I have a 07 plus4 with the standard steering bearings and the standard front springs and with no steering wheel shimmy. However I do know that the bearings are clean, not worn and that the dust shields are not tight. I went through a whole saga with the springs and I've ended up with standard front springs (approx 130lb)with cut down standard rebound springs as PJB suggests, see link below. The front end does not crash over bumps now, yes it's quite hard and Suplex would be softer. I have AVO dampers.
With regard to the front springs you need to read this:- https://sites.google.com/site/morganatica/suspension/main-rebound-spring-interation

YMMV.

Cheers
John

That's interesting.

You've found several millimetres of radial play and they go on to the rest. What makes them think the tyres are ok I wonder? I still think if you haven't had this issue for long, it's worthwhile getting two tyres off the rim and replacing them.

It's not unknown for tyres to bulge internally and cause wobbles, especially six year old ones on a car that's not in daily use..

You don't want too many people in this mix. Start from scratch and take it from there.

To be clear, I dont have a regular wheel wobble or shimmy any more. The issue, if indeed it is an issue, is the sensitivity to the road surface. Every little bump can be felt through the wheel. On a smooth dual carriageway the steering is fine now.

It always used to be said of Morgan suspension that you could tell which way up a coin was if you ran over one... grin2

They all do that Sir. That is fun of the set up, you are not isolated from the road.

Well I had tge front end up to do a proper greasing and cleaan off the old muck. Also rust treated the rack rods whilst I was there.

But the primary thing was to have a good poke about with the front suspension. It really is fundamentally flawed from an engineering perspective isn't it. The dampers twist in their mountings when you steer. The steering winds up or unwinds the springs (hence the bearings I guess). But there is more possibility of adjustment than I first thought. Not that I am going to go there... seems like a world of pain and I am under qualified to starting messing with it.
