in the straight line driving position of the
front axle wheels (steering central point) in order to ensure the air balance inside the
steering box.
