Three chassis mounting points, one for each lateral link, one for the trailing arm.
Three trailing arm mounting points, one for each lateral link and one for the trailing arm.
In this configuration, the axle hub and spindle and trailing arm are combined into a single assembly with the trailing arm attached to the chassis. There are two lateral control links which attach to the chassis and to the trailing arm assembly. The lateral control links are generally positioned on the axle centreline (in plan view). The driveshaft is often used as the top lateral link.
Vehicles with this type of rear suspension include the Lotus Europa and BMW E36 (both with coil springs) and pre 1984 Chevrolet Corvette (with transverse leaf spring).
Camber (and roll centre location) is primarily controlled by the pair of lateral links. Caster (and side view instant centre location) is primarily controlled by the trailing arm chassis mounting. Toe is primarily controlled by the chassis trailing arm mounting.
