Steering Overhaul

Steering linkage

Unwanted free play in the steering can be reduced by ensuring the steering joints are in good order. This will also reduce the possibility of experiencing the frightening and very violent 'steering shimmy', set off when a front wheel hits a bump or drops into a hole. When overhauling the steering we automatically incorporate improvements recommended by Rolls-Royce designed to reduce the likelihood of 'shimmy'. We pay particular attention to the steering joint at the bottom of the steering drop arm. Overhaul or renewal of this assembly can significantly improve the steering.

Rolls-Royce steering box

A number of the Rolls-Royce designed steering boxes suffer from 'sticky steering'. In many cases this effect can be reduced or eliminated by incorporating in the course of a steering box overhaul parts which we have developed.

As well as the 'small horse-power' steering box we can also overhaul some versions of the Silver Ghost steering box and the sttering box fitted to the Phantom 2 chassis.

Marles steering box

The later Marles steering box was considered to be a significant improvement over the Rolls-Royce box. However many of these are now in need of attention, with the development of excessive internal free play. Using replacement parts which we have manufactured the majority of Marles boxes can be returned to original condition.

The Marles steering box is designed to have no free play within the box in the straight-ahead position, and for about a quarter of a turn of the steering wheel on either side of this position. Beyond these limits there should be free play within the box, and on full lock the play is appreciable. This is by design and should not be a cause for concern.
