Just to update you, despite the noise presumably made worse by load on the rear axle with heavy family members and luggage I managed to limp the car back to Santander and then limped it home from Portsmouth to Exeter, car left at Berrybrook and I also decided to fit a panhard rod.
Sorry about the spelling before android thingy decided to edit my typing, Mr Mog is a gentlemans auto carriage lowline of course not a lowlife!
Dunno why it decided it was a janice car?
