Use drift 99374093 (2) to press-fit the outer race of the front
hub bearing without pushing fully home. Repeat the
operation on the opposite side for the rear bearing outer
race.
Complete the operation of press-fitting the outer bearing
races manually using drift 99374093 (2) with handle
99370007 (1).
Heat the phonic wheel (1) to a temperature of 150

° (3,

Figure 28) for 15 minutes, then fit it on the wheel hub (1) and
let it cool down.

Lubricate the inner bearing with SAE W 140M-DA
oil and position it in its housing in the wheel hub.
Using drift 99374232 (1) and handle 99370006 (2)
fit in place the seal ring (3) on the wheel hub checking
the assembly position (Figure 32).

Use ordinary tools to remove studs (1) from wheel hub.
Check that the stud head mating surface is free of burrs.
Press-fit studs carefully by applying a load of not more than
2500 kg to their heads.
Once the operation is complete, check there is no play
between the disc surface and stud head undersides.

Replacing wheel studs

Cleaning the wheel hub cap. To prevent the
polycarbonate transparent part from getting opaque,
we advise you to wash it with cleaning products
normally used for the body. Never use chlorotene
solvents because they etch the polycarbonate.

Make sure that the surfaces of all components
inside the hub are thoroughly clean and free from
scale and burrs.

Adjusting wheel hub bearing end play

49181

Using a torque wrench (2) and wrench 99388001 (2) lock
the adjustment nut to the prescribed torque.

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.

Figure 36

Give wheel hub a few blows with a mallet in axial direction,
rotating it in both directions to free the bearing rollers.
Apply magnetic base (1) with gauge (2) to the wheel hub.

Install the wheel hub onto the stub axle.
Fit the internal spacer onto the stub axle, then
position the outer bearing and thrust washer.

Put stylus pointer (3) perpend. to the stub axle (4) spigot.
Zero the gauge with a preload of 1.5 to 2 mm.
Use a lever to move the wheel hub along the axis and
measure the end play which should be 0.16 mm (max. value).

If the end play is not as required, replace the bearing
assembly e repeat the adjusting operations.

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.

To refit, carry out removal operations in reverse
order.

Tighten the nuts securing the taper pins to the
specified torque.

Check the position of the castellations on the nuts
which line up with the transverse holes in the taper
pins; if the cotter pins will not go in, progressively
increase the torque of the nuts until correct
insertion is achieved (angle less than 60

°).

Straighten and extract cotter pin (1).
Unlock nut (2) and partially unscrew it so as to prevent the
track rod from dropping when removing.

Using the extractor 99347068 (1), release the ball joint (3)
from the arm (2).

Repeat the same operations on the

opposite side, unscrew the nuts completely and remove the
track rod.

REPLACING TRACK ROD BALL
JOINT

Before replacing swivel head (Figures 40-41) check the axial
clearance as described below.

Lock screws (4), loosen nut (3) and unscrew ball joint (2)
from track rod (1).
Screw ball joint into rod and lock in position tightening
locking nut to the specified torque.

To make it easier to refit the track rod and measure
the wheel convergence, note down the number of
turns needed to unscrew each ball joint so that the
new ones can be screwed in by the same number
of turns.

Refit the track rod.

Check and, if necessary, adjust front wheel toe-in as
described on “Front wheel set up”.

The vehicle should not be jacked up.
Use a gauge (1, Figure 40) to measure the distance ”X” with
the vehicle in straight on position.
Take the measurement again with the steering turned as far
as possible, to the left (X1) and to the right (X2). Take a note
of the values measured.
Calculate the axial clearance ”A”, noting the maximum value
measured between X1 and X2.
Example:

A = max (X1, X2)-X

If the value rises above 2 mm replace the ball joint.
