Place the inside bearing’s outside ring (3) and use beater
99374093 (2) and handle (1) 99370007 to make setting.
Use general tools to remove the stud bolts (1) from the brake
disc (2).
Check that the supporting plane of the stud bolt heads is not
burred.
Lubricate the inside bearing with oil SAE W
140/MDA and place it on the wheel hub.
Set the sealing ring.
Reattach the wheel hub.
Check the wheel hub end play.
Check the rolling torque.

Replacement of wheel stud bolts
Place the stud bolts accurately putting on their heads
a load not higher than 2300 kg.
Once the operation is completed, check the lack of
clearance between the disc plane and the area under
the stud bolt head and verify that the orthogonality
error is not higher than 0.3 mm.

Screw tool 99370712 (3) on the steering knuckle pin and lu-
bricate its outside surface using oil TUTELA W 140/M-DA.
Secure the wheel hub (2) with a rope (1) and support it with
a lifter. Lock carefully the wheel hub (2) on the steering
knuckle pin in order not to damage the sealing ring (3,
Figure 35).
Mount spacer (4) and tapered-roller bearing inner race (5).
Release tool 99370712 (3).
Force-fit washer (6) and screw down retaining ring (7).
Tighten ring (7, Figure 40) to the specified torque by means
of wrench 99355038 (1).

Secure retaining ring (1) screw (2) to the specified torque.
Check wheel hub end play
Hit the wheel hub in axial direction with a mallet and rotate
it in both directions in order to release the bearings’ rolls.
Set the magnetic base (1) fitted with a gauge (2) on the wheel
hub.
Place the gauge pointer (3) perpendicular to the steering
knuckle shank (4).
Set the gauge to zero with a preload corresponding to 1.5
÷ 2 mm.
Move the wheel hub in axial direction by means of a lever and
detect the end play which must be 0.16 mm (maximum
value).
If the detected value does not correspond to the prescribed
one, replace the bearing unit and make a new survey.
Apply tool (1) 99395026 on wheel hub stud bolts and use
torque meter 99389819 (2) to check whether the wheel hub
rolling torque is at the set value.
Rotate the wheel hub until when hub cover (1) is positioned
as shown in the figure. Restore the prescribed quantity of oil
into the hub cover (1) through filling hole (2). Tighten the
plug on the hub cover (1) to the set torque.
Deposit a sealing bead (Loctite type 574) exclusively
on the hub cover ledge surface and protect the
threaded part.

Reattach the brake callipers (1) to the flange (3) and lock the
screws (2) according to the prescribed torque. Set braking
gaskets following the procedure described in chapter “Wheel
hub overhaul” Rear axle section.

Cross tie rod detachment and
reattachment
Straighten and take off the split pin (1).
Unlock the nut (2) and release it partially in order to prevent
the tie rod (3) from falling when it is removed.
Use extractor (1) 99347068 to unlock the articulated pin (3)
from the lever (2). Repeat the same operations on the oppo-
site side, release the nut (2, Figure 47) completely and re-
move the cross tie rod.
To reattach reverse the detachment operation
order.
Block the screw (4), release the nut (3) and unscrew the ar-
ticulated pin (2) from the cross tie rod (1).
Clamp the castellated lock nuts of the articulated
pins according to the prescribed torque.
!
Check that the nut grooves match with the cross
holes on the articulated pins. If it is not possible to
introduce the split pins, gradually raise the nut
tightening torque until the split pins are completely
put in place (angle lower than 60
°).

Replacement of cross tie rod
articulated pins
!
Write down the number of turns needed to release
every articulated pin in order to screw the new ones
making the same number of turns.
Screw the articulated pin (2) in the tie rod (1). The nut (3)
must be clamped according to the prescribed torque, after
making toe-in adjustment as described in the “Wheel set up”
chapter.

detachment and reattachment
Release the screws (2) and remove the brake callipers sup-
port (1) from the axle.
Loose the screws (1) and remove the upper cover (2) to-
gether with the lubricator (3).
Release the screws (5) and remove the cover (3) together
with the thrust block (2), the adjusting plate (1) and the lubri-
cator (4).
Use tool 99347047 (1) and element (2) to unfasten the
steering knuckle (4) articulated pin (3). Remove the tool, take
off the pin (3) and remove the articulated joint (4) from the
axle.
