1 General information
The front and rear suspension assemblies
and associated components are mounted on
subframes which are bolted to the underside
of the bodyshell. The subframes are of welded
all-steel construction, the front subframe also
providing mounting points for the
engine/transmission assembly.
The front suspension on all Mini models is
of the independent type, each side consisting
of an upper and lower suspension arm. The
lower arm is supported in rubber bushes at its
inner end, while the inner end of the upper
arm pivots on two caged needle roller
bearings. The outer ends of the two
suspension arms are bolted to the tapered
shanks of the swivel hub balljoints. Fore-and-
aft movement of each front suspension
assembly is controlled by a tie-bar bolted at
one end to the lower suspension arm and
mounted at the other end, via rubber bushes,
to the subframe. The swivel hubs contain
tapered roller or ball bearings which support
the outer ends of the driveshafts, and also
provide mounting points for the drum brake
backplate or disc brake calipers. Suspension
and steering movement of the swivel hubs is
catered for by adjustable balljoints.
The rear suspension on all models is also
independent by means of two trailing radius
arms. The forward end of each radius arm
contains a needle roller bearing and bronze
bush, which allows the arm to pivot on a shaft
bolted to the subframe. The brake backplate
is bolted to the rear end of each radius arm,
as is the stub axle which carries the rear
wheel hub and bearings.
While all Mini models share the same
suspension component layout, two different
types of springing and damping have been
employed. All models are now equipped with
dry suspension, whereby a rubber cone
spring and telescopic shock absorber are
fitted to the suspension assembly at each
wheel. Early Clubman and 1275GT models
were equipped with Hydrolastic suspension,
whereby a displacer unit which combines the
