All Volvos, except the 1988-89 760 and 780, use a coil spring rear suspension. The solid rear axle is suspended from the rigid frame member by a pair of support arms and damped by a pair of double-acting telescopic shock absorbers. A pair of torque rods control rear axle wind-up and a track rod limits the lateral movement of the rear axle in relation to the car. A rear stabilizer bar, attached to both rear support (trailing) arms, is installed on certain models.
In 1988, the 760 4 door sedan and the 780 model introduced Volvo's Multi-link suspension system. This independently suspends each rear wheel, allowing improved ride and road holding as well as allowing each rear wheel to be aligned separately. The rear suspension is two-way adjustable, allowing setting of camber and toe at the rear wheels. Caster is fixed by the design of the suspension and cannot be altered except by replacement of damaged parts.
Multi-link suspensions require alignment any time the suspension components are removed and installed. Position of components is critical as are torque values when retightening bolts. Multi-link repairs are discussed separately at the end of this section.
