This is my workshop note Dave:
http://www.talkmorgan.com/ubbthreads.php/topics/554556/Workshop_Note_-Steering_Damper#Post554556I replaced my damper blades some time ago with Mulfab bearings, and the steering feel was transformed, but almost too light, because my age car has the lesser castor angle.....from the current arrangement.
It didn't wobble or dance but felt nervous with loads of feedback.
I discussed this with Keith Jackson at BHM, who agreed that my set up does produce nervous steering, and it was Keith who suggested the damper. I know it's counter intuitive to put more resistance into the rack, especially when some owners want power steering!, but I took Keith's advice and fitted the Mulfab damper.
I'm pleased with the result. The nervousness has gone, and the steering doesn't really feel any heavier.
