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.
