REPLACING THE BEARINGS

Read through the paragraph (PRECAUTIONS AND
GENERAL INFORMATION).
CAUTION
The bearings must be checked and if necessary
replaced every time they are removed.
Clean both sides of the hub with a rag.
Removal
Working on the left side of the vehicle:
Insert a drift (with no point) into the wheel hub and act
on the inner race of right-hand bearing (1), taking care
to shift the strike points (by 90°) so as not to offset the
bearing.
Extract right-hand bearing (1).
Extract spacer (2).
Working on the right side of the vehicle:
CAUTION
Maintain the drift perpendicular to the bearing (on
the same axis as the axle) to avoid offsetting and
damaging the latter.
Insert a bumper with diameter of 15 mm (0.59 in) into
the wheel hub and lean it against the ring inside the
left bearing (3).
Drive out the bearing by repeatedly hitting the drift
with moderate force with a plastic mallet.
Refitting
Working on the right side of the vehicle:
Rest the bearing on the wheel hub.
CAUTION
Maintain the drift perpendicular to the bearing (on
the same axis as the axle) to avoid offsetting and
damaging the bearing.
Lean a bumper with diameter of 31 mm (1.22 in)
against the bearing outer diameter.
Fully insert right-hand bearing (1) by repeatedly hitting
the drift with moderate force with a plastic mallet.
Fit spacer (2).
Working on the left side of the vehicle:
Repeat the first three steps for left-hand bearing (3).
WARNING
Check the bearings centering to the wheel hub.
