Hi all, thanks for all the replies telling me that it was the spigot bush that had gone on the clutch; spot on. Now I need to know how to remove the centre trims (side of driver) so I can root the coax for my amateur radio antennas.
I did discover (for all those amateurs who want to know) that it is ok to transmit 100 watts of power up to the antenna without it intreferring in any way with the ECU, providing that it is sheilded correctly so no stray RF goes whizzing around.Sourced from Lode Lane technical dept.
