Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Steering Damper. 2004 Roadster

Varies automatically depending on speed, and you can also set the amount of assitance manually, or turn it off. Three of my friends have it, very happy. I have tried one of their cars. Of course wonderful at low speeds, good for parking etc. But I do not do that much tight parking, as I my car is not a daily driver and I never park it downtown. It is mostly in and out of my garage and a pit stop or three when touring. At higher speeds I did not notice much difference, but I might if spririted driving on twisty roads. Aprox. the equivalent of 2000 £ here in Norway. So it is quite down on the list, well after new shocks, possibly KP change etc.

There is a 10 amp fuse 18 on the engine fuse box that when removed kills the PAS John which may then answer your question. Unfortunately there is no wiring schematic shown in parts book for PAS. Note also the Canbus schematic is erroneously repeated twice more replacing correct diagrams for Wash/Wipe and Engine Ignition

Richard,
I am quite happy with it as it is. But thanks for the heads up. See you later for luncheon.

The EZ version is well developed...unfortunately not fitted to at least the last 4yrs of 3.7 production

Interesting comment. My tests of a trad roadster showed a steering whell that was "alive" in my hands. Unusual by modern standards but in some ways attractive. Presumably the result of a very basic old fashioned suspension system. Maybe a previous owner didnt get on with the idea of letting ths steering "work" in his hands and needed a firm grip on the wheel - hence a damper. Or is a damper standrad?

The steering wheel that is alive might well be "bump steer". This was a problem on early Roadsters because the track rod had the wrong angle related to the vertical axis of the road wheel. It is corrected on later cars, and can (could?) even be corrected on the affected cars, by re-machining the spindle, thus correcting the angle. I think MulFab offered this, not sure if they do it any more. Anyway, a steering damper can alleviate this, at least it did on my car. I used to have my hands really gripping the steering wheel all the time, the damper made the driving much more relaxed. It did not make the steering any heavier. When fitting it, I tested by grabbing the road wheels at 9 and 3, moving them back and forth (with the car on axle stands, of course) thus moving the steering wheel. This is a relatively slow movement, resembling my steering maneuvers. I did not notice any difference without and with the damper. When driving, though - the quick, sudden movements of bump steer or shimmy was efficiently dampened. It might also dampen very quick steering movements of the wheel, for instance when racing or when very spirited driving on a twisty road. But for cruising, my damper is working very well. To my knowledge a damper has never been standard.
