+8380 To D.A. from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} c. to EY. PHANTOM - SPARE WHEEL CARRIER. +8600 We have revived an old trouble with the spare wheel carrier on the rear of the Phantom. This is a some- what elusive knock due to the flexing of the rear end of the cantilever frame when :- (1) Luggage is being carried. (2) Hartfords have been over tightened or become almost solid with neglect. (3) Recently the spare wheel carrier at the rear. On subframe cars we do not get the trouble if the body clearance is correct. So far the carrier has largely been run on chassis with 'subframe' bodies - 7-EX and 8-EX. We suggest a rubber pad to be fixed at the point where this knock takes place to remove the objection. Apart from the audible noise, there does not seem to be any sensible effect on the passengers. As the rear wheel carrier has now been standard- ised we should like this point to receive immediate attention. Report attached.
