Oscillation trepidation !

[Ian Williams]

I am just catching up with this thread. I suggest as the car has been in an accident you take a very careful look at the castor angle. I would suggest that it is highly probable the front crossmember has be pushed back in the area where the radius arm ball mounts. Even a small distance will upset the geometry and lack of sufficient castor together with wheel balance have been responsible for any experiences I have had of shimmy in an A7
