Aston Service Dorset : Suspension & Steering


The rear suspension is of the trailing arm type with parallelogram linkage with coil springs.

Both the top and bottom arms are mounted by means of rubber bushes at their forward end and on the axle tube at the rear, the lower arms forming the base for the coil springs.

Sideways location of the axle is controlled by a Panhard rod mounted in rubber bushes and is fixed at one end to the axle and to the frame at the other.

Below is a selection of the parts that we can provide for the rear suspension

Aston Service Dorset: Front Suspension


The front wheels are independently sprung by means of trailing arms and coil springs.

The lower arm is mounted on needle roller and ball bearing in the front cross member, and carries the stub axle which also forms the base for the coil spring.

The offside and nearside arms are connected by an anti-roll bar which passes through the front cross member.

The Front Suspension is split across three sections in the Parts Catalogue and this is replicated below:
