DESCRIPTION
The rear suspension design locates the rear axle with two round section steel lower link arms and a forged 'A' frame,
upper link assembly. This system allows maximum axle articulation and wheel travel while maintaining roll stiffness and
directional stability.
The link arm is secured by a single retaining nut to the chassis mounting, comprising a rubber bushed bracket, which is
retained by three fixings. A ferrule rubber bush with a single retaining bolt is used to secure the link arm to its axle
mounting.
The upper link assembly is located on the rear differential housing by a pivot ball-pin assembly. Two brackets bolted to
the chassis crossmember support both sides of the 'A' frame of the link assembly, secured by single retaining bolts.
A Boge Hydromat self levelling unit can be fitted, as an option, on 110/130 models to give additional support when the
vehicle is used to carry heavier loads.
Two rubber bearing bushes, with retaining straps, secure the rear of the stabilizer bar, if fitted, to the chassis
mountings, while bushed links support the front of the anti-roll bar to the axle.
Conventional long travel coil springs and hydraulic shock absorbers are used to control body movement. The shock
absorbers are secured to chassis mounting brackets and fabricated lower mountings welded to the rear axle. Retaining
plates are used to secure the coil springs to the axle mounting while fabricated brackets, welded to the chassis, are
used for the upper spring location.
