by the orrow
Fig.6.1/5-Preporing front oxle for the condition
of check lood by inserting
steel bors of 181 mm
in diometer ond obout
220 mm long
The most importont points
from the point
of
view of driving ore the
toe-in ond the comber
ongle, the odiustment of which is permitted
by
the oxle design.
Adiust first the comber
ond then the toe-in
since o chonged comber
offects the toe-in.
We refroin from describing in detoil ony
meosuring method in view
of the lorge number
of existing gouges.
Insteod,
we odvise you
to refer to
the procedures recommended
by the
monufocturers of the gouges.
The check lood con be formed by blocking the
wishbones with bors occording to
Fig. 6.1/5.
Press down the cor with the hond, insert
the
bors under the wishbones so
thot they
beor
ogoinst the oxle brocket, ond releose the cor
to
let the bors be clomped. lf
clomping of the
bors
does not toke ploce
(which con hoppen on on
older cor with weokened springs),
consider the
condition os if the bors were
clomped, i. e',
corresponding to the position of the
front oxle
ot check looding.
The words "ot
full lood" describe o vehicle
looded so thot the distonce of the rubber deod
stop from the bottom of the
lower wishbone
stop is 20 mm (see olso porogroph
18) ond the
comber ongle of the reor wheels is 1". Meosure
these volues on oll wheels (not
only one front
ond one reor wheel) ond distribute the
lood os
necessory.
Toe-in To odiust the toe-in, screw
the right-hond ond
left-hond steering rods
symmetricolly (o
chonge
up to 1 mm con be effected by
one rod) ot
check lood so thot the distonce between the
wheel rims (or
ocross them) behind the oxle
(A+o) is lorger by the toe-in volue (o)
thon the
distonce between the rims
in front of the oxle
(A). To verify steering symmetry (correct screw-
ing of steering rods during
toe-in odiusting),
check the wheel lock position ot the
20" lock
ongle of the neorside wheel -
for the respective
volues refer to Chopter 1.7.
Slocken the steering rod
nuts ond rotote the
steering rods using on
olligotor wrench (Fig.
6.1/6). In oddition to the correct inflotion
pressure
of the tyres, poy
ottention to
severol essentiol
points when checking the wheel
olignment:
o) Ploce thewheel in the stroight oheod trovel'
ling direction;
b) The
steering rod ond the trock rod
must
not
be stressed. The stress con be eliminoted by
letting the cor swing
up ond down in its
suspension under the pressure of
your
honds
(olternotely press down ond releose
the
wings)
c) Prepore the oxle os
shown in Fig.6.1/5;
d) lf
o speciol gouge with
o scole for wheel
lock ongle setting is ovoiloble, odiust
the cor'
rect length of steering rods in
occordonce with
the position
of wheels in
check lock positions.
You will find the respective volues
in Chopter
1.7 "Steering".
Set the lock ongle
of the wheel
on one
side to 20' (on
o turn-toble) ond screw
the steering
rod of the other wheel to odiust

1. Remove tlre shock obsorber ond fit the
MP 6-106 spring
instoller in its ploce from obove.
lnstoll o horseshoe wosher on the sphericol end
of the instoller tie-rod possing
tlrrough the
coil
spring ond the bottom wishbone, ond compress
portly the spring (for
fitting the instoller see
Fig. 6.5/4).
2. Screw off the
costellqted nuts of the upper
wishbone pin
ond the bolt of the lower wish-
bone suspension, ond drive out the wishbone

MP 6-105 Cortridge pin.
lf driving out is impossible, use the MP
6-107 drrog (remover).
Rotote slightly the
flonges of the drog to
breok it up in two ports,
fit it os o yoke
over
the upper wishbone,
clomp it in position
by
rototing its heod, ond screw in the centre bolt
to press
out the wishbone pin.
3. Drive out the bolt of the lower wishbone
suspension ond remove the steering knuckle
from the lower wishbone.
4. Screw off the nut of
the king pin
ond pull
off the king pin
socket using the MP 6'111 drog.
Refer to the following chopters for
further
dismontling of the steering knuckle, the king

5. When removing the upper wishbone, mork
the thickness of the open (horseshoe) woshers
irrserted between the brocket ond oxle body on
tlre individuol brockets. The
woshers ore 3
mm
onct 1 mm thick so thot if there ore, for exomple,
one 3 mm ond two 1
mm woshe'rs, mork the
thickness of 5 mm on the brocket. Also toke
into occount the likely necessity of o correction
of the wosher thickness -
see Chopter 6.2, poro-
groph 1. When reinstolling the upPer wishbone, fit
wo;hers of the morked down thickness to sim'
plify the cdjustnrent of the wheel comber.
