Engineer}8/AP.23.2.38 6.B.1V. and 26.G.V1. STEERING. As 6.B.1V. will low speed wobble will you please check the friction load of the cross steering tube joints. We are sending you a lever for doing this together with a number of washers to pack up the springs if necessary. The attached sketch No.1. shows how the lever should be used. The load should be from 5 to 6 lbs. at the end of the lever (12"). Will you please let us know the existing load, and whether the car will still wobble with the standard poundage. We have recently found on our Wraith chassis which have centre steering levers similar to yours that a foul can occur as in sketch No.2. between the front joint of the side steering tube and the head of a set screw on the O.S. damper bellows casing. Will you please investigate whether this can occur on 26.G.V1. and, if so, replace the cheese headed screw by the countersunk headed screw we are sending to you . Is it possible that this foul is the cause of the rattle.? With reference to your memo of 21.2.38 do not reverse your side steering tube until we let you know the results of our tests.
