Rear axle components: Precautions for the repair
I - SAFETY
For an operation requiring the use of a lift, follow the
safety advice (see Vehicle: Towing and lifting) (02A,
Lifting equipment).
Brake fluid is highly corrosive. Ensure any brake fluid
spilt on parts of the vehicle is cleaned off.
II - CLEANLINESS
Protect any bodywork components that risk being dam-
aged by brake fluid with a cover.
Clean around the braking system with BRAKE
CLEANER (see Vehicle: Parts and consumables
for the repair) (04B, Consumables - Products).
WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.
III - GENERAL RECOMMENDATIONS
1 - Braking
Replace all the brake pads on one axle at the same
time. Never mix brake pads of different brands or qual-
ity.
Lightly coat the threading on the support linkage with
GREASE BR 2 + (see Vehicle: Parts and consum-
ables for the repair) (04B, Consumables - Products).
The brake mechanism components are different on the
left and right-hand sides, so it is essential not to con-
fuse them. On the left-hand brake: the bolt thread has
a right-hand thread. On the right-hand brake: the bolt
has a left-hand thread.
Adjust the brake pads by depressing the brake pedal
repeatedly.
IMPORTANT
To avoid brake imbalance, both drums must be of
the same diameter. Regrinding one drum necessi-
tates regrinding of the opposite drum.
2 - Rear brake drums, rear brake pads
Remove all dust from the drums and the backplates us-
ing brake cleaner.
To ensure the wheel speed sensor operates correctly,
do not mark the sensor target on the drum's magnetic
ring gear.

3 - Suspension spring
When replacing the spring, ensure that the positioning
and orientation of the spring and the spring compres-
sor tool cups are correct.
Check that the spring compressor tool is operating cor-
rectly.
WARNING
To prevent the suspension spring from prematurely
breaking, do not damage the anti-corrosion protec-
tion.
In the interests of safety, do not leave a spring com-
pressed in the spring compressor tool.
4 - Rear axle
The shock absorber mountings are only to be tightened
with the vehicle wheels on the ground.
Always replace the shock absorber upper mounting
nut.
WARNING
To prevent any damage, do not use the rear axle as
support for the lifting system.
WARNING
To prevent the components of the rear axle from
deteriorating (rubber bushes, brake hoses, etc.) do
not remove the two shock absorbers at the same
time. Proceed one side at a time.
