There is however a feeling of unstableness when going fast.
It is the same feeling which forced us to adding extra friction to the present 20 HP. steering. We are trying the alternative scheme of using a plain bearing at the bottom of the pivot on India with F.W.B. We think it is definite that the steering will have to be made more stable before we could deliver cars to customers.

(7) Very rapid wear has taken place on the worm wheels driving the servo. This allows considerable rotational movement on the servo shaft. This makes itself manifest on the car by causing a rattle especially noticeable between 40 and 50 m.p.h. The rattle is overcome if slight braking is put on the servo shaft. We notice the type of worm used on the India is the straight worm - on the EAC. we use a formed worm. It is doubtful whether the worm wheel in the gearbox obtains sufficient lubrication. We are investigating this. Something will certainly have to be done to prevent the very rapid wear which has occurred in 400 to 500 miles running.

(8) The tendency for the steering to take charge when the brakes are applied is definitely worse on the India compared with the EAC. The EAC. has this fault and has probably been the cause of two accidents. We suggest the front brake on India is reduced. We also propose to measure the twist on the front axle when the brakes are applied.
