Description
The i
ndependent rear suspension incorporates co-axial sp
ring and shock absorber units, a subframe, wishbone tie,
pendulum assembly, mounting brac ket, differential strut, cast wishbones and hub carriers. The suspension assembly is
positively located by the subframe, mounting bracket and differential strut.
Each wi
shbone pivots on a fulcru
m bolt which locates in the wishbone tie and pendulum assembly.
The wish
bone tie and pendulum assemblies are respectively in
stalled at the front and rear of the final drive housing.
The differential
strut is secured to the wishbone tie assembly.
Two ti

e rods are installed between the front of the
subframe and the top of the final drive housing.
The ou
ter extremity of each wishbone
is secured to its respective hub carrier assembly by a fulcrum bolt.
Each fulcrum bolt head incorporates an ec centric circular flange which locates in a groove in the front face of the wishbone
arm. Rotation of the fulcrum bolt results in horizontal movement of the bolt shank in an elongated hole in the rear of the
wishbone arm. This acti on achieves corresponding movement of the hub carrier, facilita ting adjustment of road wheel toe-
in.
