REAR AXLE COMPONENTS
Rear axle components: Precautions for the repair
33A
I - SAFETY
1 - Advice to be followed before any operation
For an operation requiring the use of a lift, follow the
safety advice (see
Vehicle: Towing and lifting ) (02A,
Lifting equipment).
2 - Instructions to be followed during the operation
Do not press on the brake pedal during work on the
brake system.
If, during work on the brake system, any damage on
any part is observed, it must be repaired before driving
the vehicle again.
Brake fluid is highly corrosive. Ensure any brake fluid
spilt on parts of the vehicle is cleaned off.
In case of incorrect handling, the brake fluid can cause
serious injury and damage. Follow the manufacturer's
instructions for brake fluid.
II - CLEANLINESS
1 - Advice to be followed before any operation
Protect any bodywork components that risk being dam-
aged by brake fluid with a cover.
2 - Instructions to be followed during the operation
Clean around the braking system with BRAKE
CLEANER (see Vehicle: Parts and consumables
for the repair ) (04B, Consumables - Products).
Do not allow friction materials to come into contact with
grease, oil or other lubricants and cleaning products
which are mineral oil based.
III - GENERAL RECOMMENDATIONS
1 - Bearing, stub axle carrier
During the bearing replacement operation, it is essen-
tial to check the surface condition of the hub, bearing
and stub axle carrier before refitting the bearing.
Replace any damaged hub carrier.
Use SURFACE CLEANER (see Vehicle: Parts and
consumables for the repair ) (04B, Consumables -
Products) to clean:
- the inner and outer surfaces of the new bearing in
contact with the stub axle carrier and the hub,
- the stub axle carrier surfaces in contact with the new
bearing,
- the hub surfaces in contact with the new bearing.
2 - Suspension spring
When replacing the spring, ensure that the positioning
and orientation of the spring and the tool cups are cor-
rect.
Check correct operation of the spring compressor.
In the interests of safety, do not leave a spring com-
pressed in the spring compressor tool.
When replacing a spring, always replace the spring on
the opposite side.
During assembly and removing operations, the surface
and the protection paint must not be damaged.
There must be no impacts during operations. Any han-
dling hooks and tightening or positioning clamps
should be equipped with rubber or plastic in order to
avoid damage on the springs.
It is recommended to replace springs if:
- the paint is damaged,
- there are dents on the spring.
3 - Rear axle
WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.
WARNING
To prevent the suspension spring from prematurely
breaking, do not damage the anti-corrosion protec-
tion.
WARNING
To prevent any damage, do not use the rear axle as
support for the lifting system.
WARNING
To prevent damage to the components of the rear
axle (rubber bushes, brake hoses, etc.) do not
remove both shock absorbers together. Proceed
one side at a time.
