REAR AXLE
Four bar rear axle
SPECIAL TOOLING REQUIRED
Emb. 880 Inertia extractor
TIGHTENING TORQUES (in daN.m)
Upper shock absorber mounting 8.5
Lower shock absorber mounting 11.5
Wheel bolts 9
REMOVAL
Remove:
- the wheels,
- the shock absorbers,
- the suspension bar plugs.
Remove using tool Emb. 880 :
- the two suspension bars,
- the two anti-roll bars, retaining the central
shackle.
Clean and lubricate the bar splines using
MOLYKOTE BR2.
REFITTING
The anti-roll bars cannot be removed from the
vehicle when the shock absorber replacement tool
is in position. Because of this, and to make it
easier to refit the shackle, a wooden block must
be made according to the diagram below.
Fit:
- the shackle on the block (locally made) in the
centre of the rear axle assembly,

- the second anti-roll bar, ensuring it engages
freely.
In order to position the suspension arm so that the
bar may be correctly positioned, a tool must be lo-
cally made.

X = 430 mm
Fit the tool in place of the shock absorber.
Refit:
- the bar plugs,
- the shock absorbers,
- the wheels.
Put the vehicle on its wheels and measure the un-
derbody heights ( see section "values and set-
tings" ).

REFITTING
Assembly (2) MUST be renewed systematically.
83510-1R3
Refit to the rack (3) :
- the stop washer assembled with the locking
ring (2),
- the new axial ball joint (1) having lightly coated
the threads with
LOCTITE FREN-BLOC, ensuring
that the air evacuation opening is not blocked.
Before finally tightening the axial ball joint using
tool Dir. 1305-01, check that the tabs on the
locking ring (2) align with the flats (B) on the rack.
Tighten the axial ball joint to the recommended
torque.
Centre the steering to equalise the air in the
gaiters.
Fit a new gaiter and secure it with a new clip
(after greasing the gaiter bearing surface on the
axial ball joint).
Checking
Gently press on the gaiter to check the other
gaiter inflates which indicates the air is circulating
correctly.

1. Determining the source of the noise
Hold the steering rack on the pinion side and
check for transverse play (up and down).
Movement followed by a click is caused by the
pinion.
2. Adjusting for SMI steering racks
Release the adjusting nut (1) by straightening the
bent over edges (A) on the nut collar.
Check when driving that the steering returns to
the centre point.
Maximum adjustment allowed : 1 notch.
Lock the nut again in the two lugs opposite the
housing by bending over the nut collar.
ADJUSTMENT
If the steering rack pinion is noisy, before considering replacing the steering rack, check that the pinion is
correctly adjusted.
