Many thanks for the reference to the andyspares site. Your are right of course - the answer was there. New spheres will be ordered but at a fraction of the Main Dealer cost. Thanks again, Corky. :) 2 new front spheres, £40.00, a 12mm spanner and 30 minutes were all that were required (once I managed to loosen the spheres, that is) - no problem! The car now drives and feels as intended.
