The removal - refitting procedure is the same for all
wheels.
REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aRelease the parking brake.
aRemove the trim.
aPosition the wheel so that the valve is at the top.
aMark the position of the wheel on the hub.
II - OPERATION FOR REMOVAL OF PART
CONCERNED
aLoosen the wheel bolts with the wheel on the
ground.
aRaise the lift.
aRemove:
-the wheel bolts,
-the wheel.
If the wheel cannot be removed after the bolt has
been undone:
aPosition all the wheel bolts.
aTighten the wheel bolts to bring all the bolt heads
into contact with the wheel.
aUndo the wheel bolts by one turn.aStrike around the edge of the tyre walls (1) several
times using a mallet on the inner and outer surfaces
of the wheel to detach the wheel.
aRemove:
-the wheel bolts,
-the wheel. Note:
This mark is required in order to:
-Note the original position of the wheel on the
hub,
-perform the balancing operation.
Note:
Use sockets with protective sheaths in order to
avoid scratching the alloy wheel rims.

WHEELS AND TYRES
Wheel: Balancing
35A
I - PREREQUISITES FOR WHEEL BALANCING
aWheel balancing is a measurement operation.
Several conditions must be met to achieve a reliable
result in a single operation.
The wheel balancer must be installed in accordance
with the manufacturer's instructions.
It is essential to calibrate the balancer according to
the frequency recommended by the manufacturer.
Do not grease the threaded shaft.
Check the condition of the supports, centring com-
ponents and mountings.
Replace any faulty parts (see manufacturer's in-
structions).
The wheel and the wheel balancer must be clean.
Driver's perception
aIf the wheels are not correctly balanced this causes
the steering wheel and/or the vehicle floor to vibrate.
These vibrations appear between 54 mph (90 km/h)
and 90 mph (150 km/h).
II - BALANCING PREPARATION OPERATION
aAdjust the tyre pressure (see 35A, Wheels and ty-
res, Tyre pressure: Identification, page 35A-10) .
aAlways carry out a road test for a minimum distance
of 1 mile (2 km) before balancing the wheels, in or-
der to remove any flat spots on the tread caused by
the vehicle being immobilised.
aActions to be carried out immediately after the test
drive:
-Position the vehicle on a two-post vehicle lift (see
Vehicle: Towing and lifting) ,
-raise the vehicle,
-leave the four wheels hanging free,
-release the parking brake.a
To reproduce the exact vehicle wheel assembly, use
a ring (1) of diameter:
a60 mm

Note:
The ring is available from the supplier of the
equipment used.
