Iveco Stralis AT/AD. Manual — part 182
Position the vehicle on level ground and lock the rear wheels.
Loosen the fixing nuts of the front wheels. Put a hydraulic jack
fitted with mount 99370628 under the axle (34).
Lift the vehicle at the front and rest it on two stands. Again using
the hydraulic jack and mount 9937628, support the axle so that
the longitudinal bars (3) and (5) are parallel with the chassis
frame.
Unscrew the wheel fixing nuts and, using the hydraulic trolley
99321024, take off the wheels.
Remove the cabin accessing platform, if needed. Take out the
bolts (7) and detach the board mount (8).
Disconnect the steering tie rod (9) as follows: Take out the split
pin (22) and the nut (21) (det. A).
Using the extractor 99347068 (23) disconnect the swivel head
of the tie rod (19) of the lever (20).
Disconnect:
- The diaphragm brake cylinder air delivery pipes(28);
- Extract the speed sensor (17) from the brake calliper
supporting flange (18);
- Take out the screws (30) and extract the brake lining wear
sensor (31) (det. B);
- Take out the fixing screws (13) and remove the bracket
(14) anchoring the levelling valve tie rod (27);
- Take out the screw (24) and remove the shock absorber
(29) from the mount (16);
- Take out the screws (15) and remove the air spring (26)
from the mount;
- Remove the screw (11) and disconnect the stabilizer bar
(12) from the connecting rod (10);
- Take out the screws (6) and disconnect the bottom rod (5)
from the mounts (4). Repeat these operations for the top
rod (3);
- Repeat the above operations for the opposite side;
- Take out the screws (25) and disconnect the transverse bar
(1) from the mounts (2);
- Lower the hydraulic jack and take the axle out from under
the vehicle;
- Take out the screws (33) and disconnect the stabilizer bar
(32) from the axle (34) (det. C);
- Take out the screws (35) and disconnect the mounts (36)
from the axle (34) (det. C).

REMOVING AND REFITTING AXLE

Figure 6
- Tighten the nuts or the screws to the required torque.
- The self-locking nuts must not be reused.
- Check the state of the flexible pads, and change them if
they have deteriorated (operation 500417).
- Using a hydraulic jack fitted with the mount 99370628, lift
the axle so that the leaf spring mating pins go into the
holes made on the leaf supporting surfaces on the axle.
- Check and if necessary adjust the geometry of the front
wheels.
Refitting
For refitting, carry out the steps described for
removal in reverse order while observing the
following:
The connection of the swivel head shanks (2) of the
longitudinal rods (1) to the mounts of the chassis frame and
of the axle has to be made when there is a distance X between
the mounts (5) and structural members (6) of X = 154 mm.
The connection of the swivel head shanks (3) of the Panhard
bar (4) has to be made when there is a distance X between
the mounts (5) and structural members (6) of X = 224.5 mm.
AXLES 5876/4 (F 8021) - 5876/5 (F 8021) - 5886/5 (F 9021) - 5876/2 (F 8021)

Clean the swivel heads of the tie rods: transverse and
longitudinal.
This needs to be done with dry canvas or raw cotton, never
use solvents.
Check that the various components of the swivel head have no
points of corrosion deeper than 1 mm; in particular, check the
sheet metal cover near the roller.
Check the protective cover:
- It needs to be secured to the body and to the pin of the
articulation with split rings and it must not turn.
- It must be neither deteriorated nor damaged.
- Press on the protective cover and check that grease
comes out.
- Check that the nut and split pin have not deteriorated.
Check bolts and nuts retaining clamps to track rods and drag
links are not damaged and are tightened to specified torque.
Track rods and drag links should not be damaged or worn. The
threaded part should be in good condition.

Put the vehicle on the lift or over the pit and do not lift the
wheels.
Using a gauge, measure the distance between the body of the
swivel head and the end of the pin, making three measure-
ments in the following conditions:
CHECKING SWIVEL HEAD PLAY
-wheels straight
measurement X;
- wheels turned lef
measurement X
1
;
- wheels turned (fully to the right)
measurement X
2
.
Calculate the play A according to the following formula:
A = B - X
where B is the larger of the measurements X
1
and X
2
.
This play must be no greater than 2 mm.
If you find the play to be greater or any of the problems listed
in the checks, replace the part concerned as described under
the relevant section heading.

Remove the brake pliers as described in the ”BRAKE AIR
SYSTEM” Section.
Turn the wheel hub so that the screw plug (1) goes down, un-
screw the plug (1).
Using the reaction lever 99370317 (3), lock the rotation of the
wheel hub and, using wrench 99354207 (2), unscrew the oil
cover (1). Bleed oil completely.
Undo the screw (4), take out the adjustment nut (3) with the
wrench 99388001, extract the washer (2), the outer bearing
and remove the wheel hub (1) together with the spacer and
internal bearing.
Examine the state of wear of the brake disc (3) as described
in the ”BRAKE AIR SYSTEM” section.
To remove the brake disc (3), take out the screws (1) and
disconnect it from the wheel hub (2).
Using a lift, position and secure the axle assembly on the stand
99322215 for overhaul.
