Here's a question about a real Jaguar.  When giving my '61 Mark 2 some real
Welly in a left hand (and only left hand) corner, or even a bit less stick
in a left hand corner and I hit a dip or bump in the road, I get this really
loud metal on metal rattattattat sound that I can feel through my feet.  I
can't see any shiny metal surfaces underneath, all steering bushes and sway
bar bushes are near new or new and all ball joints are sound.
Any thoughts?
