The type of rear suspension required depends
on whether the vehicle is front or rear wheel
drive and the weight and performance characterisitics
of the vehicle.

Leaf Spring

Rear Leaf Springs are used at the rear of trucks, some full
sized cars, and some minivans.  The rear leaf does not
provide as much independant rear suspension as a coil
spring.  The leaf spring is fastened to the axle, and helps
to prevent fore and aft movement.  A shackle at the rear of
the spring allows it to change length without
changing the position of the axle.

Rear Coil Springs

Rear Coil Springs require a lower suspension arm to attach the
axle to the frame.  The upper and lower suspension arms
hold the rear axle in position.  This system can be used with
front or rear wheel drive rear axles.

Independant Rear Suspension

This particular rear suspension system uses coil springs
between a lower arm and the frame.  The spring could
also be located on the strut.  Notice the tie-rod that
keeps the rear spindle in position.  This rod may provide
adjustment for toe-in as will be seen later.
