Have just seen your e-mails as I am about to replace the vibration damper on my C180. If you have replaced your's yet I guess you found that removing the cross member gave better access. I believe the sliding joint allows the front propshaft to be moved back. Is this correct? Did you find that the vibration damper could be easily removed once the bolts were removed. My flexible coupling looks OK so I plan just to remove the damper. I believe the centre of the propshaft only needs to be disturbed if the rear flex coupling is to be replaced. I would be grateful for any advice.
