DESCRIPTION AND OPERATION
Front Suspension
Overview
N0TE:During installation of the front wheel bearing
it is important to adhere to the specified installation
position, as the anti-lock brake system
( ABS )
sensor ring is located in the wheel bearing. A
coloured rubber ring is provided to indicate the
correct installation position. If the wheel bearing
were to be installed incorrectly then this would
cause failure of the ABS
.
A newly developed Mc-Pherson front suspension
with L-shaped lower arms is used. These lower
suspension arms are linked via large rubber
mountings to a reinforced and extremely rigid front
axle crossmember.
The ball head between the lower suspension arm
and the suspension strut is secured with three
rivets. Toe-in is adjusted via adjustable track rods.
The lower suspension arms can only be replaced as a complete unit.

DESCRIPTION
AND OPERATION
Item Description
The rear rubber mountings for the lower
suspension arms are enclosed in aluminium
brackets. This provides more vibration damping
than previously. Both the front and rear brackets
are arranged horizontally.
1
The suspension strut turret support bearings have
two separate routes for independently deflecting
the spring and shock absorber forces into the body.
This reduces the level of noise transmitted from
the road surface. Rear rubber
mounting
The correct installation position must be observed
when installing the suspension strut turret support
bearings. This is indicated by an arrow on the
suspension strut turret support bearing. The shock
absorbers are gas shock absorbers.
The spring travel has been increased by
6 mm,
and the track has been increased by
48 mm to
1477 mm.
