REAR AXLE
Suspension bars, tubular rear axle
SPECIAL TOOLING REQUIRED
Emb. 880 Inertia extractor
TIGHTENING TORQUES (in daN.m)
Upper shock absorber mounting bolt 11.5
Lower shock absorber mounting bolt 8.5
REMOVAL
With the vehicle raised so its wheels hang free, re-
move the shock absorber on the side in question.
Remove the bar from the side, using tool
Emb. 880.
REFITTING
In order to position the suspension arm so that the
bar may be correctly positioned, a tool must be
locally made.
ANut, diameter 14 mm
BNut, diameter 12 mm
CThreaded rod, diameter 12 mm - length 660
mm
DBracket from flat sheet 30 x 5 mm
E 12 x 60 mm bolt, cut to a length of 20 mm

Preset the tool to obtain dimension "X".
X = 402 mm
Fit the tool in place of the shock absorber.
88637R2
Coat the splines of the bar with MOLYKOTE BR2,
fit it into the bearing and the suspension arm, and
try, by rotating the rod, to find the position where
it fits freely into the splines of the suspension arm
and the bearing.
Remove the tool and refit the shock absorber.
Return the vehicle to its wheels and measure the
underbody heights (see section "Underbody
heights - Tubular rear axle").
Check and adjust if necessary:
- the braking compensator,
- the headlights.

REAR AXLE
Four bar rear axle
The four bar rear axle comprises:
- two arms connected by an "L" section. This assembly (1) cannot be dismantled. Any deformation would
mean its complete replacement.
- two anti-roll bars (3),
- two suspension bars (4),
- a shackle (2) connecting the bars.
The assembly is connected to the body by two bearings mounted on rubber bushes.
NOTE : Never take the weight of the vehicle using a jack on the "L" section (1) to lift the vehicle.

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 first anti-roll bar, ensuring the angle of
the block is observed, and the bar is inserted
freely.

- 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.

Preset the tool to obtain dimension "X".
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" ).

Check and if necessary adjust:
- the braking compensator,
- the headlights.
REMINDER
When adjusting for a wheel height difference
between the right and left hand sides, always
make the adjustment on the anti-roll bars.
The adjustment for a difference in dimension " X"
between the right and left hand sides should
always be made on the suspension bars.

REAR AXLE
Suspension arm bearings
This operation is carried out after removing the
rear arms and the suspension bars.
REMOVAL
Totally immerse the bearing in brake fluid to
soften the rubber bush.
Using a two or three claw extractor, remove the
external part of the bearing by tearing off the
rubber.
Saw through the inner ring taking care not to
scratch in the tube of the arm.
REFITTING
The bearing is fitted in the arm on the press,
ensuring the correct alignment is observed and
the clearance between the bearing and the arm is
correct.
Alignment
Observe dimension "X" between the bearing
pressure face and the stub axle shaft:
X = 156 mm ± 3.5

Suspension arm bearings
This operation is carried out after removing the
rear axle assembly and the suspension bars.
REMOVAL
Weld a spacer (example : nut) in the central tube
of the bush.
Remove the bush - bearing assembly on the press.
REFITTING
The bearing is fitted in the arm, ensuring the cor-
rect alignment is observed and the clearance bet-
ween the bearing and the arm is correct.
Alignment
Observe dimension "X" between the bearing
pressure face and the stub axle shaft
X = 124 ± 3.5 mm
Clearance
In this position, press on the bearing until the
dimension between the bearing centres is :
Y = 1164 ± 1 mm
Fit the rear axle assembly to the vehicle and refit
the suspension bars (see corresponding section).
