| 600a To Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} from Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}1/AP.16.2.38 26.G.Vl.{V. Lewis / Mr Valentine} STEERING. So far as we can see your explanation of the clatter audible from the top of the steering column on corners must be the correct one. The same thing must occur on Ph.III. and 25/30. but for some reason is inaudible. Increasing the travel of the rear joint would undoubtedly help but we wish to avoid this if possible as it is bound to make the steering feel more spongy under emergency steering conditions, and will also make the steering gear go nearer the stops in the box when shunting. Your car has S.S. tube springs of lower rating than any other Wraith and the front wheels fight more owing to the heavy brake drums. We think that the clatter may be less audible if it occurs at the front end of the side steering tube instead of the rear end, so as soon as we are able to reproduce the clatter we intend to try reversing the S.S. tube back to front - the tapers of the ball pins are interchangeable.
