Suspension: Description and Operation

The rear suspension utilizes coil springs over struts, and lightweight aluminum knuckles. Each wheel is mounted to a tri-link independent suspension system. The three links are identified as the inverted "U" channel trailing arm and the tubular front and rear rods.

Parallel links allow the rear wheels to deflect rearward when they hit a road hazard, but without moving the toe positive. An advantage of this suspension system is the reduction of unsprung and overall weight. Handling is improved with the independent action of each rear wheel. The rods control lateral wheel deflection.

Several techniques have been employed to achieve this independent wheel movement. The tri-link; design can be compared to a right angle. The wheel is located at the right angle formed by the rods and the trailing arm. The ends of the tri-links are "hinged" to provide vertical wheel travel. The solid links force the wheel to travel through a controlled arc with fore-aft position determined by the trailing arm and lateral position determined by the rods.

Aside from maintaining geometric wheel location, each portion of the suspension has additional functions. The knuckle supports the brake caliper. All brake torque and braking forces are transmitted through the tri-links and strut. The final duty of the rods are to maintain the camber angle of the wheel throughout its travel and allow for setting toe. The overall result of this rear suspension geometry is to maintain the rear wheels in a near vertical position at all times.

The stabilizer shaft is attached to the stabilizer bar drop link and extends rearward, where it is connected to the rear suspension support by two rubber bushings and mounting brackets.

A non-serviceable unit hub and bearing is bolted to the knuckle. This hub and bearing is a sealed, maintenance free unit.

The suspension system should be periodically checked for shock absorbency, bushing durability, tightness of attaching bolts and for any visible damage, misalignment or excessive wear.
