Re: [Chrysler300] '56 Power Steering Hose

["johnl" <john@xxxxxxxxx>]

Jack and all,

I've had custom hoses made that were the same diameter from one end to the other.  Every time you turn the steering wheel, especially while idling there is a noticeable "rumble and vibration" that occurs.  I think this is why the engineers chose to use the reducer in the hose.
