Re: Chassis No.B.10.MR - Mr. E.{Mr Elliott - Chief Engineer} Dubonnet. We are at a loss to understand why the steering of Mr. Dubonnet's Bentley should have more reactions than usual, and, at the same time, be stiff. We do not recommend weaker springs in the side steering tube owing to the risk of low speed wobble when the tyres are worn. The side steering tubes on 'M' Series cars is idential to previous series except for length. The cross steering tube and axle are also identical. We can only suggest that you should examine the ball joints of the side and cross steering tubes and the stub axle pivots for signs of picking up or lack of lubricant. In connection with the reactions, we suggest that you check the balance of the front wheels, change the front tyres if these are worn unevenly, and make sure the front dampers are working correctly. The preload of 1¼ to 1½ lbs on the steering gear is correct. As requested we are sending to you the following prints:- FB.2753 - Side Steering tube arrangement.
