Thanks for this Alastair.
One other issue that I have on the car is a low noise "rumble" coming out of the back axle(well that area). Its particularly noticeable going very slow and especially in reverse with some steering -if you see what I mean. I took it to the independent Morgan specialist and he checked it all over and his conclusion was a very "tight" limited slip diff and he said it wasnt a problem. It doesnt sound healthy to me but I may be getting a bit over sensitive now !
Any thoughts?
Thanks
